STM32C0 RM0490 Rev 3 typo/bug: GPIOA_MODER reset value is not 0xEBFF FFFF
Hi,I'm observing GPIOA_MODER reset value 0x2BFF FFFF on my STM32C0116-DK, not 0xEBFF FFFF as written in the RM.My guess: because PA15 does not exist on that MCU hthKnarfB

How to use different CRCpolynomials for SPI Tx and SPI Rx?
I am using SPI CRC feature of STM32H563ZI.My ST Master must transmit an 8 bit CRC with a polynomial 0x07.It receives a 16 bit CRC from the slave (a different hardware). The ST Master must now compute a 16 bit CRC with polynomial 0x11021 and verify th...
FMC SRAM not working
Hello,We have been using two SRAMs (CY7C1061G30-10BV1XE) & one NAND Flash(MT29F8G08ADAFAH4-AAT) interfaced with STM32L562 micro-controller on same FMC bus. We have initialised FMC and try to access SRAM1 by selecting Chip select: NE1 and Bank 1. It i...
Resolved! Running HAL_SPI_TransmitReceive causes reset of the STM32L151RBT6A
Hi. First time I have posted here. This problem is driving me nuts, so hopefully someone might lead me to a solution. I am under extreme time pressure with this project and need to solve this very quickly. If anyone can help, it would be much appreci...
Resolved! Portability of the code STM32F411
Hi,I have built a program on my Nucleo F411 development kit, which has an STM32F411RE on it. I want to design a custom PCB for my program and use the same STM32F411, but this time in an STM32F411CE format.Using STM32CubeIDE, would it be possible to ...
STM32L452xx Bootloader on UART4
I'm looking at AN2606, section 65.1 and it looks like UART 4 can NOT be used by the bootloader to load FW into the part. Can someone confirm that is true?
I3C error in transmission/reception process - NUCLEO-H563ZI
I am using 2 Nucleo-H563ZI boards, one as controller and the other target, and referencing the knowledge base post "How to set up and run the I3C_Private_Command_IT controller and target example projects" yet I am getting an error. From what I can te...
Resolved! Núcleo-H755zi spi with NRF24L01
I'm trying to use Núcleo H7 spi 1 to send a message via radio with NRF24L01, the code using HAL worked perfectly on an Stm32F103 but when i try adapting it to the Núcleo it just don't work. Can somebody help me up? The SPI clock is 100MHz , the core ...
nRF24L01 transmitting only 10-15 times per second, and the data is multiplied by two
I'm trying to write a driver for the nRF24L01+PA+LNA. I am using STM32F103, and on the receiver side I have an ESP32 with Arduino IDE and the RF24 library. To rule out a hardware issue I have programmed the STM32 using the Arduino IDE and library and...
STM32H7 SPI6 not working with DMA
Hello team, We have another challenge with STM32h725 controller, What I am trying to do and achieve is, Setup few external ADC over SPI bus with DMA. The ADC on SPIs other than SPI6 works perfectly. But the SPI6 is not with regular DMA but with BDMA....
