Field Documentation
◆ mode
| PCNT_Mode_TypeDef PCNT_Init_TypeDef::mode |
Mode to operate in.
◆ counter
| uint32_t PCNT_Init_TypeDef::counter |
Initial counter value (refer to reference manual for max value allowed).
Only used for pcntModeOvsSingle (and possibly pcntModeDisable ) modes. If using pcntModeExtSingle or pcntModeExtQuad modes, counter value is reset to HW reset value.
◆ top
| uint32_t PCNT_Init_TypeDef::top |
Initial top value (refer to reference manual for max value allowed).
Only used for pcntModeOvsSingle (and possibly pcntModeDisable ) modes. If using pcntModeExtSingle or pcntModeExtQuad modes, top value is reset to HW reset value.
◆ negEdge
| bool PCNT_Init_TypeDef::negEdge |
Polarity of incoming edge.
- pcntModeExtSingle mode - if false, positive edges are counted, otherwise negative edges.
- pcntModeExtQuad mode - if true, counting direction is inverted.
◆ countDown
| bool PCNT_Init_TypeDef::countDown |
Counting direction, only applicable for pcntModeOvsSingle and
