SPI DMA Stream Seems to Eventually Freeze

Hi,I'm using CubeMX generated HAL drivers to use SPI in DMA mode. In my particular situation, we are sending a small amount of data (3 bytes) very often over the SPI interface. The data transmission works fine most of the time, but sometimes (as litt...

Hello everyone, I am using stm32f207zg with usb ttl converter with ftdi chip. I want use the usart1 for communication with PA9 e PA10 pins as TX and RX of usart1. I use as virtual terminal, termite, and when i play the program, appear weird characters.

Can I have APB1 and APB2 Timer clock frequencies more than the max that are mentioned in the datasheet?

 I am using STM32F427XX, for which APB1 timer frequency is 84Mhz and APB2 is 168Mhz. Actually per datasheet, max clock frequencies are 45 and 90. My application is running correctly with the above frequencies. Will there be any problem with the MCU u...

Why can not change DBGMCU->CR in STM32F103

I'm use STM32F103C8T6. I use DBGMCU->CR = DBGMCU_CR_TRACE_IOEN to change the value of DBGMCU->CR, but the operation is failed after POR, the register is alway read 0.I suspect that the cause of this problem is the the debug component is not be powere...

obtain the data from camera for cmsis-nn

Hi, I want to do a computer vision application on stm32f407VG discovery board. I have an CNN code with cmsis-nn library. My challange is that Using the camera datas as an input. But i need rgb data as 1 dimentional array. How can save the image in a...

Base on our previous record, JEDEC standard shelf life is 12 months. But recently we received the part STM32F103ZCT6 shelf life is 24 months. Please help to advise on this.

I am trying to implement OpenCAN in STM32H750VIT6, is there any stack or example code available???
