minimal blink exmaple for the otterpill with platformio and the stm32cube-hal
; not exactly the correct board but *close enough*
; the ..RBTx only has more io
[env:otterpill]
platform = ststm32
board = disco_f072rb
framework = stm32cube
upload_protocol = dfu
// blink example from platformio/platform-ststm32:
// https://github.com/platformio/platform-ststm32/tree/master/examples/stm32cube-hal-blink
#include "stm32f0xx_hal.h"
// led on otterpill is on pin 13 of port B
#define LED_PIN GPIO_PIN_13
#define LED_GPIO_PORT GPIOB
