< | The board support package for the STM32WB Nucleo Board is restricted to the Arduino UNO R3 pin header and the onboard LEDs and switches (buttons). The STM32 has much more capabilities then 14 digital I/O pins, 6 analog input pins, UART, SPI, and I2C interfaces. But if you want to use the more advanced features you can use the CubeMX to create source code for the internal peripherals. This project wants to show how to use the Cube Ecosystem for a Forth system (or vice versa) and can't implement all features and possibilities the STM32WB has. It is a good starting point for your project. |
