Posted on July 26, 2017 at 02:59Cannot get it to fire the IC Capture interrupt, and the macro that decodes the PWM Pulse finished interrupt might be broken becuase all running timers seem to be sent a handle to that callback. htim->Instance TIM2 gets a callback, when i tried.
LED shows the PWM ringing away from TIM1 but TIM2 never gets the IC Capture callback
STM32CubeMX 4.22
STM32Cube_F1_1.6
Timer 1:
prescaler 7199
period 9999
pulse 5
Output to pin PA11
Timer 2:
prescaler 0
period 65535
input TI1FP1 on PA0
The CubeMX application generates:
/**TIM2 GPIO Configuration
PA0-WKUP ------> TIM2_CH1
*/
GPIO_InitStruct.Pin = GPIO_PIN_0;
GPIO_InitStruct.Mode = GPIO_MODE_INPUT;
GPIO_InitStruct.Pull = GPIO_NOPULL;
and GPIO_MODE_AF_INPUT is the same as MODE_INPUT
DIER is set for interrupt on CC1IE and CC2IE
can't get CCR1 to set
