I have adhered to the an5200-getting-started-with-stm32h7-series-sdmmc-host-controller-stmicroelectronics.pdf document and have had a good deal of success implementing CMD53 and CMD52 comms with a slave device but there seems to be a problemThe slave...
Hello,I have a program that works in DMA but I would like to put a function to know when the transfer in the DMA is finished so that I can recover the data continuously. Do you have any information on this ? Here is part of my code HAL_SAI_Register...
I am trying to send data from a buffer to a GSM module. The buffer contains the AT commands. For each communication this will vary. If i use the Circular mode the transfer will not end. But when i am trying to use the Normal mode so that i can contro...
My target:I want to use the same uart lines(RX line and TX line) to achieve communication between computers and multiple devices (in other words: multiple slave devices, computer as master). I use some STM32F072C8 as slave devices, and configure thes...
Hi ST community,I'm developing an LPBAM use case using the B-U585AI-IOT02A dev board and it will be deployed in an IoT device empowered by an STM32U585 MCU.My application is:1. set up LPBAM such that: RTC wakeup will trigger an I2C3 master transmit a...
Here is the setup (Using timer 1 - 16 Mhz clock, counter = 3200) using OC channel to produce scope signal on output pin):void MX_TIM1_Init(void) { /* USER CODE BEGIN TIM1_Init 0 */ /* USER CODE END TIM1_Init 0 */ TIM_ClockConfigTypeDef sC...
Good evening to everyone,I'm trying to sample various signals, both low frequency and high frequency. For the low frequency, I'm using a timer, while for the high frequency, I'm using DMA. I would like to perform read scans with the ADC, selecting th...
Hi, Iam using a STM32G473 controller and want to do the following:I want to output an analog curve, stored in a RAM buffer.Timer6 is the timebase for transfering the the data from RAM buffer to DAC via DMA.So I selected the DAC as trigger source for ...
HiI have implemented ADC1 on a DMA and verified its operation. I then implemented the ethernet stack and verified that it can be pinged. The issue I'm having is that the ADC DMA stops working once the ethernet stack is implemented. I believe the erro...
Hi. I am developing a device for working with real-time industrial interfaces based on RS485. I expect to get a delay of no more than 11 tbits (standart UART frame) + parsing execution time (few microseconds). I am using UART with IDLE IT and master ...
