Hi!I have STM32F469ZGT6 which is having problems with printf function.If I connect debugger probe STLINK-V3SET all my code runs OK.If I disconnect probe my code does not run at all. It does not even start to run.After further investigation, I came to...
Hi ST,We are making product targeting SIL3 safety by using STL library. So, I have few doubts :-1. Is it recommended to have a bootloader in a safety grade product?2. If Yes, then how can I proceed? 3. In normal way bootloader code should be written ...
Hi, I want to implement FOTA in stm32, for that I am reading .bin file and send to the controller through UART. And Write that file to the flash memory, All Ihave done this, but there mismatch data beetween .bin file data written on flash.the readi...
I have just started a project and am using the STM32H743. Is there any reason I should switch to the STM32H753? I know they are pin compatible and the 753 has some more advanced crypto features, but I'm more concerned with availability of these parts...
Need a help to work out the formula. I cant get my head around with this to work out. its polynomial with numerator and denominator. what is the formula for this. Thank you FLOAT_TYPE num_coeff[] = {-2.42580348918581e2l, 4.43575581447635e2l, -8.65706...
I've got the I2S working with DMA as slave receiver, works great, bit perfectly fills receiving buffer,until I restart the master, or introduce noise to I2S bus, then it just loses it, fills buffer with nonsense after that.It's not able to resync to ...
Hi, I want to design a board using STM32F446RET6 MCU. But I have a question about how to properly power the ADC system, and what the VCap_1 pin is. I read that I need to put a 4.7 uF ceramic capacitor with low ESR there. Below is an introductory grap...
Hi,We are planning migrate our product based on STM32G431CBU6 to STM32G474CCU6. Need to make sure they are compatible in hardware design, are the two pin-to-pin compatible?Thanks.
Wich eval board mcu stm32 recommend me to learn and in the future can match with dsp.Regards
Hi All, Been reading and learning a lot about MCU's in general. I'm very very new to all of this so please bare with me.The board comes with STM32F427, and a custom .exe that can flash directly via USB-C. I've read about fake STM32's, and. I'm not su...
