Hi everyone ! I am having problem with the I²C connection. The problem is that, normally the the SDA and SCL pins work properly (I checked it with a logic analyzer) but when I connect them to the module or sensor I use, both of them goes LOW and stay...
We are planning to use STM32H753X in one of our design. For JTAG interface I can see two options 5 pin and 4 pin JTAG. Is STM32H753 supports 4 pin JTAG? If yes, how to manage NJTRST pin? Shall i connected NJTRST pin to NJRST? what is the use of 5 pi...
STM32 NUCLEO 64 -F411RE From SMT32Cube IDE I build & upload the following code that does nothing ,stripped everything away to show that the ST-Link is working,#include "stm32f4xx.h" int main() { while(1) { /* Do nothing */ } } This b...
i have STM32103RBT6, i want to use all three UARTs for a project. i want to use UART2 thorugh PA2 and PA3. The connection are : SB61, SB62 and SB63 are open. SB13 & SB14 are open as well. Continuity is there between SB62 & SB62 to TX on ST link (from...
Two STM32H743 series MCUs are on a single board and they communicate using SPI. When SPI clock frequency is more than 1.5 Mhz, SPI communication is not working properly. The distorted clock signal waveforms at high frequencies are attached below.A 51...
Hello everyone,I have designed a custom board using the STM32F407VGT6, and I have connected a 3V coin cell battery (CR2032) to the V_BAT pin as shown in the schematic below:V_BAT Circuit Details:A 3V battery is directly connected to the V_BAT pin.A 0...
Hi sir, I am Sridhar from Sirveen stm32f746g-discovery board Datasheet is not given Operating temperature details. So please provide clarification or provide link for download including temperature readings datasheet please.
Hello.. anyone can advise where to find user manual and schematic for Discovery kit for STM32H750? I would like to know if H750 Disco is using Ethernet MII or RMII? I was looking at F750 Disco is using RMII. TQ!
Hi I am trying to send data from the ISM330DHCX sensor to BLE (BlueNRG-M2SA) on the STM32F401 Nucleo board. I have installed the XCUBES_MEMS1 software and successfully tested the LED example via BLE. Now, I want to transmit the ISM330DHCX sensor data...
Hi community,Where can I buy the STM32F407-DISC1 and Nucleo-F446RE boards in Morocco? Can anyone guide me on this?
