I've been writing apps using the STM HAL drivers for a while. I'd like to move to the low level drivers in order to have a better understanding of what's happening in my app. Comms over a UART with DMA is a critical part of most of my apps so I'm s...
Dumb question, can the DMA perform separate, parallel operations with the different channels? For example, could I use the DMA to transmit with the UART and the SPI devices at the same time without one interrupting the other? I'm unclear from readin...
I would use a b-l072z-lrwan1 to implement a lora gateway using ping pong example and send data to PC through serial, receiving data from serial and send response to other nodes that are still b-l072z-lrwan1
Posted on May 18, 2018 at 07:29 Hello everyone, I want to run 2 rotarty encoders on my STM32F I'm using cubemx. The first one is a 2000 step rotarty encoder like these: https://www.aliexpress.com/item/1pcs-E6B2-CWZ1X-2000P-R-encoder-for-Omron...
Hi All,I have two Questions,The first one is:I was trying to use one of the SPI examples provided by ST SDK, but the "STM32L476G-EVAL" target doesn't have an SPI example, so I used the NUCLEO-L476RG SPI_FullDuplex_ComDMA example as a reference.I was ...
"Hello, while examining the STM32L412C8 microcontroller, I came across the term VDD12. What is VDD12, and can I use the peripherals without making the VDD12 connection? In other words, is it mandatory to make the VDD12 connection?"
ESP-01 is supported on fanout expansion board, how to connect WIFI and send message in local area network? Is there any example?
Hello to everyone,I would like to know more about 'one pulse mode'. I'm using a STM32F446RET and I need to generate 1 or more pulses when an event occours.In my project, channel 1 of TIM9 is the pin chosen to generate the waveforms.I got that the 'on...
I experience a strange problem with I2C, DMA and the latest STM32U575ZI-Q, not seen on L4 and H7 MCUs.After a successful data transfer from SMBus target (slave) to controller (host) the last PEC byte stays in RXDR registry. On the next transfer in th...
Hi, My requirement is when User button 2 is pressed, need to change the speed of the motor. So, I tried to set, when userbutton2 is pressed, motor should start/stop as the function already set in userbutton1. But there is no change in the working. ...
