Hi All,I am looking to use the I2C3 for connecting to an OLED display. I have already used I2C1, and due to design requirements, I cannot use the same bus to communicate to the OLED display, and hence I2C3 is my only option. I2C3_SDA is an alternate ...
Hi there,Looking into the TRM for the STM32L412xx board, I was wondering if I could use a DMA to copy constant data from the Flash to SRAM. The system architecture block diagram connects the DMAs to Flash through the DCode path:However, while reading...
Dear allSituation 1:I use Nucleo-F413ZH with AMC1306EVM (PA8 DFSDM_CKOUT, PB1 DFSDM1_DATIN0)Result: DFSDM is working fine with DMA. In this situation I use mode PDM/SPI input from CH0 and internal clock.See code details in files with ending dfsdm_clk...
The problem that I am facing with the CAN communication using STM32F412G-DISCO is that the CAN transmission from the STM32F412G-DISCO devboard is working fine, but the mcu is not receiving any data on the CAN bus. I am using a CAN analyser to send t...
I am new to stm32 and i want to know how to send message to pc over usb using a stm32h747, thanks!
EDIT: The program is stopping at _WFI() but the current consumption is too high (3.9mA). I'm using STM32L476 processor and while trying to enter stop mode (tried both with and without tickless mode), the program never waits at _WFI(). Is there a way ...
Hello everyone.. I mistakenly shorted the DAC1 pin on my Nucleo-F446ZE development board with -12V. As a result, when I am trying to power up this board, PWR LED LD6 is not glowing and U4 IC is getting heated up a lot. Also, LD5 over-current LED is g...
Is there an example code to configure the internal VREFBUF on the STMG474RE (Nuclo-G474RE board). to output for example 2.5V to be used by the ADCs. I do not want to use the external reference on the board.ThanksDavid
Hi, I'm using the LoraWan_EndNode and stop2_mode examples, but either way I can't get the datasheet current, 1 μA, but I managed at most to get 21 μA, and usually around 650 μA. What do I need to do to get the right current?
