I have m Tsunami sound board connected to the Qwiic connector. I am programming in Python using the qwiic_i2c python library. I can read/write to the board, but its seems that the receive buffer is not clearing after I read the data. There is no flush() method in the library, so how do I clear out the data?
TIA
If there isnât a in-built function to use, the next step might be to try and create oneâŚI poked around 3 AI models to see if they had any code suggestions, and all basically suggested the same workaround: implement a âread until emptyâ function, hereâs a scaffold:
If no flush command exists, one workaround is to read all available bytes until none are left. Hereâs an example pattern in Python:
```
import qwiic_i2c
i2c = qwiic_i2c.getI2CConnection()
address = 0x10 # Example Tsunami I2C address
def read_all():
** data = **
** while True:**
** try:**
** # Read one byte at a time**
** byte = i2c.read_byte(address)**
** data.append(byte)**
** except Exception:**
** # Likely an empty buffer or NACK**
** break**
** return data**
cleared_data = read_all()
print(âCleared buffer:â, cleared_data)
```
This isnât elegant, but it works if the Tsunami doesnât provide a âclear bufferâ command.
Perpplexity also had an interesting suggestion of using a dummy read to clear it;
Perform a âdummy readâ to force the buffer to clear, even if the data isnât used:
** **with qwiic_i2c.getI2CDriver() as i2c:** ** _ = i2c.readBlock(device_address, register, buffer_size) # Discard the result** **
Those might be decent starting points 
Sadly, this flush code did not work.mAt this point, i have tried the i2c libraries from Sparkfun, Adafruit and smbus. None are without issues. At this point Iâm going with works, and stick to the serial interface.
Sometimes the old way is still the way! Sorry the others didnât work out
