Hi, I am using STM32F407 board to communicate with a serial device. I have been using HAL_UART_Transmit() to send the data and using HAL_UART_Receive_DMA() to receive the data. Part of the code is shown below. After every receive command I am suppose...
I am currently trying to get an SD card working with SPI on an STM32L4R5ZI Nucleo board, using STM32CubeIDE V1.13.2 using the latest L4 embedded package. I currently have my code opening the card and even opening the file (I receive FR_OK for both, e...
While setting up input capture for the stm32h743 using the IOC. On timer 2 channel 4, I have pin conflicts, but the IOC gave me the option to use "input capture direct mode from remap". I can not find a description of what remap means.
We are using STM32H743IIK6 microcontroller. When using analog pins(ANA) to receive analog input signals, will their be interference effect if the two pins are next to each other?
Hello everyone. I want to understand the CORDIC engine, using the nucleo-u575zi board. The guide says that the cordic uses data in q1.31 format. Could please someone explain how to convert results into an ordinary int value? And how to convert an int...
hi guys,I hope this message finds you well.I am currently working with the STM32H743Eval2 evaluation board with an external nand flash memory "Micron MT29F2G16ABAEAWP" , and i'm trying to run the code provided in the firmware on the same memory but ...
I was looking at some slides that I found called STM32H7- CORDIC co-processor (CORDIC, Revision 1.0) and noticed the following on slide 6: According to this, the fractional number being represented by the fixed-point integer bits is (-1)^s multiplied...
I have a written C# windows application that receive data continuously from MCP2221A. MCP2221A receive data from STM32 UART through receive data line. When the laptop goes for sleep (in battery mode), it send a suspend signal (it will go low) to the ...
shall we able to configure stm32g431mb gpio to high impedence state when configured as output pin. We need to access output pin in tristate mode
Dear all,Apologies if this is a naïve post.I am trying to find a processor for the product that I am working on with larger RAM and FLASH but it must remain pin compatible to minimise code changes. The current processor is this "STM32F756ZGT6". With ...
