Baud rate
In a spectroscopy application I am sampling the incoming values at 300kHz with a 12-bit ADC so i will be having a bit rate of 3.6Mbps do i need to have the same baud rate. I am doing it using stm32f401re

Suitble Hyperram for STM32H735
HiI'm designing a PCB using the STM32H735 based on the eval kit STM32H735G-DK.Since the HyperRAM S70KL1281 on the eval is EOL I'm looking for an alternativeI have read a few posts with issues on this subject and I'm usure which part i should go with...
Timer Update DMA with spi is working but remaining is not working
Hi there,Iam able to send data to external DAC with SPI DMA timer update on the SPI-2, the processor is not halting but we have a UI here on SPI 1 the touch was not working. This is happening after enabling the DMA of SPI-2.Please find my code where ...
Using SPI Commuication with desired rate in Nucleo-f469ZI board
I am using Nuckeo-F429ZI board for my project.I am using SPI HAL drivers for the SPI communication.I need to transmit a data stream of 12 bytes for every 10 micro seconds with clock speed pf 2 MHz.I have tried it using SPI HAL drivers, but I'm gettin...
SPI pin states during bootloader detection phase
I have questions about SPI interfaces and the boot selection. I am not using SPI for the bootloader and I don't want it selected.Issue 1: AN2606 says that to prevent SPI from being selected, SPI_MOSI should be at a known state (high or low) at the st...
UART transmission
Hi, I am implementing UART transmission using DMA. The output of the TX pin is hooked up to logic analyzer and shows that some data remains on the tx pins after the board being updated with new version of the code. The data shows even if I remove the...
Resolved! Where can I find out or download MX25L6433F_STM32G071B_NUCLEO.stdlr?
Hi All,I am using STM32G071RB-NUCLEO + X-NUCLEO-GFX01M2Questions,Do we must use external loader and which loader file name we MUST use? is the loader file - MX25L6433F_STM32G071B_NUCLEO.stdlr correct?Where can I get this loader file.Why in sample pro...
STM32H5 Dual Differential ADC changes common mode voltage depending on clock setting
Hi guys, I'm running two differential pairs into two ADC's of an STM32H562RG. The traces are DC blocked by 47nf caps. The ADC's are setup in a master and slave dual simultaneous differential mode, running at 2 MHz each. Data is transferred by DMA. Th...
