STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Many engineers I know use HT7533 as power supply for STM32F105RBT6 in automotive boards. I looked up the specs, and found that HT7533 is only rated for 100mA. Is it too low for STM32F105RBT6? Is TI's TPS7B91 or TPS7B92 better in this case? Thank you.
Hello everyone, Using the STM32H723VGT6 chip, the program can be downloaded and run normally, but cannot be erased and uploaded, prompting "Error while determining flash info (Bank 1 @ 0x90000000) Failed to read back". The same phenomenon occurs wh...
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...
Hi. I'm trying to use STM32H573IIKxQ's SPI using HAL.I've noticed that the HAL library disables the SPI after each transfer which causes the SCK pin to go high and goes low again before the next transfer, which causes an extra bit being shifted to th...
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 ...
I am trying to program STM32 blue-pill board with STM32F103C6T6A microcontroller and using STM32CUBE IDE. But nothing is able to upload the program to the microcontroller. When trying to upload the program, the following error messages are showing....
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,...
