Examples

Write Value to an XCP Channel Characteristic

Write a value to an XCP characteristic and verify the value.

Read the original value.

a2lObj = xcpA2L('myA2Lfile.a2l');
chanObj = xcpChannel(a2lObj,'CAN','Vector','Virtual 1',1);
connect(chanObj);
charObj = a2lObj.CharacteristicInfo('torque_demand');
value = readCharacteristic(chanObj,charObj)'

     100

Write new value.

newValue = 200;
writeCharacteristic(chanObj,charObj,newValue');

Read value again to verify change.

readCharacteristic(chanObj,charObj)'

     200
