Using TSP commands to set a buffer fill mode:
To set the testData reading buffer fill mode to continuous, send the following command:
testData.fillmode = buffer.FILL_CONTINUOUS
To set the defbuffer1 reading buffer fill mode to fill once, send the following command:
defbuffer1.fillmode = buffer.FILL_ONCE
To print the defbuffer1 fill mode setting, send the following command:
print(defbuffer1.fillmode)
Where a return of 0 indicates the buffer is set to fill once and a return of 1 indicates the buffer is set to
fill continuously.
Using TSP commands to set buffer capacity:
To set the testData reading buffer to hold 300 readings, send the following command:
testData.capacity = 300
