Dear STM experts: I am using the STM32G473RET6 chip for classic mode communication debugging in FDCAN, but there is a phenomenon where I cannot send information. In FDCAN-PSR, I can see an error of LEC being 5. After removing the CAN chip (SN65HV...
Hello guys,I have a stm32G474RET board. I am using tim1 in PWM input mode and i want to update on the fly the hrtimA period and compare values using DMA. This is the code i have written: // Addresses for HRTIM registers (Timer A) destPER = (uint16...
We have a batch of custom boards using the STM32H725IGK3 and have experienced several failures getting started with them as the SWD interface appears to be fried. Initially we thought just bad luck with the first couple (inexperienced engineers or ?)...
Testing a board with STM32U5A5. VDD is 3.3VI have configured one GPIO as input with an external pullup to 3.3V through a 470k ohm resistor.The input reads high, but when I measure the input with a scope, I read 2.2V on the input, which is below 0.7VD...
Hello ST Community teamThe pin F11 on the TFBGA216 figure (figure 4 of the AN4660) should be VDD and not VSS according to the products datasheets (for the STM32F469N and STM32F769Nx6). That should be rectified on the next doc revision. Best Regards.I...
I am trying to apply this configuration to my STM32H757 MCU where I am making a development board. here few things confuses me. 1. I have selected this configuration for better efficiency + noise performance. guide me if I am wrong2. What is the VDD ...
Hi Everybody1) There are some technical o specific reasons, that I was not able to find in the various documentations, to use external SMPS for VDDCORE insted of the internal one ?2) Working on NUCLEO-N675X0-Q, to configure various bridge for interna...
Hi everyone! hope you can help me. I have an issue on the STM32H7A3ZIT6.I already used the BKPRAM on other project, like the STM32H753 and I had no issue, work perfectly.So I don't understand why it is not OK, here below is what I do to test the BKPR...
Heyho,management asked me about a project involving 1 or 2 audio input channels at 32-bit / 200 kHz and - here's my knowledge almost zero - some "heavy & intense" DSP / FFT algorithms for real-time signal evaluation.We're already using the H723 .. H...
Hello everyone.How do I update the firmware via VCP on STM32F407VET6? Is it possible to do so? If so, what needs to be changed and added? Do I have to recreate the bootloader?I don't know where to start here.Thank you :)
