Using Direct Memory Access (DMA) in STM32 projects
In many microcontroller projects you need to read and write data. It can be reading data from peripheral unit like ADC and writing values to RAM. In other case maybe you need send chunks of data using...

Use fixed integer types to enhance portability
If you have programmed anything with C you should be familiar with common data types like char, unsigned char, int, unsigned int, long int, long long int, etc. It is really hard to tell by looks of...

Multichannel ADC using DMA on STM32
Last time we have tried to do single conversion of one channel. We were waiting for result in a loop which isn’t effective way of using processor resources. It is better to trigger conversion and wait...
