Using DMA for USART Rx to get an interrupt whenever a byte of data is received

Hi,I have an application that is running many tasks with different priorities. So whenever the user enters data, the task containing uart_read function might not have executed. So currently I am using RXFNE interrupt which gives me an interrupt on th...

What MCUs would be appropriate for a low power, high UART count, external RAM and ROM application

We need to replace an end of life ARM 9 based SOM and I could use some advice on what ST Micro MCU would be a good replacement. The requirements that seem to be driving the choice are low power, 9 or more UART/USARTs, 2 or more I2C, at least 8 Mbytes...

Where is the CompleteCallbacks are located in layered architecture?

I am using STM32F405xx and Cube IDE environment to evaluate my app. A layered CAN communication is requested. At this point, there are three layer to build this architecture. 1. 1.Layer is HAL library for CAN provided by ST and CubeMx: can.c and can....

Why is STM32F303RET6 not available ?

We created a design with a STM303RET6 (lqfp64) microcontroller. For the first prototype pcb's we need 5 of this type microcontroller. But the problem is that no one can deliver this item (e.g. Farnell, Mouser etc). They don't give any explanation why...

Received a mail that I have lost my seat because I didn't purchase board. I did, for an earlier workshop, then I moved the date to the 25th.

TIM1 appears to be incrementing at a strange rate when generating a pulse

I am working with the STM32F769 microcontroller and I want to generate a pulse on PE14 that is "a few" milliseconds wide. My SystemCoreClock is 216 MHz and my timer, TIM1, is hooked up to the APB2-bus, which is clocked at 108 MHz. My code looks like ...

I already have a STM32H735G-DK board for the workshop on 25th March.

I already have a STM32H735G-DK board for the workshop on 25th March and therefore do not need to order it.Today I have received email with the following ():"..we have allocated your seat to another participant."but I already have development kit.

Setting up ADC in scan mode - callbacks not working

Hi,I'm having some hard time setting up my STM32F303RE Nucleo board for using the ADC.What I want to achieve is...scanning 10 sensors (each connected to a GPIO pin on ADC2) in sequence three timestransferring the data using DMA to a buffergetting cal...
