217.84.7.147:

The Foenix F256K and Jr.computers contain 512K of flash ROM which is intended to store software which should be available to the user without any media like SD-cards or IEC drives present. This collection of software can be changed by the user by simply reprogramming the flash ROM. At the moment the following applications are stored in flash as a default

* The Kernel
* SuperBASIC
* pexec, a tool to start executables in various formats
* wget, a tool to download data from webservers (if you have TCP networking enabled)
* An online help system for SuperBASIC
* A file manager
* A simple command shell

and therefore make up the firmware of the Foenix computers.The current version of the F256K and F256Jr. firmware can be downloaded [https://github.com/FoenixRetro/f256-firmware/releases here].

Getting Started

2024-03-30T13:44:06Z

217.84.7.147:

== Getting Powered Up ==

=== Powering your F256K ===

The F256K is powered via a standard 2.5mm DC Connector, which takes a centre-positive 12V 2A capable Power Supply.

This type of power supply is quite common. [https://www.amazon.com/Adapter-100-240V-Transformer-Charger-Security/dp/B091XSVV1Y Example 12V 2A capable power supply] (#)

(#) ''This specific power supply has not been verified (by the author) for use with the F256K. Please update this page with verified options!''

=== Powering your F256Jr ===

The F256Jr is supplied as a Mini-ITX form factor mainboard, with a standard 24 pin ATX power supply connector for power connectivity.

Since the F256Jr needs relatively little power, compared to a mini-ATX PC, a popular DC 12V 24pin Pico ATX PSU works well and is a compact solution.

* [https://www.amazon.com/dp/B08F57GKCL Pico PSU] - You power the Pico PSU via a 12V DC center-positive Power Supply source.
* [https://www.amazon.com/dp/B07MXXXBV8 12V DC center-positive A/C Adapter] - Commonly used to power the Pico PSU.
The board itself has no power switch. If you do not have a Mini-ITX case, a pin header on the board can be bridged by a jumper and thereby used instead of a proper power switch as a stop gap solution. In this picture https://wiki.c256foenix.com/images/6/64/Pinout_Jr_December_7th_Trans.png the pin header in question is shown in the lower right and is labeled with ''PW ON SPST Switch''.

== Getting programs onto the F256 ==

=== SD Card ===

Both the F256K and F256JR have an SD card slot. The device software to read the SD card is a bit touchy (it's inherited from the Commander X16 project) and doesn't work with all SD cards

* Cards should support the V2 protocol (HC or XC); older cards that only support the V1 protocol (typically 2GB or less) won't work. By contrast, the kernels for the C256 machines generally only work with V1 cards. Note that, in both cases, this is a software limitation -- all of the Foenix machines are electrically capable of using both kinds of cards.
* Cards *MUST* be formatted FAT32 -- **NOT: FAT, FAT12, FAT16, or exFAT**.
* Formatting with Windows 10/11 works fine, but make sure to force FAT32 (or use the command line: <code>format /FS:FAT32 H:</code>)
* Formatting with MacOS will only work using the <code>diskutil</code> command line utility. An example usage looks like this: <code>sudo diskutil eraseDisk FAT32 [DiskName] MBRFormat /dev/[DiskNumber]</code>. You can use <code>diskutil list</code> to get the disk number for the SD Card.
* Formatting and partitioning SD cards with Linux can be done using the <code>gnome-disk-utility</code> (known simply as Disks) and is installed on most mainstream distributions of Linux. Disks will access all the drives on the computer so be sure you have the SD card selected when editing. [https://wiki.gnome.org/Apps/Disks Gnome/Disks wiki]
* FAT32 only supports a maximum partition size of 32Gb, on larger cards you will need to create multiple partitions -- however, only the first is recognized by DOS.
* Some folks have had luck formatting cards with the [https://www.sdcard.org/downloads/formatter/sd-memory-card-formatter-for-windows-download/ Official SD Association formatter for Windows].

=== Demos Archive ===

* [https://github.com/FoenixRetro/Documentation/blob/main/f256/archive Download the most recent demos archive] and expand it to the root of the flash card.

=== Debug USB port ===

* This is what most developers use as it's the most convenient. Connect the debug USB port to your PC or Mac

* You can use:
** [https://github.com/pweingar/FoenixMgr FoenixMgr] - works on Windows, Mac, Linux
*** A Python script to manage the Foenix series of retro style computers through their USB debug ports. This tool allows uploading files of various formats to system RAM, and displaying memory through various means.

** [https://github.com/Trinity-11/FoenixIDE FoenixIDE] (Windows only)
*** Development and Debugging Suite for the C256 Foenix Family of Computers.

=== wget ===
If you have the [[wifi]] configured, you can use [https://github.com/ghackwrench/F256_wget wget] to pull programs and data right off the web!

== SuperBASIC ==

The machine boots to SuperBASIC. SuperBASIC is inspired by BBC BASIC but offers quite a bit more.

* Read the [https://github.com/FoenixRetro/f256-superbasic/blob/main/reference/source/f256jr_basic_ref.pdf SuperBASIC Reference Manual].

* Watch EMWhite's excellent intro series on Youtube:
** Full Playlist here: [https://www.youtube.com/playlist?list=PLeHjTvk7NPiSqGz4REMH-S4hjYpLS2YNR EMWhite's Intro Series - Full Playlist].
** Part 1 can be viewed here:
<youtube>G_S2c_MsqYA</youtube>

To get started, you can type in a sample program at the command prompt:

<pre>
10 for i=1 to 5
20 print "Hello world"
30 next
run
</pre>

SuperBASIC is similar to CBM (Microsoft) BASIC but has some differences. For example, note in the sample above it's just <code>next</code> not <code>next i</code>.

The first 15 or so pages of the [https://github.com/FoenixRetro/f256-superbasic/blob/main/reference/source/f256jr_basic_ref.pdf SuperBASIC Reference Manual] are quite instructive.

SuperBASIC is actually much more powerful and supports structured programming (procedures, blocks etc.)

<code>dir</code> - Run this to display directory of SD card

Loading & running programs off of the SD card is similarly easy:

<pre>
load "JrWordl.bas"
run
</pre>

Similar to the C64, you can save time in loading programs from the <code>dir</code> listing by using your cursor keys to go up to the entry, typing <code>load "</code> (insert mode is active by default) etc. You can use <code>CTRL+E</code> to jump to the end of the line and use <code>CTRL+K</code> to delete any text from the cursor to the end of the line. Correctly place the closing <code>"</code> and hit <code>ENTER</code>.

<code>CTRL+C</code> acts as a "break" command and stops any running SuperBASIC program or <code>LIST</code> command.

Read built-in help/reference:

<code>/help</code> : But '''NOTE''', this erases BASIC memory! Use Backspace key to go back in menus and to exit.

To get started, you can type in a sample program at the command prompt:

<pre>
10 for i=1 to 5
20 print "Hello world"
30 next
run
</pre>

SuperBASIC is similar to CBM (Microsoft) BASIC but has some differences. For example, note in the sample above it's just <code>next</code> not <code>next i</code>.

The first 15 or so pages of the [https://github.com/FoenixRetro/f256-superbasic/blob/main/reference/source/f256jr_basic_ref.pdf SuperBASIC Reference Manual] are quite instructive.

SuperBASIC is actually much more powerful and supports structured programming (procedures, blocks etc.)

<code>dir</code> - Run this to display directory of SD card

Loading & running programs off of the SD card is similarly easy:

<pre>
load "JrWordl.bas"
run
</pre>

Similar to the C64, you can save time in loading programs from the <code>dir</code> listing by using your cursor keys to go up to the entry, typing <code>load "</code> (insert mode is active by default) etc. You can use <code>CTRL+E</code> to jump to the end of the line and use <code>CTRL+K</code> to delete any text from the cursor to the end of the line. Correctly place the closing <code>"</code> and hit <code>ENTER</code>.

<code>CTRL+C</code> acts as a "break" command and stops any running SuperBASIC program or <code>LIST</code> command.

Getting Started

2024-03-30T13:36:53Z

217.84.7.147:

== Getting Powered Up ==

=== Powering your F256K ===

The F256K is powered via a standard 2.5mm DC Connector, which takes a centre-positive 12V 2A capable Power Supply.

This type of power supply is quite common. [https://www.amazon.com/Adapter-100-240V-Transformer-Charger-Security/dp/B091XSVV1Y Example 12V 2A capable power supply] (#)

(#) ''This specific power supply has not been verified (by the author) for use with the F256K. Please update this page with verified options!''

=== Powering your F256Jr ===

The F256Jr is supplied as a Mini-ITX form factor mainboard, with a standard 24 pin ATX power supply connector for power connectivity.

Since the F256Jr needs relatively little power, compared to a mini-ATX PC, a popular DC 12V 24pin Pico ATX PSU works well and is a compact solution.

* [https://www.amazon.com/dp/B08F57GKCL Pico PSU] - You power the Pico PSU via a 12V DC center-positive Power Supply source.
* [https://www.amazon.com/dp/B07MXXXBV8 12V DC center-positive A/C Adapter] - Commonly used to power the Pico PSU.
The board itself has no power switch. If you do not have a Mini-ITX case a pin header can bridged by a jumper in order to connect the power supply to the board as a stop gap solution. In this picture https://wiki.c256foenix.com/images/6/64/Pinout_Jr_December_7th_Trans.png the pin header in question is shown in the lower right where it is labeled with ''PW ON SPST Switch''.

== Getting programs onto the F256 ==

=== SD Card ===

Both the F256K and F256JR have an SD card slot. The device software to read the SD card is a bit touchy (it's inherited from the Commander X16 project) and doesn't work with all SD cards

* Cards should support the V2 protocol (HC or XC); older cards that only support the V1 protocol (typically 2GB or less) won't work. By contrast, the kernels for the C256 machines generally only work with V1 cards. Note that, in both cases, this is a software limitation -- all of the Foenix machines are electrically capable of using both kinds of cards.
* Cards *MUST* be formatted FAT32 -- **NOT: FAT, FAT12, FAT16, or exFAT**.
* Formatting with Windows 10/11 works fine, but make sure to force FAT32 (or use the command line: <code>format /FS:FAT32 H:</code>)
* Formatting with MacOS will only work using the <code>diskutil</code> command line utility. An example usage looks like this: <code>sudo diskutil eraseDisk FAT32 [DiskName] MBRFormat /dev/[DiskNumber]</code>. You can use <code>diskutil list</code> to get the disk number for the SD Card.
* Formatting and partitioning SD cards with Linux can be done using the <code>gnome-disk-utility</code> (known simply as Disks) and is installed on most mainstream distributions of Linux. Disks will access all the drives on the computer so be sure you have the SD card selected when editing. [https://wiki.gnome.org/Apps/Disks Gnome/Disks wiki]
* FAT32 only supports a maximum partition size of 32Gb, on larger cards you will need to create multiple partitions -- however, only the first is recognized by DOS.
* Some folks have had luck formatting cards with the [https://www.sdcard.org/downloads/formatter/sd-memory-card-formatter-for-windows-download/ Official SD Association formatter for Windows].

=== Demos Archive ===

* [https://github.com/FoenixRetro/Documentation/blob/main/f256/archive Download the most recent demos archive] and expand it to the root of the flash card.

=== Debug USB port ===

* This is what most developers use as it's the most convenient. Connect the debug USB port to your PC or Mac

* You can use:

*** A Python script to manage the Foenix series of retro style computers through their USB debug ports. This tool allows uploading files of various formats to system RAM, and displaying memory through various means.

If you have the [[wifi]] configured, you can use [https://github.com/ghackwrench/F256_wget wget] to pull programs and data right off the web!

== SuperBASIC ==

The machine boots to SuperBASIC. SuperBASIC is inspired by BBC BASIC but offers quite a bit more.

=== An informal list of tips, "gotchas": ===

===== IF, THEN, ELSE =====

====== Source of this tip: Ernesto ======
* A regular <code>if then</code> condition can't contain an <code>else</code> statement, as in this example:
<code>10 if a=0 then x=10</code>
* If you need to do an <code>if then else</code> structure, you actually have to do an <code>if else endif</code> structure like in the following example, skipping the <code>then</code> statement.
<code>10 if a=0 
20 x=1 
30 else 
40 x=2 
50 endif</code>
* If you do it in one line it needs to have some colons added, making it look weird like this:
<code>10 if a=0:x=1:else:x=2:endif</code>
* if you dare to omit the <code>endif</code> thinking that the <code>if</code> statement won't need it, (mmm.., everything is in one line, so no need, right?) -Nope...all hell breaks loose!-
<code>10 if a=0:x=1:else:x=2: REM "<-- Error, omited the endif"</code>
* be careful not to add an extra <code>then</code> statement by mistake to an <code>if else endif</code> structure, if you do -All hell breaks loose again!!-
<code>10 if a=0 then : rem "<-- Error, THEN is not needed!!!" 
20 x=1 
30 else 
40 x=2 
50 endif</code>

''Debugging hint: If you encounter an error like "open structure" or "endproc without a proc": do not trust the line number that you are given. The root of the problem is probably in a structure earlier on in the code.''

===== Using procedures =====
The <code>proc</code> keyword is only valid if it appears after an <code>end</code> statement.

===== Keyboard shortcuts =====
