I already try for send five byte data in UART DMA. I am using the controller in STM32G030K6T6. Data transmition is working properly but output is did not taken properly. The problem was am transmit data five bytes for UART_DMA but DMA transmit only t...
I'm trying to implement I2C on pins PC6/7of the STM32F446RET, which as I understand can only be used in FMPI2C mode.As such, I'm trying to use the Standard Peripheral Library since the rest of our codebase utilizes it and we do not currently include ...
Hello, i would like to post a problem that i have: i have a custom STM32H755BI (dual core) board that i usually flash with CubeIDE and i debug. Unortunatelly i noticed that the board works fine, but if i reboot the board and i connect with a j-link s...
Hello,I implemented a simple spi transmission on a STM32F469 based board.The problem i'm facing is that the spi function I'm not getting any value in the receive buffer.Trough the oscilloscope i can see the byte being send and the one transmitted bac...
Hello I tried to receive any CAN signal on my device based on STM32F303CCT6. Maybe you have solution :), CAN pins are remapped on PB9 and PB8 pins by STMCubeMX configuratorBelow my code (main.c): https://pastecode.io/s/7av2ge6mand my settings in con...
I have this Nucleo 32 board namely STM32F303K8. I power it externally from 5V pin, so I removed the solder bridge SB9. In this case, the on board embedded ST-LINK is not powered but if first the board is powered then the USB is plugged one can still ...
I would like to set a 1Hz signal on the PC13 (RTC_OUT_CALIB). I have found a manual in document AN3371 (see picture in appendix). The code is also in the appendix. Unfortunately, nothing happens on the PC13 but the RTC works. If anyone has any idea w...
When it is 93, it works normally, but when it is VC, it does not enter uart boot mode.What's the difference?
I'm working on H745 dualcore MCU and I'm trying to get STM32 UID from M4 core accessing to addres 0x1FF1E800UL. Reading datasheet I can't find explanation why that address range is not accessible.
