Hi all,I got a strange issue. I'd like to use USART3 or UART5 on my STM32F446 chip. We have the chip on a pcb, so I am not talking about the nucleo board. The issue is when I do the system_clock_config(), the listed uarts does not work. void init() ...
I have the strangest problem ever seen and I would not believe it has it not been this repeatable: I have a single DMA controller running 3x streams. Two are for ADC and one for DAC. All three can run simultaneously, the DAC at 1 Msps and the ADCs bo...
I'm running a STM32L073 to generate a sine wave tone via I2S in normal DMA mode. The amplifier is a MAX98357A. The MODE pin is connected to VDD so only left channel is considered. I2S runs at 48kHz and the uC clock source is internal. The output tone...
Hi all, I am using register mode SPI for communication purposes, clock is 210Mhzinterrupt is for every 4khzinitialized SPI with HAL formatSPI data rate: 35MBpswhen I send data through SPI I can find some jitter inside it. But when I drive the same si...
I am trying to transmit through SPI to a MAX7219 chip on my STM32F412G-Discovery board. The system clock is running at 100 MHz. I am using a level shifter to handle the 3.3V -> 5V voltage changing. I have used this IC on an arduino so I do know it wo...
I am using an STM32G070RB nucleo 64 board with an ESP 8266, earlier I was using DMA to establish UART communication between the ESP and STM32, but now I have switched to UART interrupt mode to receive and transmit data. When I software reset the ESP ...
Hi, I have a simple code running on STM32L0 MCUs. I will need to change some data on their firmware on each board depending on some analog properties of another component.There is a practical way to program a portion of memory with some data after th...
I want to receive hex data from terminal like 0x66, 0x55, 0x44, 0x23, 0x11, 0xaa, 0xbb, 0xcc. Normally we can receive messages in string over UART. But I want to receive hex data instead of character or string from terminal. I am using stm32cubemx HA...
Dear ST community,What is my problem?I’m having a very hard time to get the I2S communication between a STM32H745IIT and a CS4272 audio ADC/DAC running. The STM is the I2S master, the CS4272 is the slave.What I am trying in the first place, is to sen...
