STM32L476RET JTAG TAP Chain failed when unsued pin connect as analog ?
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...
Resolved! A 16bit unique ID of MCU
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...
ISR with debugger doesn't work when N_RST not wired (SWD) on STM32F0
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...
How to setup USART to read unknown string lengths.
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 ...
Switching MSI to HSI on STM32L1
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...
Errors in HAL SMBus driver for STM32F4 ?
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...
How to differentiate between receive interrupt and transmit interrupt in UART ?
How to differentiate recieve and transmit interrupt of UART using HAL library , low level library and directly accessing registers ?which HAL lib function will check this?
Errors while trying to port a C++ library
I'm trying to import an Arduino C++ library into an STM32F4 project. I set the project to be a C++ one while I was creating it. I've also made the necessary code changes needed for the STM32. However, while compiling I'm getting the following errors....
