Hello. I am writing an SPI driver for STM32F407 Microcontroller to control the resistance of the MCP410 chip.The datasheet for the chip can be found here:https://ww1.microchip.com/downloads/en/DeviceDoc/11195c.pdf The I use a cheap logic analyzer tog...
External 32.786KHz crystal is connected to the terminals PC14, PC15 and 6.8pF, NPO Capacitors connected between crystal and GND.Battery Back-up is provided.Configured using the STM32CubeIDE (STM32CubeMX) -> Clock Configuration to use LSE (32.786KHz)A...
Hello,I use the STM32F767 microprocessor on my PCB design. After sending back the converted data to a PC with UART, I got strange characters (in Picture1). Normally, I am supposed to get the numbers like in Picture2. The characters look like Chinese ...
I am using the stm32h745-Discovery board.I am getting the data using the interrupt method and polling method but am not able to get the Data using the uart_receive_DMA. …What are the further configurations needed for the DMA and What else to do get ...
Hello,I have a timer TIM2 interrupting every 2ms (that's working).When I receive SPI data from SPI3_IRQHandler, I want to launch the interrupt of this timer TIM2_IRQHandler as soon as possible (eg in the next 10us).Then, the timer will continue to in...
MIFEN explanation would use some rewording, too...JW
Hello,It's not clear for me what a peripheral reset (registers RCC_xxxRSTR) is doing. I didn't find the details in the reference manual. I assume it resets the internal state machine of the periph, its FIFOs, but for example does it also reset its co...
I'm trying to program the option bytes on an STM32G0B1 but it keeps timing out at the end of the program sequence and never actually succeeds, no matter how many times I try.I enable the Flash peripheralI (successfully) unlock the flashI (successfull...
