MultiPin (timing?)-Problem when using setResolution()
stif opened this issue · comments
I am testing with the TwoPin_DS18B20.ino Example and both Sensors are working as expected.
But when i add following code in setup() function after sensor.begin():
if(sensor_inhouse.getAddress(inAdd, 0)) {
sensor_inhouse.setResolution(inAdd, 12);
}
if(sensor_outhouse.getAddress(outAddr, 0)) {
sensor_outhouse.setResolution(outAddr, 12);
}
the reading of the first sensor who executes the requestTemperatures
function is stuck (i get a response, but always the same value regardless of real temperature). the sensor which executes the requestTemperatures
function the line beneath the first one is ok. if i swap these 2 lines it is still the first sensor in code appearance which get stuck. eg.:
sensorX.requestTemperatures(); <- this sensor is stuck
sensorY.requestTemperatures(); <- this one is ok
Also it does not matter if the resolution is set to 9, 10, 11 or 12. If setResolution
is executed the first sensor who do a requestTemperatures
is stuck. If setResolution
is not executed, both sensors work as they should.
Workaround:
Just set the setResolution
and upload the sketch. Then comment out the setResolution
function and upload again. The Sensor will remember the resolution from previous upload and when the setResolution
function is not executed in the actual Sketch both Sensors work as expected with wanted resolution..
PS: I am working with latest PlatformIO and ESP32.
