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. ...
Hi everyone!I am building a portable device wich has a batery, obviusly, and the MCU is the STM32F042. I need to use an USB to program it and charge the batery. Anyone can provide me with any schematic that I can use for the USB conections?Thank you.
I'm having problems getting my software to work with FDCAN2 on the STM32G474e-EVAL board. It works with FDCAN1, but w/ FDCAN2, messages accumulate in the Tx buffer until I get buffer fill errors.I built the FDCAN_Com_IT example from the latest STM32G...
Hi @all,we have an application, where we use the LSE. In due to weaknesses of the part we use, the LSE can fail sometimes.If I then use the __HAL_RCC_BACKUPRESET_FORCE() and __HAL_RCC_BACKUPRESET_RELEASE() to reset the LSE and LSI system, also the SR...
