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 pcntModeExtSingle modes.
◆ filter
| bool PCNT_Init_TypeDef::filter |
Enable filter, only available in pcntModeOvsSingle* mode.
