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...
Hello ST Community,I am currently working with the STM32L433RC microcontroller and I am exploring the possibility of utilizing USB 2.0 in Host mode for my application. I am seeking guidance on the respective topic.
Hallo,I want to update MASTER CMP1 over DMA and the others TIM_x on MASTER-update.New values of CMPx registry are calculated in SysTick_Handler() and should be updated at once.The problem is: MASTER update on DMA does not work.Could anyone please loo...
