Good afternoon, I have some questions for reading multiple channels of the ADC in continuous mode and map the results in the DMA. I have been able to monitor the voltage coming from a potentiometer and map it into the DMA and i can see the values in...
Hello everyone New STM32 user here, more specifically STM32 U545 RE-Q. I am kind of new and i would like to start acquiring some data with the STM32 ADC, triggered by a timer, and send the data to the DMA so that i can use the CPU for other stuff. D...
As mentioned in the topic subject, I would like to implement I2C Slave device which will simulate the BQ769x2 device. For development I'm using STM32F4 Discovery board, but the final product will be deployed on STM32L0.Master device is first trying t...
Hello,there seems to be a problem in function SD_read with reading data in DMA transfer mode to cached buffers.I've enabled cache handling with#define ENABLE_SD_DMA_CACHE_MAINTENANCE 1but there is a serious problem with calling SCB_InvalidateDCache_b...
Hi I am using a STML4xx processor and use HAL for system initialising, and sending strings through the USB port. It works most of the time. I call the below function SendString(...) to send string through the USB port , never within an interupt. I ...
Hi, I am using an STM32G0B1CBT and using the example shown in the following video to implement a USB-C PD sink with TRACER_EMB and UI_INTERFACE utilities for debugging. https://www.youtube.com/watch?v=-vsJhNIaHxEAfter compiling and running the code, ...
Hello,Trying to read STMU575 Internal Temperature Sensor, we get wrong readout.We need you advise on what is required to get correct temperature readouts from the STM32U575 temperature sensor.A. We use ADC4 configured as follows:B. The below detailed...
Hello,I am reaching out to ask if it would be possible to get some help configuring my esp01.c library.I am currently developing a library that utilizes DMA, interrupts, and a circular buffer to communicate with an ESP-01 module. The module is connec...
Hey ST,In the FW package that comes with the STM32H7S78-DK, I've been using the Template-XIP project as the base for my own project, and I noticed this issue with the MPU setup of the external SDRAM on the XSPI1 line. Whenver I would try and access m...
Hello everyone,I'm currently working on a USB Type‑C Power Delivery design using the STM32U575VGT6Q and the TCPP01‑M12. According to the TCPP01‑M12 datasheet and the example from the UM2581 STM32L5 Nucleo Board, the DB pin should be connected to a GP...
