ThingSpeak channel fields are untyped. So there is no type configuration to set in channel setting. Instead, you just convert to the type you need after reading the data. In MATLAB, you can use the uint32 function. For example, the following snippet reads 5 minutes worth of pressure data from the public Natick Weather channel (12397), and convert them to uint32.
pressure = thingSpeakRead(12397,'fields', [6], 'Numminutes',5)
uint32(pressure)
We are curious about your use case for setting specific data type for fields. If you don't mind sharing, what are your main reasons for wanting to do so. Thanks!
