I am designing a motor controller using STM32G030c8t6. but while connecting it to battery, if positive terminal gets connected to the battery before the negative terminal, then a voltage spike (of the voltage of battery) occurs on the board and it ap...
Hi AllI want write on the SDMMC using HAL_SD_WriteBlocks_DMA system call. The function itself works, the sector on the SD is written, but no callback function (HAL_SD_TxCpltCallback) is called.Did someone experienced such trouble ?Thanks
Hi,I would like to know what is max number of SPI slaves I can connect to a single SPI bus of STM32F779? I understand that using the chip select pin I can select respective slaves to operate. But is ther eany recommendation from ST that ideally , I s...
Hello Experts,I am having problem with uart on stm32h755, nucleo kit.I use uart1 and uart2 to communicate with each other using DMA.When I set the baud rate above 1M baud rate it doesn't work. Below is the clock configuration.And here is the UART con...
Hi i m using STM32H750XBH and i would like to remap SPI pin to the following pin out, i m using SPI3 full duplex master, HW NSS output, could anyone advise is this is feasible? Or i need to following the pin out from the standard H750 ioc pin arrange...
I'm bringing up a new board using a STM32H7A3. I've developed, downloaded, debugged and run lots of test programs from the VisualGDB IDE. Now I'm working on the main application. I can still develop, download, debug and run from VisualGDB but when I...
I have a question, how do I get the '.ld' link file for Flash, compared to the cmsis_device_f1 library cmsis_device_f4/Source/Templates/gcc/ directory that doesn't contain a `linker/` folder.

Hi friends from community. I have a question about the paragraph about DMA section from STM32F0x1 reference manual page 200, as showed below:I don't know how to understand the red highlight part of above picture,why there says <these ‘memory’ registe...
The schemes of a production circuit are given to me from another designer for being analyised. PCB board is a STM32F103VC based circuit.When I was looking at the bootloader circuitry scheme I saw how RS232 bus seems to be connected to the UART1 micro...
