writePWM
void writePWM(optVAL_t val)
write a clamped pwm value to an output pin
checkIdx
void checkIdx(optVAL_t idx)
[DEBUG_MODE] used to check if a pin index is in bounds
setPin
void setPin(optVAL_t idx, optVAL_t mode=OUTPUT)
[COPY&PASTE] set a pin to a certain mode => checkPin() will return true then
writePin
void writePin(optVAL_t idx, bool val)
write a boolean state to an output pin
_pwmValue
optVAL_t _pwmValue
Definition: eagle_PinCtrl.h:21
readPin
optVAL_t readPin(optVAL_t idx, bool dig=true)
read a digital state from an INPUTpin
_OpwmValue
optVAL_t _OpwmValue
Definition: eagle_PinCtrl.h:21
shiftSingle
void shiftSingle(optVAL_t idx, bool val)
[SHIFT] Changes a single output Pin
optVAL_t
