Hi there!Here i'm with another question about UART. I know i have a tree mode for receive data from uart 1) Polling 2) Interrupt3) DMAi know the difference , but i'm soo confiuse about :Example : I work with interrupt where i put this declaration HA...
*How to save varibales or array of data in Internal memory on STM32F042G6*Can i get some example to understand this thing more clear.Thanks in advance.
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...
