Blink_cpp_LL

  • Simple project that blinks the Nucleo's LED based on the push button.
  • It's a CPP project (CubeMX generates .C code by default) and used LL rather than HAL. I'm finding that LL (Low Level) is simpler.

ctr_isr_cpp_LL

  • Uses TIM2 to count a push-button connected between PA0 (called TIM2_ETR) and 3V3.
  • PA0 is configured with a pull down.
  • Green LED blinks but the blink rate toggles upon each TIM2 interrupt.
  • TIM2 interrupt is called after 5 button presses.
  • To debounce the button, LL_TIM_ETR_FILTER_FDIV32_N8 is used.
  • No HAL - all LL (Low Level).

uart_ll_polled

  • echos UART2 to the ST-Link USB Serial port.
  • Uses polled mode with about 3 low-level APIs.
