For the STM32G474QE i read that the VREF is either 2.048V 2.5V or 2.9V.is this the maximum voltage the ADC can read in single ended and in differential mode? so if i have a signal that is max 2.9V and min 0V. Will this work? or is the VREF the middle...
Hi,I tried booting the STM32F103C8T6 via UART following the boot configuration details from the AN2606 document provided by ST. I have outlined the configuration below.After setting up the boot configuration, I attempted to connect the STM32's UART u...
Dear all ! I in my project have 1 led was blink to know CPU still working, display TFT LCD ST7735. At the first time, led blinking as timer 3 interrupt, LCD can display all information. after i add ADC with DMA continuous mode, CPU hang, led didn't b...
Hi.I have a project that involves using an STM32U535 to control the LEDs shown in the picture.I feel it should be possible to control the COL-x signals with synchronized timers that also trigger DMA transfers to control the ROW-y signals, but I can't...
I've been trying to figure this out for a while, but now my project has come along where it is incredibly inconvenient to test with the cable still inside. I've tried powering with an external supply of 5V to Vin then moving JP2 to EXT, but it doesn'...
I am trying to receive CAN FD and save the data to the SD card, but I am having a problem . Create and deliver an event structure in HAL_FDCAN_RXFifo0Callback, Receive the structure from the application area and call HAL_FDCAN_GetRxmessage. In this c...
Hi,I am working on two STM32 microcontrollers communicating over UART with baud rate 9600. The functional requirement states that I need to transmit and receive data at both microcontrollers. Currently this is not happening as the transmit and receiv...
I measure 9 channels (3 per ADC) with 12-bit resolution using DMA. The sampling time is set to 6.5 cycles, but the same issue occurred at 2.5 cycles. I get no results at all in the range from 2037 (7F5) to 2047 (7FF), but significantly more resul...
I am supposed to be receiving 8-bit data with even parity. The blocks are defined with a header of 'F0', this is S.Bus data if anyone knows that that is. I setup a simple program that just does receive data. I get data but nowhere does it show an ...
Hi, I am trying to stream ADC data to ethernet RJ45 port along with synchronized timestamps. Currently I am trying to figure out the following problems: 1. How can we synchronize ADC data with timestamps? The STM32 tutorial uses DMA, which I assume d...
