Hello all,Regarding the STM32H725 bulk capacitors:Question 1:Is the capacitors required values taken into consideration the capacitance degradation Vs DC bias?For example:The SMPS input required is 4.7uF (10uF recommended)Looking at the STM32H735G-DK...
I am working with an SMT32u5g9vjt6q and a genuine stlink-v3set from mouser, everything was working as expected until I #included a library...at that point when trying to upload the code via the debug button I would get an "Could not verify ST Device!...
Hi,I have been using Mem Read and Write for my project involving STM32 and ST25DV64K. These functions have been working for me previously but now they return HAL ERROR. I used to encounter this when I was inputting the wrong address but I have since ...
Hello Everybody, I would like transform the HAL_GetTick() function more than 49 days.I don't find a NVIC overflow on this function to increment a second variable. In my while I have do this with uint32_t Mem_GetTick; uint64_t Tick64; while (1) ...
Hi everyone!I have this code where the mcu goes into STOP3 mode, and is waked up by a button triggering a wake-up pin.But it only works in debug. Without the debugger, the mcu immediately exits WFI.In debug, when I execute che code, the user led turn...
I am a beginner and learning I2C DMA, could you tell me what I'm doing wrong?I connected the LCD to Blue Pill and it works fine with function "HAL_I2C_Master_Transmit" i.e. without DMA!But, when DMA is configured, it is dosn't works!Very simple code,...
Does anyone know if the STM32H7 series supports the capacitive touch sensing library?We're using the STM32H743 in particular
Hi, I am a beginner user of the stm32 board. I am working with an ICM20607 IMU sensor, and I want to read the accelerometer data (x, y, z axes) using the Cube IDE. I ve read a lot of sources for one week but couldn't find a way to fix it. I can't see...
Hi,uc: stm32f446 I have a question regarding non standard word length over RS485.I need to receive next frame over RS4851 start bit, 16-bit data word, 2 stop bits, in total 19 bits.UART implementation allows to receive 8 or 9-bit data words.Could you...
Hello ST Community,I am seeking guidance on how to properly configure the VDD50USB and VDD33USB pins on our STM32 device when we are not utilizing the USB functionality. The explanations provided in the datasheet and application notes are somewhat am...
