Hi, I have a question about using a STM32l4+ Discovery Kit ( STM32l4S5 / b-l475e-iot01a ). I’m trying to use both microphones with the DFSDM function with DMA and send it to a PC COM-Port using UART (USART1). To program the Microcontroller I’m using ...
We have a new design using the STM32G474 and are having some weird issues with the SWV utility. Current setup:STM32Cube IDEST-Link V2-ISOL Debugger using SWCLK, SWDIO, and SWOSWD connection to micro with 33 ohm termination resistorsSWO was wired manu...
I use Modbus RTU 8N1 with 9600 bd. I always have sent the same 8 byte request. The first byte of the message is 0x01.In about 85% of all tests the STM32 evaluates the request correctly. In a 15% of all tests the first byte is evaluated as 0x80 or 0x...
I followed https://community.st.com/s/article/configuring-dsp-libraries-on-stm32cubeide to install.The linker is saying cannot find -larm_cortexM4lf_math.Hears is the project settings I followed https://community.st.com/s/article/configuring-dsp-libr...
Hello.Find the attached circuit diagram for my IR sensor. The trigger is built in such a way that when it's off the IR transmitter is off and we get the sunlight values and when it's on we get sunlight + IR value and when we subtract the two we get t...
I'm using STM32G491 and I've a SuperCap mounted on VBAT Pin and using LSE with 32.768 KHz. Everything works at it should but after removing voltage supply so that VDD drops to 0V, and discharge the SuperCap to 0.6V for about 15Seconds. After this I A...
We use STM32L496QGI6 with a 512Mb external flash connected to a QuadSPI interface.Principally like the Discovery kit STM32L496G-DISCO (with STM32L496AG MCU and 64Mb flash).We wonder how the STM32 required data hold time during read from flash can be ...
Hello. I used to use the following code for starting a timer interrupt and used to set up the pre scalar and counter such a way I get the desired frequency but now this code is not working. My LED doesn't blink at all. I just wanted to check if the c...
HiI try to run SPI 1 on STM32F103C8 but when i send data i have only SCK signal. MOSI(PB5) is in high state (dont change). SPI2 on PORTA works grate.void MX_SPI1_Init(void) { /* USER CODE BEGIN SPI1_Init 0 */ /* USER CODE END SPI1_Init 0 */ ...
I have defined the enum in lets say x.h file so i can use it in x.c file , but need to use the same enum in y.c so included x.h in y.h and tried to extern it in the same file was give out error, but was working when i extern the same in y.c file. w...
