I'm currently troubleshooting a STM32H750 QSPI implementation, and wanted to check that the prescaler was running correctly. So, on page 892 of RM0433 it shows a feature in the QUADSPI CCR called FRCM (free running clock mode). The catch is none of t...
I am communicating Nucleo H743 with several PN532s using SPI. I edited waveshare's stm32 codes, I didn't use DMA or interrupt. I am trying to reduce the SPI speed so that the reader can work when I extend the cable length. Since I could choose the SP...
I need a to read and write a simple 16 bit user configuration value that's stored in non-volatile memory. The STM32L0xx is famously short on memory and as such bringing the entire HAL in is out of the question. It swells up the code space well beyond...
I am using 6 channels adc with 46uSec sample rate. the reading is pretty good with dma. and I use TIMER trigger adc reading and get data from dma call back function. but every time I only get one sample for each channels, it is possible to set multip...
I am trying to measure the frequency of a square wave using TIM1 in direct input capture mode (STM32F3-DISCOVERY) . I can measure the frequency successfully , but i want to add an input prescaler, no matter what the value of prescalar i set i get the...
In the STM32H7 datasheets, page 23 (H750) or 26 (H743) - ST says the device has 2KB user option bytes flash area. Does anyone have idea if this is a typo? Or how to access this memory?If it really is there - it has a good potential to be used as conf...
I am using nucle-h745ziq ,SPI1 as Full duplex master and SPI4 as Full duplex salve.And both have same freuncy 25MHZ .And spi1 prescalar is 2.But SPI4 is not start the communication.Both structure parameter are same.In spi.c libabry I am uing if(HAL_...
