STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hi, I am trying to read data from a sensor over I2C, I am using pin B8 as the SCL line and B9 as the SDA line. The code worked once and after reading the data from the sensor, pin B9 got stuck pulled low. I terminated and reloaded the debug session a...
A few days ago I successfully tested erasing the NORFlash as entire chip erase, block erase, and sector erase. I also was able to write a string to Flash and read the string back out of Flash into a buffer. After working on other development I came ...
I am using a NUCLEO64-G474RE as an SPI master with DMA (Rx and Tx in circular mode) to interface an ADC CHIP. I am receiving data reliably but wish to stop and start the SPI/DMA . I have used CubeMx to generate the initilisation code and HAL_SPI_Tra...
Dear all,First of all, I would like to say that my experience con STM32 uprocessors and STMcubeIDE is limited.I have defined a FMC on STM32CubeMX as shown in picture 1.Then I have defined a function to test FMC. The function is: Test_DPM, shown in pi...
Hi, I work with low power sleep mode in stm32 and it is sleep mode works well in our programme.MCU goes sleep mode after 5 seconds and wakup for external interrupt pin to connect for MCU wake up.But I need a output for MCU sleep for 1 min without ADC...
Here i am trying to generate a 24 bit PWM signal using timer 2 in STM32F401RE controller. I followed as per the steps only but still i not getting any output waveform on my logic analyzer. Please share your suggestions. void tim_init();GPIO_HANDLE pw...
Lately, I have been trying to program the UART module of the STM32F746ZG. The program didn't work at all. I tried programming the USART module as a UART. The program worked. I then noticed that the reference manual does not talk much or barely anythi...
Hello,In a chip like STM32U585CIU6Q, where the VDDUSB is internally connected to the VDD, what is the behavior of the USB circuitry if the VDD is below 3.3V (e.g., at 2V)? Will the USB just stop working without affecting other non-USB functions, or i...
I tried to port some code from an STM32F4 development board to an STM32H743 NUCLEO development board. I noticed that the code for the USB Mass Storage Device Class was no longer working. After spending hours of troubleshooting I found out that the "B...
Hi - I have a new board with very minimal parts other than a STM32L451VET6 micro and a SPI LCD.I have implemented SPI and the micro is sending data when I single step the program. When I just let it run it Sends exactly three and one half bytes... ev...
