We have all SMT circuit which has BNO055 and STM32F446RET6. Currently our BNO on is not working. All we did was making our GPS module smt in our new version of our circuit and it stopped working. Is it because of our GPS module? Or it can be someth...

I need to achieve fast interrupts because I'm making integration from accelerometer and gyroscope datas in my code. And when I set a timer interrupt frequency to 2.5ms code get stuck. But when I increase timer frequency to 25ms it works just fine. ...

I have Timer 2 interrupt and an UART 4 interrupt for reading from a GPS module. But they don't work with each other. When I disable Timer 2 interrupt UART 4 interrupt starts to work.I did set Timer 2 interrupt preemption priority to 1 and UART 4 int...

I'm new to STM32 development. I need to use RF98W LoRa module and also I need high clock frequency. Problem is RFM98W datasheet says RFM98W has bit rate up to 300 kbps. To achieve 300kbps spi clock frequency I think I need to have low frequency arou...

It turned out we didn't pull reset pin of BNO055 high on the code. Problem solved, thank you for answering.

I actually tried that but I think it prevents me from using my interrupt to full extent. When I read from my sensors in handler I read every 25ms but when I set a flag I read every 200-250ms because my code always waits for lora and sd card modules a...

You're right it turned out my problem wasn't about priority. It turned out I wasn't able to give enough current to my circuit via USB connection. When I connected a external battery it worked.

Sorry, I forgot to mention that. I'm using STM32F446RE
