KNXduino library for KNXduino project

• See hardware and instructions
• Only STM32G0 MCUs are supported. This library will not work with Arduino Uno and other non-STM32 boards!

Hardwired pin-mappings

• For KNXduino One Board = KNXDUINO_ONE_PINMAPPING
  • PA0 (COMP1_OUT) - connect to PA2 (TIM15_CH1)
  • PA1 (COMP1_INP) - KNX_RX_AN (bus voltage/34)
  • PA2 (TIM15_CH1)
  • PA3 (TIM15_CH2) - KNX_TX
  • PA9 (USART1_TX) - Debug UART (Serial) TX
  • PA10 (USART1_RX) - Debug UART (Serial) RX
• For NUCLEO-G071RB Board = KNXDUINO_NUCLEO_PINMAPPING
  • PA0 (COMP1_OUT) - connect to PC1 (TIM15_CH1)
  • PA1 (COMP1_INP) - KNX_RX_AN (bus voltage/34)
  • PC1 (TIM15_CH1)
  • PC2 (TIM15_CH2) - KNX_TX
  • PA2 (USART2_TX) - Debug UART (Serial) TX
  • PA3 (USART2_RX) - Debug UART (Serial) RX
