A proof-of-concept FT2232D emulation firmware for an STM32F042 microcontroller.
Warning: this project is not finished yet, lots of FTDI commands are not implemented.
| FTDI signal | STM32 pin |
|---|---|
| ADBUS0 (TCK) | PA5 |
| ADBUS1 (TDI) | PA7 |
| ADBUS2 (TDO) | PA6 |
| ADBUS3 (TMS) | PA4 |
| BDBUS0 (TXD) | PA2 |
| BDBUS1 (RXD) | PA3 |
| USBDP | PA12 |
| USBDM | PA11 |
Additionally, 12MHz clock is provided on PA1.
You will need a NUCLEO-F042K6 board to run the firmware.
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
Install cargo-embed:
cargo install cargo-embed
Clone the repository:
git clone https://github.com/Disasm/f042-ftdi
cd f042-ftdi
Connect your NUCLEO-F042K6 with a USB cable.
Build and run the firmware:
cargo embed --release
