Hi there.I have been trying to configure this USART6 on my STM32F401RE board as 9600 and Async.But I just can't seem to figure out what I am doing wrong? I am not using the HAL for this project.I really just want to get an example of how to use the U...
Hello everyone!I am trying to copy RAM data to FLASH. I am using STM32L412KB evaluation module. I have made a USB of my own. I am able to talk over the USB. It's a 34Kb mass storage device. I can make a .txt file and store it but, every time I connec...
Hi,I work on custom board with STM32 chained with SAMAD2 processor on JTAG.Architecture is that below :JTAG_TDI -> SAMA5D2 TDI -> SAMA5D2 TDO -> STM32 TDI (PA15) -> STM32 TDO (PB3) -> JTAG TDOThis work fine when STM32 is empty (no code) or when I dis...
I need a unique 16bit ID for each device. I know the device ID is unique but it is 96bits. I'm not sure if different parts of the 96bit point to specific characteristics or the whole 96bits are made random? To be more specific, I want to know what 16...
Hello,I'm facing a problem that I can't explain. In most of my devices, the SWD connector is completely wired (ca. VCC/GND/SWDIO/SWCLK/NRST), and I never had any problem to debug those devices with SystemWorkbench and a STLINK-2 debugger.One of my de...
I'm using a NUCLEO-L053R8 board. I have tried a variety of USART settings including interrupt and DMA, but cannot reliably read unknown string lengths (at 115200 baud).I want to read either until a certain character is seen, or for a specific period ...
Hi,I have a problem: in my soft, initial setup is for MSI mode (this because, in "stop mode" it will return in this mode) but I want to choose STM32L1 mode, in MSI mode (2.097Mhz) or in HSI (16Mhz) mode When I select HSI mode (after initial MSI setup...
HelloII've been working on Host SMBus mode using STM32F417 and HAL F4 version 1.25. When debugging errors on bus I found next code in function SMBUS_MasterTransmit_BTF (file stm32f4xx_hal_smbus.c line 2020)./* Call TxCpltCallback() directly if no...
