Hello,I am using the NUCLEO-WBA55CG. I read in the Reference manual (https://www.st.com/resource/en/reference_manual/rm0493-multiprotocol-wireless-bluetooth-le-and-ieee802154-stm32wba5xxx-armbased-32bit-mcus-stmicroelectronics.pdf) that the SPI perip...
Dear STMicroelectronics Support, I am working with the STM32H723ZG-E01 board (Serial: A230801274) and encountering an issue where CAN communication is not functioning as expected. Based on the documentation, I have configured the FDCAN1 interface to ...
Hi,The STM32H7RSxx TRM specifies, for ETH_MACMDIOAR, the following CSR values: Bits 11:8 CR[3:0]: CSR Clock RangeThe CSR Clock Range selection determines the frequency of the MDC clock according tothe CSR clock frequency (eth_hclk):0000: MDC clock ...
I have the following function to verify that a full flash sector is erased but the code never seems to exit this function and I believe it gets stuck at the point where I dereference the address value. What could be the issue?static bool check_sector...
Hello,I am trying to implement Modbus protocol in an efficient way. Untill now I have implemented everhting with UART interuot based Transmission and recption. Now I would like to implement with DMA to offload controller from much neavy lifting. For ...
I'm using STM32CubeMX to generate initialization code for all my hardware. I initially tried USART1 TX with GPDMA1 Channel 0 - all data was transmitted over TX except neither the GPDMA1_Channel0_IRQHandler() nor the USART1_IRQHandler() didn't trigger...
Hi all,I'm working on a very low power custom board powered by a STM32C011D6Y micro controller. I must read an ADC input routed to F1 ball (PA3, PA4, PA5 or PA6) but I'm measuring some strange power consumption related to the input voltage on the pin...
I wanted to use the HDP (Hardware Debug Port) peripheral on the STM32N6 MCU (Nucleo N6 board), but CubeMX does not generate the MX_HDP_Init() function for it and does not initialize the peripheral either.Based on the reference manual, I tried configu...
The new revision of errata sheet for STM32H7 mentions a new error relative to SPI: It is particularly vague.What "fast software" and "slow SPI" frequency means exactly ? What is the minimum ration between both frequencies to avoid the issue ?What "ad...
Hello,Trying to achieve wakeup system at every 60 sec or more using LPTIMER1 in STOP2 mode.Observation:1. STOP2 = enable and LPTIMER = 60 sec --> Wakeup not work2. STOP2 = disable and LPTIMER = 60 sec --> Wakeup work3. STOP2 = enable and LPTIMER = 2 ...
