Hi, I am trying to simply output information from an I2C device (DS1307 real time clock) to an SPI screen (ST7789) I have tested the code & libraries for the separate devices and they work but as soon as I try adding any SPI commands to the main.c th...
I am using stm32u575zit6q. I set Baud Rate 2500000bit/s.(my equipment is only support 2500000bits)usart write is work successful, but read is not.usart read work only 9600bit/s.How do I use the read to work over 9600baud rate?
Steps to read the temperature calibration values from the stm32l152rc
Dear All,I have the STM32G431C8U6 UFQFPN48 chip mounted on the breakout board (QFPN48 to DIP48). How to use STM32CubeProgrammer and the STLINK-V3SET to program the STM32G431C8U6 UFQFPN48 chip on the breakout board? Thank you.
I'm using SPI on STM32F407VGT6 This is the code I use to check the state of the SPI_SR_RXNE bit:This is the code for the LIS3DSH accelerometer, when I send data to the accelerometer in response the accelerometer sends data to the Microcontroller.This...
Posted on February 24, 2016 at 06:02 I am working on a project. One of the part is exchanging data between PC and MCU(STM32F4) via the USB CDC. Sending data from STM32 to PC is very easy, but there is difficulty receiving data from PC. ...
In `STM32F030CCTx` I need to set the CRC in 16-bit length by calling HAL_CRCEx_Polynomial_Set(MATRIX_UART_settings->crc, CRC_POLY, CRC_POLYLENGTH_16B); but the compiler shows the error : 'CRC_POLYLENGTH_16B' undeclared (first use in this function) in...
I'm trying to use the internal op-amps of an STM32L471 to amplify a small current-sense voltage before measuring it via ADC. This figure from the relevant product training resource shows an internal arrow labelled "ADC," coming from the op-amp output...
I created a custom board with the STM32 (F103C8T6), and I am trying to program it using a FTDI USB to Serial module. However, nothing is happening, it doesn't seem to be sending anything and when I try using STM32CubeProgrammer it says:Timeout error ...
Hello, I would like to know how to retrieve the acquisition values : INPUT -> ADC -> SAI -> µP like the diagram below : I have a program that works for this : DMA -> SAI -> DAC But this is not the way I would have wanted to make my CODEC work. Do ...
