Hello,The problem is that we have made 50 customized boards using STM32F412RET6TR, 2 of them has the same issue. It does not run the code (forzen) at cold start up, but will work after a manual reset or power unstable.One Device was fixed by replacin...
I'm trying to learn how to use the LCD display on the STM32H745I-DISCO board.(I'm a beginner at coding, so please go easy on me!) Right now, I'm just trying to display basic text on the screen, but nothing shows up, it's either all white or all black...
I'm trying to implement a serial bit-stream input (PCM-style) on an STM32U575. I have set up an EXTI channel to capture the incoming clock signal and then I'm using the following code in the ISR to capture the data bits:__attribute__ ((section(".RamF...
Hello everyone,I'm currently working with an STM32F746 microcontroller as an SPI slave using DMA for data reception.The SPI master sends fixed-size packets of 512 bytes, and everything works fine most of the time. However, occasionally, a few bytes (...
Hi Team,We are currently working on a design using the STM32U5A5QJI6Q microcontroller in a BGA package, implemented on a 4-layer PCB. During the hardware development phase, we inadvertently omitted the external pull-up resistors on the I2C lines, spe...
Hello, I am having an issue implementing a 32 bit CRC 0x04CDB117I am quite confused by the documentation on how to set the a 32 bit CRCI don't understand section 53.5.3 on the most significant bit in in CRCPOLY must be larger than the data size.I don...
I have designed a PCB that uses the STM32L433RCT6P which is the same processor used on the NUCLEO-L433RC-P board.However, I am not using the external SMPS on the PCB I have designed.I put up a post asking what I should do with the VDD12 pins if I don...
Hello, I'm using a STM32L071KZT6 on a custom PCB and it was working fine, until after some programming iterations, it suddendly started drawing more current than expected. It reached 220mA to power with 3.3V. This happened twice, in two different mc...
The DBATTEN setting in the UCPD_CR register claims the following But as far as I know, the dead battery functionality is always present. It would have to be to work unless this is stored in NVM.Maybe this DBATTEN is some other Rd value? Maybe the ANA...
What is the maximum current that the STM32 GPIO can withstand when set to open-drain mode and the NMOS is on without getting damaged?
