Posted on February 06, 2013 at 15:43Im using a quadrature encoder hooked up to TIM3-CH1/2 and it works fine, counting both edges, up and down. First question is how to read the TIM3-counter values from within a regular (50 us) ISR. Using TIM_GetCoun...

Posted on January 11, 2013 at 11:12Here is a STM32F103-question.TIM2 is using TIM_OCMode_PWM1 and TIM_OPMode_Single (one-pulse mode).Im using TIM2 CH1 for (internal) triggering ADC injected reads using a compare. Im using TIM2 CH2 for (internal) tri...

Posted on February 06, 2013 at 17:12Ok, thanks a lot. If the read is atomic, then I do not have to worry! I did not know this was the case.Anyone having a suggestion on how to use the index-pulse to capture a value on the TIM3 ?

Posted on February 06, 2013 at 16:27If the read is taking 4 cycles, it may not be unlikely that the counter would change during that time. I do not care if the counter is changing just before or directly after my read. It does not matter.Im worried ...

Posted on January 28, 2013 at 06:52You are right. I made some experiments and have confirmed that it is indeed possible to have it working with the PA0/PA1 as analog inputs if they are not hooked up to the timer in the way you suggest.
