Chronometer for downhill competitions

Pinout

  • PA11/12 - USB

  • PA9(Tx),PA10 (debug mode) - USART1 - debug console

  • PA2(Tx), PA3 - USART2 - GPS

  • PB10(Tx), PB11 - USART3 - LIDAR - TRIG3

  • PA1 - PPS signal from GPS (EXTI)

  • PA4 - TRIG2 - 12V trigger (EXTI)

  • PA13 - TRIG0 - button0 (EXTI)

  • PA14 - TRIG1 - button1/laser/etc (EXTI)

  • PA15 - USB pullup

  • PB8, PB9 - onboard LEDs (0/1)

  • PC13 - buzzer

LEDS

  • LED0 - shining when there's no PPS signal, fades for 0.25s on PPS
  • LED1 - don't shines if no GPS found, shines when time not valid, blinks when time valid

Not implemented yet:

  • PA5,6,7 (SCK, MISO, MOSI) - SPI
  • PB0 - TRIG4 - ADC channel 8
  • PB6/7 (SCL, SDA) - I2C
