Hi,now I'm implementing i2c with 1 master(U575ZI-Q) and 3 slave(L432KC) boards. master transmit dataBuf to slave HAL_I2C_Master_Transmit_IT(&hi2c1, addr<<1, dataBuf, sizeof(dataBuf)); and Slave receive it.HAL_I2C_Slave_Receive_IT(&hi2c1, dataBuf, siz...

Hi,I now implementing i2c with 1 master (U575ZI-Q) and 3 slave (LK432KC).I confirmed my code. It worked well.but after changed title of the project and deleted some project, it made me confued,, so I made every(1master 3slave) project new. Here is th...
Hi,I want to use random number.But, the same random number is generated each time it is run.When I debug the code below, W change with the same pattern every time I debug. What's the problem and is there any solution to make random number which is no...
Hi,I now implementing i2c with 2 stm board.The process is 1. Master transmit data 2. Slave receive and calculate some functions.3. Slave transmit that changed data4. Master receive it.with HAL_I2C functions.  I measure the SDA line with logic analyze...
