Hi guys.I am using STM32F401VEH6 to read the peak value of a waveform like sinewave.but the value drifts about 40LSB time to time.I connected VDDA to Vref+ and seperated from VDD.(based on Application Note recomandation)But when I checked the datashe...
Hello,I am using the STM32F756ZGT6 for an upcoming project. I am using a 480x272 resolution display (RGB565) with a single layer. I also have additional features that will be on this board that use more RAM (2 tasks, multiple variables, etc.) that a...
I am trying to set up a dual boot system using a bootloader in stm32F7 without using the dual bank operation. I have the bootloader, which can flash the bin files directly to the flash .My concern is whether .bin files contain any address information...
Does anyone know the best way to implement a statechart or statemachine in C? Are there specific libraries required or should I consider just using simple statemachine tables with switch statements? Maybe statechart is overkill for my app and using...
Hello,I'm trying to do a basic spi master transmit, and am having issues with the MOSI pin output. It seems the value is getting written, but the voltage swing is ~200mV rather than full value. I suspect I have the GPIO pin mis-configured, but I'm at...
I have written a code to receive UART data in DMA interrupt mode using circular buffer and configured timer 6 and timer 7 for doing other tasks in the same code. The problem I am facing is that I am not getting UART data and neither timer interrupts ...
I'm working with the STM32F446-microcontroller and once in a while after power-up the microcontroller is unable to drive pin PA0 high or low and I also suspect that it can't drive PA8, configured as an I2C-clock, either when this problem occurs. Ther...
Hi,I am using an STM32H753 connected to a raspberry PI via SPI. The STM32 is connected as slave. With CubeMX I configured the STM32 to be an SPI Slave with both DMAs configured as circular. I am having a struct with live data (refreshed every 10ms) a...
actually I'm using stm32F446RE, I'm using hal library just to detect external interrupt from PA1 pin but it doesn't work, and if I put the interrupt from PA0 pin, it works fine?/* USER CODE BEGIN 0 */ void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin){ c...
