I have my clock configured to external crystal 80MHz but accidentally I connected another board without crystal. STM32 started OK using internal oscillator at 4 MHz - HAL_Delay works fine, UART works fine but I2C is very slow. It looks like I2C HAL l...
I know this is a very basic question, but I want to know to decide whether the polling method is better or the interrupt method is better for time-critical applications.Kindly help me ...
Hello I Have stm32f107vct6 And I Want to send data from master to slave I2C Protocol . I Wrote Some code But it didn't work.Do you Have complete Example for i2c?this is my code Master:while(1){ while(!__HAL_I2C_GET_FLAG(&hi2c1,I2C_FLAG_BUSY)) HAL...
Posted on November 20, 2016 at 14:50Hi,I'am trying to get the audio from WM8994 line input.The BSP driver seems rather incomplete, it works with the 4 mems mics but not with the line input from the codec.Is there somewhere any source code example fo...
Each time I right click on the project and say Clean Project I get the following error: 21:15:14 **** Clean-only build of configuration Debug for project nrf24L01P_F407VGT6Disco_RX **** make -j3 clean make: *** No rule to make target 'clean'. Stop....
When I do an USB-FS Virtual Com Port application with them I face with "COM port does not open error". However when I try it another os(64 bits win7) I have no trouble at all.Here I attached a summary.Looking for any recommendation to solve, thank y...
I have custom stm32f765 board it has very minimal design. only some caps and resistor for the reset and boot. My problem is i have attached hse crystal of 16Mhz.this one https://www.digikey.in/product-detail/en/epson/TSX-3225-16-0000MF09Z-AC0/SER4069...
Hi,I've been trying to get I2S to work without using the HAL to get to know the MCU a bit more. I configured the Peripheral as mentioned in the reference manual, but whenever I write to the SPI->DR the status is stuck on busy.This is my init function...
I have configured my stm32g031 mcu as an i2c slave. My PC terminal is my master device and is connected to mcu via FTDI cable. When I do a i2c write, I can see mcu receives the data. But when I do an i2c read, I can see it reads 255 on my pc terminal...
