WebDec 22, 2024 · HAL_StatusTypeDef HAL_DMA_Start (DMA_HandleTypeDef *hdma, uint32_t SrcAddress, uint32_t DstAddress, uint32_t DataLength) Starts the DMA … WebCurrent solution: I2C + DMA circular buffer without repeated calls of HAL_DMA_Start_IT ( RELOAD bit still need to be updated each 254 samples). This solution is based on code from HAL libraries. Idea is to start transfer the same way as in HAL_I2C_Master_Transmit_DMA function when hi2c->XferCount > MAX_NBYTE_SIZE:

WebMay 7, 2024 · I've noticed in earlier post, you said the DMA is set to half-words (16-bits) and then start this once: HAL_SPI_Receive_DMA (&hspi1, DMA_buf, sizeof (DMA_buf)) The HAL driver mislabelled the size parameter - a better name for it is transfer count. The sizeof works when the data size is byes but not for other sizes.

First of all Let’s see the clock setup. Notice that the APB2 Timer Clock is running at 80 MHz. Now we will enable the Timer 1 in the PWM output mode. Also note that the Prescalar is set to 0, and ARR is 80-1. Since the Timer 1 is connected to the APB2 clock, it was initially running at 80 MHz. Now we use prescalar of 0, that ... can cats have pig ears
