Hello STM32G0B1 For some obscure reason, sometimes the systick handler function is not called anymore.I mean, it works for some time then it does not work anymore. It looks like it is more likely to happen when I'm debugging but I have no factual inf...

Hello, With stm32G0, I can capture a pwm frequency and duty cycle using this configuration:DMA : Now, for pinout reasons, I want to do the same thing using channels 3 and 4 instead of channels 1 and 2 but I can't find a correct set of settings.On pa...

Hello, Can I say that "IDLE" is equivalent to "RTO with 8-10 bits (depending on framing)"?Or are there some other subtle differences? My goal is to transfer received data with DMA and start interpretation of the data when nothing is received on the l...

Hello, I try to add MSC feature to my app. MCU is L452.To avoid side effects, I started a brand new app with cubeIDE/Mx.I activated USB_DEVICE feature.I declared the USB_DEVICE as mass storage class.I had a look to the MSC_standalone example from G0 ...

Hello, I'm experimenting with algobuilder, motionFX and IKS01A3 + SMK1229AAA.Btw, very cool app for investigation.My goal is to obtain vertical speed. As motionFX provide gravity vector with magnitude 1 (let's call it G) and linear acceleration vecto...

1- Not that much happens in systick_handler in fact, calls are more or less setting a boolean and sometime a 10µs call...2- Yes :

It finally happened!

Ok, Thanks. It took some time to reproduce.As you can see on this new screenshot : - There's a breakpoint in the systick interrupt. after some time, the system never stop on it (and the related code is not called, so it's not a breakpoint issue).- I ...

Thanks for your answer, it's exactly what my experiments lead me to understand.Delay is the only difference between RTO and IDLE.

Hi Miroslav, Thanks for you answer.I'm looking for a solution much more faster than VC.I did many attemps with differents strategies or sensors and I'm not far to conclude that it is not possible today... :( thanks again.Julien
