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...
Resolved! STM32H747I-DISCO USB DFU Mode
Hey everyone, I'm working with the STM32H747I-DISCO board and trying to get it into USB DFU mode to flash firmware using STM32CubeProgrammer. However, the board isn't being detected, and I couldn’t find clear instructions in the documentation about h...
STM32H7B0 voltage scaling problem
Hello everyone!I've designed a PCB around the STM32H7B0 MCU (I've attached a screenshot of the relevant part of the schematic) for audio signal processing. I wanted to use the maximum clock frequency of 280MHz, but this requires the use of Power Reg...
Mic Interface Options on STM32H757I-EVAL
Can the STM32H757I-EVAL board accept microphone output in formats other than DFSDM or PDM?
Resolved! Microphones (ST-MEMS) part number used in STM32H757I-EVAL
Hi,I am working on a project using STM32H757I-EVAL. I wanted to know what the model number of the microphone present in STM32H757I-EVAL. In the user manual, I could just find it as ST-MEMS digital microphones. Also, does it support external microphon...
