Hello,Still trying to get I2S working on the H7...Opened up PulseView to check the clock between another connected device...Much to my surprise, the STM32 is actually outputting 1.027 Mhz average clock pulses instead of the ESP32's 1.024 Mhz. Checked...
Hi everyone!, in my prototype i need some low and high pulse before sending uart datas.. How can i do this? I have already tried using HAL_GPIO_Write and HAL_DELAY and it is not worked.I need an advice for it.Thanks.
Hello,I have developed an application that saves accelerometer data when a machine starts up. This data is stored in the last page of the controller's memory (page 31).I'm encountering a HardFault exception that occurs intermittently, roughly 1 in 20...
Hello,I'm struggling with a really strange issue. I'm trying to make UART RX working on a STM32G4 custom board.I've followed the UART Interrupt tutorial. (https://wiki.st.com/stm32mcu/wiki/Getting_started_with_UART)I've tested it with Nucleo-G431RB a...
I'm using stm32f103c8 and PCA9685 devices. I'm trying to send data to PCA9685 via I2C bus. I send data using I2C_DR register. But when i write a data to I2C_DR register it sticks to it. After the data is send thee I2C_DR register should be cleared bu...
Hi, I've been working with my STM32F411CEU6. I connect my STM with BNO055 IMU sensor that use I2C as its communication protocol. Every time I press the reset button, the program should've start from the beginning, but in my case, that doesn't seem to...
I have a few questions about how the LPR works.First off, the RM says "Low-power run mode: This mode is achieved when the system clock frequency isreduced below 2 MHz."1. What is meant by system clock here? SYSCLK or core clock (HCLK)? As far as I ca...
Hi everyone, I'm using STM32G071 and my goal is to serial send data acquired by 4 ADC channels as fast as possible. In detail: I'm using DMA in circular mode to continuously acquire data from ADCs (ideally at 2,5MHz) and fill a buffer which is then s...
I have a STM32H747I-DISCO board and i have been trying to transmit some data via UART peripheral over the virtual com port of this board (Pins PA9 & PA10) for a couple of weeks now, but every effort failed. Initially i tried to write the code from sc...
When I assign a pin to a peripheral (e.g. comparator 3) the corresponding GPIO mode is fixed to Analog and cannot be changed. As a consequence, no pull-up or pull-down resistor can be inserted. By changing System.ioc with a text editor the correct c...
