In my project, my MCU (F411) uses I2C HAL API routinely to read from a sensor device.When some event happens, my interrupt handler will use I2C API to read from different register from that device; so my question is:Is HAL API thread safe? Although I...
I've been having issues with getting an SD card working on an STM32L4R5ZI Nucleo board when using essentially the same code (with minor tweaks) without issues on the STM32WB55 Nucleo board. I've been going through the code of both to determine where...
I have previously used the STM32F103C8T6 is a number of projects and was considering switching to the STM32H503RBT6. My use case is low volume R&D work. With the F1, I would use JTAG for programming but the option isn't available for the H5 in CubeMX...
Hello,I am using an stm32h750. I have an ADC group that includes 4 inputs from GPIO ports and the 3 internal ADCs (VBAT, CPU Temp, Reference Voltage). It's set up with DMA. The conversions run at 150hz.We use a coincell battery voltage as input to VB...
Hi,I have an issue with the CAN1 controller in my MCU. I have connected the CAN transceiver to PA12(TX) and PA11(RX). When connected to the CAN Bus I can see the frames coming to the MCU(RX line) and the ACK bits are visible on the TX line. Unfortuna...
tl;dr: accessing external memory over debugger results in additional unwanted write accesses to adjacent memory locationsI have an FPGA that is accessed via FMC over a 16-bit async connection (16-bit data +15-bit address), sort of like an external SR...
I have a custom board and I have to run an SD card on it using SDIO protocol however on f_mount() function it takes a long time to come out with error FR_DISK_ERR but when I call "HAL_SD_GetCardInfo(&hsd, &sdCardSpace)" then I am getting all the data...
Hello Team,We are considering STM32H562ZIT3QTR MCU for our design. There will be two Microcontroller in our design.MCU consists of one Octal SPI Interface. Can other Microcontroller be interface with STM32H562ZIT3QTR through Octal SPI or we can only ...
主控板 （SMT32F407VGT6）与同服板 （STM32F407VGT6） 之间的CAN通讯，环境温度低于-10度，通讯不正常，环境温度高过-10度！
Dear all,I set up a configuration to send message from ST board to PCAN USB and the other way around. When I send message from board to PCAN, it works just fine. I can see in the PCAN-View screen that the message is received successfully as shown bel...
