A BrainF interpreter and native compiler written in C for the TI 84+ CE calculators. The bytecode compiler and interpreter work on any system. The native code only compiles to ez80.
Huge thanks to MateoConLechuga for the toolchain and all the work on the CE calculator. Thanks also to Iambian over on the cemetech irc.

- Download and install https://github.com/CE-Programming/toolchain/releases
- Download or clone this repository
- Navigate to the BrainFCE directory in a command prompt/terminal
- Type 'make' without quotes.
- BRAINF.8xp will be in the bin directory.
- Download the latest release at https://github.com/nathanfarlow/BrainFCE/releases
- Send BRAINF.8xp to your calculator.
- Download libraries from https://github.com/CE-Programming/libraries/releases and send them to your calculator.
- Run BrainFCE with Asm(prgmBRAINF
- Use arrow keys and select your program and either run with bytecode or native.
I've already packed the fractal, hello world, and xmas programs as .8xp files in the releases. You can just send these to your calculator and run with BrainFCE.
- Create a TI BASIC program on your calculator like usual.
- Fill it with BrainF instead.
- Open BrainFCE and select the program and run.
- Download and install TI-Connect CE.
- Click Program Editor
- Click New Program
- Paste BrainF code
- Change VAR NAME
- Ctrl+s and save as a file
- Send file to calculator
- Open BrainFCE
- Select and run program
Bytecode with the 'mode to stop bytecode' option enabled is recommended until your program is perfected. This prevents infinite loops in case your BrainF code has a bug and loops infinitely. Simply press the mode button to stop the bytecode execution as long as the checkbox is selected.
Once your program is perfected you can run it natively. There will be no interrupts, so if you want to stop the execution you will have to clear your ram... (I take no responsibility) Native execution runs exponentially faster than bytecode on BrainF programs with lots of calculations such as the fractal program. The fractal program takes ~60 minutes to complete on a normal calculator when using optimized native.
The optimize checkbox is recommended and will increase speeds with both the bytecode and native as well as shrink the produced code without changing any of the code's original functionality.
You can input up to 13 characters in the input box; press alpha to access letters. Press delete to delete one character or clear to clear the whole textbox.
Press the mode button to quit the application. Press the clear button to exit the console when the BrainF program has finished.
BrainFCE can run both archived and unarhived programs without an issue.
The max stack depth for leading opening brackets is 100.
The max program size is 12000 characters.
The max native instrucitons is 36000.
The max bytecode instructions is 9000.
You will get an error printed to the console if any of these are exceeded.
The console window has dimensions of 50x150
