When I use STM32G474 for SPI communication and configure it to host、 Received only mode, and use hal_spi_receive_dma() to start communication，the number of clocks is always one byte more than I want.For example，if i want to receive 3byte data and con...
Dears, I have issues with setting RTC shift register.I have setup RTC with AsynchPrediv = 127 & SynchPrediv = 255 and is working normally.I tried to periodically setting RTC->SHIFTR with value 100 each 5 secs. Then wait for the shift operation to com...
Hi, I am interfacing an ENDAT Encoder with Stm32 microcontroller, Actually my board is controlling motor as well with timer interupts . So I need to ask My code is a function having for and while loops in main().When Motor control side Interupts occu...
Hi,Anyone can help with resources (videos, Documents), to understand how to calculate time delay and execution time for CAN messages and SPI communication. I am working on STM32H7 MCUs and need to get a close estimation about the time delays, for exa...
Hello, I have a CAN 2.0 network (classic can) running at 500 kb/s. I have multiple STM32F4 nodes running the stm32 HAL CAN driver with no issues. I have another node running a STM32G4 with a FDCAN driver set to classic mode. When the G4 node is co...
Hi everyone,I am trying to power my NUCLEO-H563ZI with an external power supply. I have tried everything in the documentation (jumper positions and pin connections) including a 3.3v input (3.3), a 5v input (E5V), and a 9v input (VIN). None of this wo...
Hi, I`m new to MIPI DSI, and still learn how to use it.Recently, I develop with my custom board and start with MIPI interface display. Then config with CUBEMX, but after compile program, it always stuck in HAL_DSI_Iinit while loop below /* Ge...
I am unable to get the I2C line on my STM32H750VB to connect with my PCA9685 PWM driver on my custom PCB. The I2C line is constantly high, which I have seen on multiple oscilloscopes. I got the software online from a tutorial on the PWM driver and wa...
how can i connect the module wifi esp8266 nodemcu v3 with stm32l476rg?
I have tested the POC (Proof of Concept) by using 'Nucleo-439ZI' evaluation Board. I am now going to use the same schematics as reference for my prototype and create a custom board by removing the Morpho and Zio connectors as well as the unintended f...
