I try to learn how to use OPAMP by testing the example code Examples/OPAMP/OPAMP_PGA/.The MCU board is Nucleo-G431RB.This is the case of OPAMP_PGA_GAIN_2_OR_MINUS_1: blue line is output by DAC and red is by OPAMP. My 1st question: why the amplified s...
I'm mounting my MCU on PCB. I have done the schematic referring from https://www.st.com/resource/en/datasheet/stm32l476je.pdf . Please help me verify this. My conditions are as follows.I am using 2 Digital sensors and one LoRa as communication module...
STM32G474RC，flash size is 256kB，default dual bank，so the flash size is 0x08000000~0x08020000, 0x080400000~0x08060000.If the code size is larger than 128kB, but the address is non-contiguous. How to store the exceeded programs into Bank2 automatically...
Hi, I'm working on an STM32H7 project with very fast (800 KHz) periodic interrupt. I've been looking at the generated code as I tweak the C source. I'm confused about the use of "volatile" for the global variables used by the ISR.I feel like I need...
stm32f103cbt6, i2c1 in slave receiver mode. CubeIDE, stm32f1 pack ver 1.8.4. I use HAL_I2C_Slave_Receive_IT to receive 1(adr)+2 bytes. I2C standard mode. Both err and evt interrupts enabled. I2C stucks into bus error (BERR flag). Jumping over HAL co...
Hello, is there a way that a timer triggers an I2C-Receive with a Datatransfer from the Peripheral to memory via DMA?I’d like to have no “Timer-Interrupt�? that calls the DMA-Transfer, invoking the I2C. I’d like to drive the DMA-Request from the Time...
Hi,I have a very specific question regaridng the functionalities of the STM32L4's internal bootloader. We are using its functionality to flash and validate our targets according to AN3155 and AN2606. This operates quite well. But now we came into the...
Hello there,I was trying to figure out a way of how to change the UART baudrate "in runtime" via HAL API for stm32f0. I failed to find a way to do it other than manually (copy out the functionalities used in the uart init function and change it accor...
In my customised board i am transmit "Hello World " via default arduino pins PA10=D0(Rx) and PA9=D1(Tx) named as USART1 using FTDI232 (USB to serial UART interface) and showing the trasmit data in the serial monitor properly. In my code i have writ...
