Hi. I'm trying to read data from w25q64. When i erase and write the chip and then read it, i receive true data.But when i only read data, my chip is blank and i receive 0xFF.Is my chip still blank or i wrote the chip correctly?Why don't i receive tru...
Hi, I'm using a Nucleo-F446RE Board and I'm trying to set up a basic DAC with DMA configuration without HAL-libaries.The configuration without DMA works just fine, I can measure correct voltages with my oscilloscope on PA4 as intended. My following D...
I think it doesn't have an impact and you just get extra pins (e.g. extra SPI controllers becoming accessible) if going say 100 to 176. But it's not clear...IOW, will existing code run exactly as before? Isn't the silicon identical and they merely bo...
I am using COMP2 and COMP6 to compare external voltages to internal DAC values. I need to calibrate the internal DAC values by taking ADC measurements from the input pins. Can the ADC measurements be taken with the COMPx peripheral active? If so, h...
Hi. I'm trying to read data from W25Q64 flash memory.These are my connections:And these are my SPI and RCC and GPIO settings:And these are my functions and main code:Using W25Q_ReadID function, i could read device ID.But i can't read data stored on d...
Hi everyone,This is a follow-up to my previous question about LED behavior on the STM32H755ZI-Q when using OpenAMP communication between CM4 and CM7.https://community.st.com/t5/stm32-mcus-boards-and-hardware/nucleo-h755-led3-not-turning-on-pb14-in-ip...
Hello ST experts,I have a weird experience with UART communication between two STM32G4 microcontrollers. MCU1 sends 10 bytes to MCU2 via UART. Both UARTS are configured with 9600 Baud rate with DMA in circular mode. The Problem arises when the MCU1 i...
Hello,I am using the VENC_RTSP_Server example located in:STM32Cube\Repository\STM32Cube_FW_N6_V1.2.0\Projects\STM32N6570-DK\Applications\VENCThis example shows how to use the VENC block and stream H.264 video through RTP/RTSP using Ethernet.I want to...
Hi, everyoneI recently encountered a strange phenomenon. I opened three DMA channels on the STM32G474RBT6.The first one is Channel 1 of DMA1 (circular mode), which is used for automatically collecting the data converted by ADC.The second one is chann...
In my embedded software project, I need to write a bootloader. I wrote an application code for the bootloader and testing, and everything is fine so far, but the delay function in the application code is not working. I think the reason for this is th...
