I'm generating external interrupts on an WeActStudio STM32F446RET6 board. I've the pins configured as pull-up. When I set one of them to GND, several random interrupts from other pins are generated. For example, if I connect pin PB3 to GND, I get int...
Hi, I have a strange situation I can't figure out. I'm new at DMA so I just follow directions as best I can without a full understanding. Right now, my setup is more or less working for a few months. But today I encountered a problem. I am using UCP...
Dear Sir,We are using the STM32H747 series microcontroller in one of our custom projects.Could you please recommend a low-cost on-board debugger suitable for this board? Ideally, the debugger should also be compact in size.Your assistance on this mat...
I am using the NUCLEO-U575ZI-Q.I am using the OSPI peripheral in QSPI mode.The device I am communicating with needs a longer delay after the CS line is asserted low.I have tried setting the "ChipSelectHighTime" to 8, but I think this only affects the...
How to download datasheet stm32f103c8t6? Why is it unavailable?
Hi Team,We are using the STM32H753VIH6 in our design.We are connecting the Realtek RTL8364 through RMII interface.I have powered the STM with 3V3.Attached the waveforms for undershoot and overshoot accepted levels.This has been probed with 2GHz Oscil...
Hey, I have a STM32H743IIT Board with an QSPI W25Q128J Flash, i use LTDC and LVGL.I want to store my pictures in the Flash Memory, but i have some Problems with the External Loader or the Mapping, or something.The Flash workes fine, when i Write a bu...
Hello!Using TIM1 for pwm input capture.Works OK for trigger prescaler 1 (default).Want to use prescaler 4, but it doesn't work. Capture value the same as prescaler 1. Timer config:void FC_SERVO_1_TIM1_Init(void) { // USER CODE END TIM1_MspInit GPI...
Hy, i am new here and need help. Is there an exemple of a cube ide project with all the important files like .ioc ect.?I have problems with the onboard display.I use the sdram bank2 as framebuffer (startaddress 0xd0000000). I can see (mem window) th...
Hi there,I'm currently trying to get SPI Communication with the LTC1403 up and running, however I'm struggling with the timing of the Conv Signal.It seems like I need the rising edge of SCK at the same time as the Conv Signal is high. How can I achie...
