HAL_SPI_TransmitReceive_DMA() can lead to non-functional DMA when the following happens:RX DMA state readyTX DMA state busyHAL_SPI_TransmitReceive_DMA() gets calledThe result is that RX DMA will become busy and never recovers due to the logic in line...
Hello everyone,I am facing an issue while trying to interface a 24-bit PCM mic with the STMH743ZI2 microcontroller using I2S2 in master receive mode with 24-bit data in a 32-bit frame(set using CubeMX). Although I have placed the I2S buffer in the ad...
Hello! I am working on PWM generation using several timers, in this case: TIM3, TIM4, TIM8, TIM15. I have gotten TIM3, TIM4 and TIM8 to work perfectly. I am currently testing this on a STM32F3DISCOVERY board. TIM15 however, does not behave properly f...
Hi fellas,I'm interested in implementing the firmware upgrade over the air (OTA) over BLE. I've came across dedicated STM's MCU family STM32WB too. But I'm more concerned about implementing in STM32L0/4 series family of MCU. Which MCU would be suitab...
Hello everyone. I'm trying to use the TIM6 as a timer at 1 kHZ. However the result I get is 500 Hz. I couldn't figure out why. I maxed the CPU clock speed at 168kHZ, which gives me the result of 84MHz APB1 Timer Clock. I calculated the auto reload va...
Hi all,I need to control 3 BLDCs on one board. I found that in order to precisely control BLDCs, you need a board with special motor control timers. I have only been able to find boards with two of these timers (Example NUCLEO-H745ZI-Q) but I need on...
The STM32L4 Discovery Kit IoT node hands-on seminar presentation is available on the ST page, but the training material is not.Is this training material available for download? The application I'm working with intersects a lot with what was taught in...
Hi everyone,I'm quite new to the STM hardware and embedded programming in general. My goal is to connect the B-U585I-IOT02A to a WPA-2 Enterprise WIFI (it needs to be that standard).I found the examples in the git repository about connecting to WIFI ...
Hello,I have an EM-36 eMMC connected on the SDIO port of my STM32H747 (it is on an Arduino Portenta H7 board). We are trying to verify that the communication works correctly with the eMMC and ultimately the objective is to mount a file system on it. ...
