Resolved! Why is the rated supply voltage for the 5V pin regulator on the bluepill datasheet 4.0v and not 5v?
I would like to know whether the stm32f103c8t6(Blue pill) can be supplied using a 5v source through the regulator ( 5V pin); I've seen a lot of people indicate that it was possible but the datasheet clearly says that the maximum voltage the regulator...
Resolved! Cannot connect to Blue Pill using STM32CubeProgrammer with ST-LINK/V2 on Windows 10
Hello!I have Blue Pill board and ST-LINK/V2 programmer. When I open STM32CubeProgrammer on Windows 10, my ST-LINK is detected properly but nothing happens when clicking on connect. No error messages, nothing. I can click all day and nothing. At the s...
Resolved! Power on reset fails when I power a blue pill from batteries
Hello,I made a project using a blue pill. It works when is powered through st-link (3,3V).When I power this board from two AA batteries (~3V), the board does nothing until I press the reset button.An STM32F103 should work from 2 to 3,6 V, according t...
Resolved! blue pill STM32 PC13 LED is always ON
Hi there, I am using STM32F103c8t6 blue pill. there is a problem: when I use ST-LINK programmer to download the code to it, the PC13 LED is turned ON, without being ON in the program! why is that? One assumption is that the board is driving too much ...
Experiencing difficulties in creating a phase difference between two PWM signals
Hello everyone,I'm new to using STM32 boards and coding with STM32CubeIDE. I have a simple task: generating two PWM outputs and adjusting the phase difference between these two PWM signals at runtime.I'm using an STM32F407 board, and from what I've g...
Resolved! Pin-out of STM32H723 vs. STM32H7 Nucleo-144 boards
Dear all, I am trying to make sense of the pin descriptions / pin-mapping of the STM32H7 Nucleo-144 boards, vs. the MCU STM32H723 which it is equiped with.User manual UM2407 (rev. 4) of the board reads:pin PA3 has function ADC12_INP15pin PC0 has func...
how to set OCTOSPI1 of STM32L4P5G-DK as 1.8V instead of 3.3V?
Hello, Testing 3.3V Octo-SPI PSRAM is fine on the STM32L4P5G-DK board. I'd like to test another 1.8V Octo-SPI PSRAM now. The solder bridge options SB17/SB18 for PSRAM and SB13/SB14 for MCU are modified for the purpose. However, a certain DQ bit is st...
Issue with starting when power is disconnected from STM32L0
Hello, I am using STM32L0 microcontroller in my device. I put my device in deep sleep and wakeup using the same button by sorting SYS_WAKEUP2 pin and nearby PC14 is used as an Input pin (pulled-up). The issue is when I disconnect & reconnect USB po...
Resolved! I2C Mapping for STM32H750B-DK
I’m currently working on a project that involves I2C communication using the STM32H750B-DK but I’m having trouble identifying which I2C peripheral (I2C1, I2C2, etc.) is connected to the Arduino I2C pins (SDA/SCL) on the board.Unfortunately, I couldn...
Nucleo-H753ZI Power Supply through 5V
Hi everyone, I’m currently struggling to understand the behavior of the power line on the Nucleo-H753ZI board. My goal:The Nucleo board should be programmable via CN1 (Micro USB, ST-Link connection to PC). When connected, this should provide both 3.3...
