STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hey guys, I've been playing around with STM32F334R8 Nucleo board's USART module. As a part of it, I have written a small bare-metal code to print a character and unfortunately, my code isn't working. I am seeing junk on my putty window sometimes and ...
Posted on June 17, 2018 at 12:09I'm reading data from a UART with DMA and want to write that data to an SD card (on a F722). Since the data is much longer than my buffer, I chose circular buffer for the DMA.The problem now is that I need to save the...
Hi all,my SDRAM setup seems to work EXCEPT that I have a strange behavior:When I write any value (8, 16, 32 bit) to an address (example 0xd000004),it in fact gets written to the address - 2, in this example 0xd0000002.All written bytes are readably @...
Hi, I want to set 3 channels of adc and transfer data via dma to buffer.But I want to read randomly, sometimes only ch1, sometimes only ch3 etc. One channel at time. And fill buffer with data from one channel.Do I have to set:-adc continous - dis...
Hello i am working on stm32h743 , and in it ADC DMA stop working but when i try to start again i does't.what is the problem in it?
