We connected STM32F051 to ASM330 over SPI . The communication works Chip select as a GPIO line the SPI is not able to correctly toggle the Chip select . There is a 10K ohm Pull-Up resistor on the Chip Select Line between STM and ASM . Is this correct ?

Need help with PN532 via HSU to STM32F405

I need help with to access the pn532 nfc to stm32f405 via HSU. i have looked many references but some of them are in i2c. And i need help with HSU way, please help anyone

Resolved! I use a STM32F469. I had a program to erase and write in the flash. Since I switched the sysclock from 80MHz to 100MHz, it doesn’t work anymore. I use HAL functions to erase and write to the flash. Do you have any idea what can cause this problem? Thanks

STM32F767 QSPI vs FMC

Hi Community!For a new project I need both external RAM and externalFLASH memory (from which code should also be executed) on aSTM32F767BG.Now I'm faced with the question of what makes more sense:• SRAM on FMC and Flash on QPSI• Or SRAM and Flash bot...

How to use backup registers without setting up RTC ?

Hello,I have a question: I want to use the backup registers to recover data after waking up from standby. Is it possible using it without setting up RTC or are they bound to RTC ?If they are related and setting up RTC is mandatory prior to use the re...

How To use software NSS using SPI DMA with STM32G474

I'm using STM32G474 and I want to use SPI DMA with ltc2344-16 (ADC chip)I can send and receive data through SPI using below codes. (LL) void ADC_RECEIVE(uint8_t data_in) { uint16_t registor = 0; uint16_t part[6]= {0,0,0,0,0,0}; if(data_in == 0) ...

Resolved! Hi, I wonder if the "newer" STM32H7 NUCLEO boards (e.g. NUCLEO-H723ZG) still have the male pins on the bottom side? In the pictures I found its not really visible. My NUCLEO-F767ZI board has female sockets on top side and male pins on bottom side.
