Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
If I generate a 2kHz interrupt process using a basic timer and perform several SPI communications with DMA during that cycle, the generation of the 2kHz interrupt process is delayed by roughly the interrupt time in DMA.Can you please provide a soluti...
HiI have a custom board with an EMMC connected STM32F446.My write access to EMMC for 16 kbytes is quite fast (2-3 ms). EMMC during the write operation consumes some 50 milli ampere more than during the its idle state. This would be fine, but as far a...
We have been building boards for years using the STM32F407ZET6. Our system uses a USART bootloader from a host processor running Android that uses stm32ld to do the bootloading. It has worked pretty much flawlessly for years. Recently we started rece...
Hello, I am currently working on a project where I need to configure a NUCLEO F411RE Board as an I2C slave. It will be connected to a Raspberry Pi Master. I am able to detect the NUCLEO on the raspberry Pi, however I am unsure how to get the read by...
Good morning everyone,I have an application where a STM32G474 as SPI master interacts with another ST controller as SPI slave. These are full-duplex DMA transfers of about 500 bytes at 10MBit transfer rate. The slave signals that it is alive via a di...
The system consists of three modules: a 4G module, a GNSS module, and an STM32 processor, with the modules connected to the STM32 via UART. In terms of program functionality, the STM32 needs to implement data forwarding and saving. It receives data ...
I went through the following documentation available from STM on FDCAN bootloader:AN5405 - FDCAN protocol used in the STM32 bootloaderAN2606 - STM32 microcontroller system memory boot moderm0468 - Reference manualJump to bootloader code used: (Refere...
Facing problem with run UART interrupt when receiving data.In that case I'm getting data but most of lost and receiving after some delay.If anyone solved this kind of problem than help me for this.
Hi team,Can you help for resolve the below PWM generation issue,we are using STM32H7A3ZIT6 controller, in that for the PWM generation configured Advanced Timer 1 with the below configuration and we are getting the PWM wave like below pic. But we need...
Say that HAL_UART_Transmit function is concurrently called by two tasks.So far, I know such a function is blocking, but I am not 100% sure that because of that it shall not be locked before usage if a concurrent task is going to call it.
