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...
I am currently using a nucleo g474re board to acquire 10,000 samples from an ADC using a timer and DMA.The timer allows me to use any data rate and the DMA puts the samples into memory without CPU intervention.The process is currently initiated by st...
An application will use two STM-32 MCUs - for purpose of this posting, I'll call them "outer" (it's SWDIO and SWCLK pins can be attached to a STLINK-V2 device for firmware downloading), and "inner" (it's SWDIO and SWCLK pins would be tied to two GPIO...
I have a program where I am trying to scan over 8 ADC channels on ADC1, take 10 samples from each and transfer to the DMA. From everything I have read, I cannot enable DMA Continuous Conversion on STM32F103, so I will need to use discontinuous scan m...
