An IDE and interpreter of Brainfk++ for Arduino boards. Try it out in Wokwi (🌐Web-based simulator).
Brainfk++ is a low-level programming language comprised of 22 instructions, with each instruction represented by an ASCII character. It expands on the work of Urban Müller by introducing more instructions, thereby allowing you to easily work with a large amount of data and interface with various I/O.
| Instruction | Description | Parameters |
|---|---|---|
| + | Increment current cell value by 1. | - |
| - | Decrement current cell value by 1. | - |
| < | Move cell pointer left by 1 cell. | - |
| > | Move cell pointer right by 1 cell. | - |
| [ | If currentCellValue == 0, goto cell after corresponding ']' instruction. | currentCellValue |
| ] | If currentCellValue != 0, goto cell after corresponding '[' instruction. | currentCellValue |
| , | Take input and set current and following cells to either (left, right, up, down, enter) (mode == 0) or (analogInput1, analogInput2, enter) (mode == 1). | mode |
| . | Output currentCellValue as an integer (mode == 0), character (mode == 1), or custom character (mode == 2) at character (x, y) on display, or clear the display (mode == 3). | currentCellValue, mode, x, y |
| ? | Set the value of the current cell to a random integer from 0 to maximumIntegerValue. | maximumIntegerValue |
| ! | Play a tone with a note value of note and a duration of (duration / 10) seconds. | note, duration |
| : | Output currentCellValue as an integer (mode == 0), character (mode == 1), or custom character (mode == 2) over serial, output additionalValue as an integer over serial, and wait for response (integer, character, or input) (expectResponse == 1). | currentCellValue, mode, additionalValue, expectResponse |
| ~ | Pause for (duration / 10) seconds. | duration |
| ^ | Set the cell pointer to currentCellValue. | currentCellValue |
| = | Set the value of current cell to value of cell at cellIndexNumber. | cellIndexNumber |
| # | Set the value of the current cell to either 0 (currentCellValue != 0) or 1 (currentCellValue == 0). | currentCellValue |
| ▏ | Set the value of the current cell to either 0 (currentCellValue < 0) or 1 (currentCellValue > -1). | currentCellValue |
| @ | If global PIN has been set and is correct, execute program at programIndexNumber. | programIndexNumber |
| * | Concatenate cell array and program arrays (mode == 0) or do not clear cell memory when program is finished (mode == 1). | mode |
| ; | Set the value of the buffer cell to currentCellValue. | currentCellValue |
| _ | Set the value of the current cell to the value of the buffer cell. | - |
| & | Set the value of the current cell to (currentCellValue * 2) (a.k.a. a bit shift). | currentCellValue |
| " | Skip the next instruction. | - |
| Error | Description |
|---|---|
| 1 | Minimum of cell memory reached. |
| 2 | Maxiumum of cell memory reached. |
| 3 | Corresponding ']' instruction not found. |
| 4 | Corresponding '[' instruction not found. |
| 5 | Invalid character value. |
| 6 | Invalid note value. |
| 7 | Invalid program index value. |
| 8 | Access denied. |
