Ultimate software platform for Microchip PIC24/dsPIC33 MCUs.
- You can use your favorite IDE or editor, as long as it supports CMake
- Tested on CLion and Sublime Text (VSCode users please see this issue)
The PICoBoot USB bootloader
- Updates firmware directly via USB
- No driver installation needed on modern host OS (Linux/macOS/Windows)
fastbootlike command line tool- Non-volatile environment variable (like U-Boot)
- Preinstalled on every PotatoPi PICo24
- Work like STM32 HAL APIs
- Macro based pin configuration
- Supports transferring data in EDS memory regions directly to peripherals
- Supported functions: CDC ACM/ECM/NCM, Mass Storage, Audio, HID and MIDI
- Multiple functions and multiple function instances at the same time (e.g. 4xACM+1xStorage)
- HUB support
- Supported functions: CDC ACM, Mass Storage, Audio, HID and UVC
- malloc can track memory usages, and also allocate in EDS memory regions
- Emulation of Unix APIs such as read/write/sleep/usleep/dprintf
- They can be used to control data flows on UART and USB CDC, and switch RTOS task automatically when I/O is blocked
- FreeRTOS 9.0.0
- LwIP 2.1.1
- Lua 5.1.5
Due to shortage of raw materials of PotatoPi Lite, PotatoPi PICo24 had to be released prematurely to fill the gap. So, not all software features mentioned above are implemented at this moment.
