Project overview using the MCU:
- CPU clock: 1 MHz
- Peripherals used:
- Timer6:
- Timer6 is configured
to overflow with 1.5 ms timer period and is used as CLC clock
- CLC1, CLC2, CLC3, CLC4, and
CLC5:
- CLC3 and CLC1 are
used together for onboard button S2 debouncing control
- CLC4 and CLC2 are
used together for external rotary encoder debouncing control
- CLC5 is used to
extend the 2-CLCs solution (CLC3 and CLC1) to 3-CLCs solution
- GPIO:
- pin RC5: CLCIN0 input
signal, connected to the onboard S2 button by default
- pin RB2: CLCIN2 input
signal, manually connect it to the external rotary encoder
- pin RA4: D2 LED
output
- pin RA5: D3 LED
output
- pin RA6: D4 LED
output
- pin RA7: D5 LED
output
