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
