Hello Everyone,I am trying to interface MPU6050 with STM32L072Z and while communicating to I2C line I am always getting constant value, bellow is the codevoid Serialprint(char *msg){ uint16_t msg_len = strlen(msg); HAL_UART_Transmit(&huart2, (uint8_t...
Hi All,In our product we have to avoid HSE, so decided to use MSI in PLL mode.The below code snippet works fine for MSI in PLL-mode , when auto-trimmed with LSE.But if the battery is say removed (The battery can get depleted in the field), the accura...
I am using nucleo board to test the functionality of USART2 and i am able to transmit data successfully.Now, whenever i restart the nucleo-board or restart debugging, it Transmits last sent buffer again even though the USART is disabled..I want to ...
Hi,I've an application where I'd like to use LSE in passive mode driven by a slow (1Hz) signal.When testing bypass mode LSE with slow clocks, I observed long delays between startup (cold start) and LSERDY being set by hardware. When measuring that de...
Hello,I am currently using a STM32F429ZI-DISC1 Discovery Board.I tried to get a UART tranmission going through CubeMX/HAL Drivers. Transmitting data works perfectly fine but when trying to receive any data I don't have any chance. So I was looking ov...
Hello, maybe it's not the right place to ask this type of questions, in case I apologize.While trying to understand how ARM assembler works, I came across this problem and I'm currently struggling to find the answer.Before explaining better my questi...
Hello everyone!I have 2 fixed PWM of 40kHz (TIM1_CH1, TIM1_CH1N) and one modulation at 80 kHz fitted into the others, matching the steps by zero.Instead of this, I have this signals:There is a gap between them of 1us.This is the timers declaration: v...
I have a setup with a STM32L452 Nucleo-64, and has connected a CAN transceiver to it. This is in turn connected to a CANDO dongle to a PC. With the current setup I'm currently able to transmit data from the STM32 to the PC with no fail. The reception...
I am trying to adapt some code generated in Cube-MX for use on the STM32F4RG used in two very similar projects. The code was written for a drone flight control board and the oscillator used https://www.digikey.com.au/product-detail/en/murata-electr...
I'm using i2c to connect MPU6050 in asynchronous mode (means interrupt driven). I've implemented dfa for that. Everything works fine, but there is strange interrupt right after Re-Start. SR1 == 0. Right after second read of SR1 there is right value (...
