Hello,I am using ADC1 channel 1, 3 and 5. All these three inputs are connected to different sensors and I want to create a driver to read those sensors. The problem is that I don't want to read all input channels at once, I want to be able to select ...
stm32g474ve , dma can be triggered using external interrupts, but dma cannot be triggered using software. In theory, both external interrupts and software interrupts should trigger events. At the same time, I have verified that stm32h750 is OK. So ...
I'm working on a project using the STM32H563RIT6 microcontroller where I need to receive data over UART using DMA with idle line detection. The data is sent from a Python script using 'pyserial'. My setup is as follows: typedef enum{ IDLE, SE...
Hello,I have tried to set up USART1 Receive in DMA mode and with FreeRTOS. RX is GPDMA channel 0, Circular mode, Destination increment address on, burst size 16 bytes, priority Medium. Source increment off, burst 1 byte.USART1 : 115200 baudrate, 8 bi...
Hello Experts ,I am generating a two-Channel PWM with complementary channels also HAL_TIM_PWM_Start_DMA(&htim1, TIM_CHANNEL_1, (uint32_t *)sin_table, 20);//low HAL_TIMEx_PWMN_Start_IT(&htim1, TIM_CHANNEL_1); HAL_TIM_PWM_Start_DMA(&htim1, TIM_CHANNE...
I am using STM32F103C8T6, timer 1 ch 1 to generate complementary PWMwith variable duty cycle Using DMA buffer HAL_TIM_Base_Start(&htim1); HAL_TIM_PWM_Start_DMA(&htim1, TIM_CHANNEL_1, (uint32_t *) base, 30); HAL_TIMEx_PWMN_Start(&htim1, TIM_CHANN...
I am transfering data array from an array to PWM register of TIM1.int16_t sin_table[20]= { 0, 39, 77, 113, 147, 177, 202, 223, 238,247, 250, 247, 238, 223, 202, 177, 147, 113, 77, 39};HAL_TIM_PWM_Start_DMA(&htim1, TIM_CHANNEL_1, (uint32_t *)sin_table...
My program collects data using DMA in circular buffer. I have following procedure to "start" collecting data. // "reenable" measurment (enable results readout) void restart_measurment(void){ run=1; // DMA channel reset CLEAR_BIT(TIM1->DIER, TIM_DIER_...
Hello, I am trying to transmit 64 byte data with DMA but if I am not use at least 10ms delay the data is not transmitted. How can I check the is data transmitted without any need of delay ? I try to check UART is busy or not fort that but its not wor...
I'm trying to use circular DMA with a SPI bus peripheral, where the DMA transfer complete interrupt causes something to happen after each block of data is DMA'd to the SPI bus. If my DMA transfer size is greater than 5, everything works well accordin...
