I'm trying to read the built-in temperature sensor on the MCU we're using (STM32L011F4P6)We only have the one calibration datapoint, so I can't use the temperature conversion function I'm familiar with.The code is as follows:int32_t analog_get_temper...
Hello, I have two custom boards based on the STM32G0B1CBU. When I try to program them via the SWD interface (using ST-LINK or SEGGER J-Link), I get the "No Device Found on Target" error. I checked the schematics and used an oscilloscope to make sure ...
STM32H743i-EVAL w/BSP V1.11.0SD Cards: 16GB SanDisk MicroSDHC I C4 (circle C with number inside) 16GB SanDisk MicroSDHC C2Both cards are supposed to be V2.0. Both work in all the SD devices (cameras, PC, thumb drive adaptors, USB readers). ...
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...

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...
