STM32F0 with ADC and DMA with Renode

I'm trying to run an application on Renode that uses ADC and DMA for the STM32F030F4P, I created a stm32f0.repl file with the dma and adc as follows: dma: DMA.STM32LDMA @ sysbus 0x40020000 [0] -&g...

As it's optional, you can remove it completely. This would lead to DMA not being used. It seems that what you have written should be doable, and it's a bug that it's not possible. The STM32LDMA should...

Receive UART messages in DMA

I am trying to receive messages in DMA mode, on a STM32L432KCU. The pins PA2 and PA3 are configured as DMA pins. The baudrate is 115200 and the global interrupt for USART2 is turned on. In the main fu...

Try changing the order of the initialization procedures. MX_GPIO_Init(); MX_DMA_Init(); MX_USART2_UART_Init(); The DMA needs to be initialised prior to using the UART.

STM32F7 Two Timer Channels Share One DMA Channel

I am trying to write a driver that sends DShot commands to an ESC. I am using an STM32F722 MCU. The DShot protocol is similar to addressable LEDs where 1/3 duty cycle represents a 0 and a 2/3 duty cyc...

I decided to instead use TIM5 because it shares the exact same pins as TIM2. However, TIM5 has no overlaps on the DMA Request Mapping. After changing the code, it works just as intended.

DMA transfer form kernel to user space

I am trying to realize DMA in Xilinx, using DMA Engine. FPGA guys give me an AXI DMA IP-Core with DMA support, so I need to write a driver, which will transfer data from kernel to user space buffer. H...

You probably want to implement mmap method of struct file_operations. Consider: static int sample_drv_mem_mmap(struct file *filep, struct vm_area_struct *vma) { /* * Set your "dev" ...
