STM32H743ZI spi communication is not working at Baud rate 80 Mbps or even greater than 40 Mbps

Hi,I have configured STM32H743ZI spi1 as master and spi2 as slave and code is generated using stm32cubemx spi is successfully working till 30 Mbps.but if configured at Baud rate of 80 Mbps or even greater than 40 Mbps slave is not able to receive d...

Problem while writing to SPI data register on Nucleo-64 , STM32F411-re

I am new to this nucleo board ( Nucleo-64 , STM32F411-re). I've configured SPI1 port as master and SPI4 port as slave. I am trying to establish communication between these two ports and verifying the data weather its reflecting on SPI1-> DR data regi...

I am trying to send 20486 bytes of data through UART at 2 Mbps. However, I am not able to send full data at this baud rate. Baudrate of 115200 works fine for sending this data however at 2000000 baudrate, it is sending only partial data?

Below is the code for sending data at 2 Mbps baudrate. #include "stm32f4xx.h" #include "stm32f4xx_hal.h" #include "stm32f446xx.h" #include "stm32f4xx_hal_cortex.h" #include "stm32f4xx_hal_tim.h" #include "main.h" #include <string.h> #include <stdint....

Nucleo-F103RB and Adafruit C1188 SPI doesn't work

Hi,I have small problem with connecting external sensor to my F103RB NUCLEO board. Im trying to connect Adafruit CAP1188 module through SPI normal mode. I send example messages and dont seem to get the right answer(I get 0). I just want to check if e...

H Bridge PWM/OCM access with delayed Hi Enable (e. g. for SLLIMM Boost)

The SLLIMM Modules (e. g. STGIB10CH60, see AN4768, page 46, Figure 45) need a delayed start of the High Side PWM signal to load the bootstrap capacitors.When I try to do this with STM32H7 PWM or OCM mode, unfortunately this fails, because STM32H7 has...

Working with WIFI module.

I work with WIFI module on B-L475E-IOT01A. I want to configure the module as a server and to connect to it with a client (say a phone).Looking at an exampleint wifi_server(void) { bool StopServer = false;   LOG(("\nRunning HTML Server test\n")); ...

when trying to connect with the serial port this is the message I got and the uart connection is completely lost and is there any possibility to reestablish the connection?

Connect Li-Ion battery to VBAT on STM32L4S5

Hello,In my system I'm using one Li-Ion battery and there is no possibility to add another battery to the system. So just one Li-Ion. I was planning to use the Li-Ion battery until a voltage of around 3.0V. Then I would disable the LDO which is used ...
