Hello,I have a STM32L152RE and I use PA1 (Pin type is FT 5v tolerant) as ADC_IN1. Vdd is 3.3V and the voltage on PA1 usually is around 5V and sometimes it drops to 2.5V ( when I need to take the measure). Several comments on various blo...
Hi, I have a STM32G474 connected to a Quectel LTE module via a uart4 and a GPIO pin.Under normal conditions is it possible for the CPU to boot from flash and when the quectel changes the level of the gpio pin of the STm32, the CPU jump to boot from u...
Dear All, I am having difficulty with the Bootloader on an STM32469.It is on a custom PCB (which works fine in all other respects), and I can use the SWD interface via J-Link perfectly OK (with both STM32CubeIDE and STM32CubeProgrammer).My starting p...
I have created my first PCB with a STM32C011F6P6 on it, but I am not able to measure a GPIO I set high from my testpoint.I am setting PB6 high the following way:I flashed the code to the MCU via the cube ide and it told me that everything went fine.T...
The link on the bottom of page 158 is bad.There is no SBF flag in PWR_CR3, actually it is in PWR_SR1.
I have made a PCB with the STM32C011F6P6 on it and am trying to program it via an ST-LinkV2. While trying it out yesterday, it connected just fine with the cube programmer. Now I am trying to do the same thing again, but both the cube programmer and ...
The Reference Manual for STM32U0 series MCUs, RM0503 Rev2, specifies, in table 2 on page 57, that SRAM starts at 0x2000 0000 and ends at 0x2002 9FFF. This is a contiguous region with a size of 168KB. However, the Size column shows 40KB. This docum...
I downloaded the STM32H753 SVD file from https://www.st.com/resource/en/svd/stm32h7-svd.zipI have found a number of discrepancies between this file and RM0433 (reference manual)That leaves me wondering if this file is outdated and a more recent, cor...
I am trying to create a custom keyboard, and I was trying to flash my board with stm32f070c6t6 MCU in DFU mode using cube programmer, but I keep getting "no DFU detected" (of course while pulling BOOT0 pin high).Also, every time I plug my device into...
Hello,I am using the internal pull up for the input pins, but when read the port status using the program, it always reads 0 instead of 1. I expected it to read 1 and if make that pin grounded it shall read 0.
