I set up channel 1 and channel 2 of the TIM2 timer for input capture. As soon the execution jumps into the interrupt handler "HAL_TIM_IC_CaptureCallback" (and stop on breakpoint at line 3) I can see the right values for SR in the debugger's SFRs window. So, the UIF-flag is set and CC1IF and/or CC1IF. hornswoggle leprechaun origins

TIM2 overflow does not trigger TIM2_IRQHandler @ STM32G031J6. With the following code I want to make pin 5 (PA11) of an STM32G031J6M6 blink at 50 kHz. To do this, I configured TIM2 to overflow every 10 us. This is to call an ISR ("TIM2_IRGHandler") that toggles the level of PA11.

Frequency = Fclk (timer) / (prescaler + 1) For example, you chose prescaler = 0, it implies that your timer finishes counting [0: count) in a period of 1 / 80MHz, in case the SystemClock is configured like this (you should check the value of the clock and the prescaler to ...

I didn't check all of your code, but it seems your ISR is missing. The name of the ISR which is defined in startup_stm32fxxxxxxx.s file (which is vendor supplied) should match exactly with the function name you define in the C code.

Web20 mar 2014 · The idea to create 16 individual data streams is the following: 1. Have a Timer (TIM2) run at 800kHz and configure the compare modules so that there is a match on the low bit time after ~375ns (CC1) and the high bit time after ~700ns (CC2). 2. Use three DMA streams to control the output data register of an IO bank and set the IOs appropriately.

It's actually short and easy, albeit a little confusing at first. The problem with the interrupt is that it operates outside the scope of your polling function.

Webon many STM32 chips, certain timers can act as both master and slaves. As such, it is possible to chain more than 2 timers together to form 48bit composite timers (3 x 16-bit timers), or 64bit composite timers (4 x 16-bit timers). or even more.
