//! title: A board echoes its UART, reads a sensor and the ADC, and lights an LED while a button is up
|
|
//! description: Every embedded widget but PWM, as the board generator's own tests have them (codegen::board's io graph): the UART echoes up to 8 bytes, an I2C sensor at address 72 feeds an SPI transfer, the ADC and the interval timer run, and pin 11 is driven to the opposite of pin 10, high when anything fails. Exported with flowrsc firmware for the Nucleo-F401RE or the Pico.
