SPI CLK frequency dividing methodIn microcontroller (STM32H43), SPI1, 2, and 3 use a common CLK Source.Is it possible to separate these CLK Sources?Also, I would like to divide SPI2 and 3 more than 256 divisions, but is that possible?Please help me.
hello everyoneI'm having problem with debugging stm32f103 blue pill with Keil 5.39 ans st-link v2 programmer.my programmer work fine when i load code without debug on micro but when i want to go to debug mode, my code run till the line__HAL_AFIO_REMA...
Hi,I’m using the STM32L76G evaluation board and would like to work with the CAN protocol. I have a DB9 connector but no slave devices. Could you suggest how I can test and work with CAN in this setup?
Dear Community, I started investigating issues on one old project that based on STML071xB and has been implemented by another engineer. I got confused with implementation of battery measurements. Here is the thing: 1. MCU is directly supplied by a ba...
Question about SPI communication intervalWe are using HAL_SPI_TransmitReceive to achieve SPI communication, but there is an interval of some us after the SCLK outputs for 8 bits. Is it possible to change this interval time?
Hello folks! One of my devices happened to have a some kind of flash corruption, enough that an ECC NMI was triggered. Removing the "while(1)" from the default handler, to simply return from that handler to my program, did not work. I was thinking th...
For the STM32G474QE i read that the VREF is either 2.048V 2.5V or 2.9V.is this the maximum voltage the ADC can read in single ended and in differential mode? so if i have a signal that is max 2.9V and min 0V. Will this work? or is the VREF the middle...
Hi,I tried booting the STM32F103C8T6 via UART following the boot configuration details from the AN2606 document provided by ST. I have outlined the configuration below.After setting up the boot configuration, I attempted to connect the STM32's UART u...
Hi.I have a project that involves using an STM32U535 to control the LEDs shown in the picture.I feel it should be possible to control the COL-x signals with synchronized timers that also trigger DMA transfers to control the ROW-y signals, but I can't...
I've been trying to figure this out for a while, but now my project has come along where it is incredibly inconvenient to test with the cable still inside. I've tried powering with an external supply of 5V to Vin then moving JP2 to EXT, but it doesn'...
