Question about SPI communication intervalWe are using HAL_SPI_TransmitReceive to achieve SPI communication, but there is an interval of some us after the SCLK outputs for 8 bits. Is it possible to change this interval time?
Hello folks! One of my devices happened to have a some kind of flash corruption, enough that an ECC NMI was triggered. Removing the "while(1)" from the default handler, to simply return from that handler to my program, did not work. I was thinking th...
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...
