Hey everyone! I'm trying to decrease the clock speed of TIM3 on my STM32L452RET6 (NUCLEO-L452RE) and i've run into issues. I think i figured it out already but I just don't understand why the problem is. My clock tree looks like this in CubeMX:With t...
Can anyone explain to me what is wrong in my code?Microcontroller: STM32C031K6T6I'm trying to make an interface so that the user can change the name of their environment in real time, my idea and what I tried to write is something that holds the prev...
I'm working with an STM32F407G and a SIM7600G GSM module. I've successfully configured the GSM module using AT commands, switched to PPPOS, and obtained a valid IP address, gateway, and netmask using LWIP.I can successfully resolve the IP address of ...
Hi, I’m having trouble reading measurements from the ADXL345 using SPI. I’ve attached a picture from the debugger that shows a view of the variables. The SPI is configured as master full duplex, and I’ve included a screenshot showing the SPI configu...
Hi,I am implementing DFU over I2C to an STM32L476, trying to follow AN4221 and AN2606.For now I am focused on just getting some DFU command to work successfully over I2C, and I started with "Get Version" to get the bootloader version. I am able to ge...
Dear MCD Application Team,in Drivers/STM32G4xx_HAL_Driver/Src/stm32g4xx_hal_uart.c you can find this check:/* Ensure that Frequency clock is in the range [3 * baudrate, 4096 * baudrate] */ if ((lpuart_ker_ck_pres < (3U * huart->Init.BaudRate)) || (lp...
Hi,My uC (STM32F30K6T6) is full in RAM memory.To optimize the RAM size, I have planned to reduce the Heap Size Memory (initial Heap size is 0x400).I do not use any manual memory allocation so, I think I will set it to a quarter of it (0x100), just in...
Gradually debug the DMA send function, HAL-UART Transmit DMA, and find that the function will judge a status bit of the serial port handle, gState. It will only send normally when huart ->gState==HAL UART State READY,And the reason why the first tran...
Hi All I am using STM32L053 board for a product development. I am using RS485 communication Protocol. I am sending Data from Computer to the processor to get the response. When I send the data, I get proper response. but out of 10 times say 1 time t...
It seems that STM32H563MI has four I2C ( I2C1 ~ I2C4):However, the corresponding STM32H563.svd only includes 2 I2C ( I2C1 ~ I2C2).https://stm32-rs.github.io/stm32-rs/STM32H563.html
