Open srv-config opened 4 years ago
I can verify OneWire is broken on the IoT.
Just to draw some attention to this: I am encountering the same problem as srv_config. I'm quite sure it's also related to the missing support of the nrf52840 based boards in OneWire, as described in these posts: https://forum.arduino.cc/index.php?topic=673098.0 https://forum.arduino.cc/index.php?topic=643463.0
I'm depending on the open source community to contribute these I/O register defines.
Please feel free to volunteer. Or at least keep following this issue. Sooner or later someone familiar enough with the I/O registers in this chip will do it. Then testing & confirmation by other people using this board will be needed.
@PaulStoffregen isn't it already covered by #33 ?
The library kinda works, but after a few reads makes the whole Arduino crash.
I tried library 2.3.7 on Nano BLE and it did not work at all. After creating a support for the board (actually NRF52840) it works good.
@PaulStoffregen Shall I contribute it / is this of any interest at all?
Issue is related to Arduino Nano Sense BLE and DS18B20 sensor (waterproof version) are not working together.
What I tried so far. I performed a test on UNO to isolate possible powering and sensor fault. Test looked as follows:
Connection of DS18B20
Black > GDN Red > 3V Yellow > D2
Last two connected via 2k2 resistor (2k2 instead 4k7 as I use 3V).
Then, to exclude possible coding mistakes I used ready example:
Result? works perfectly fine.
Then I switched to Nano Sense BLE board. without disconnecting the sensor I just switched connection on board's end and attached GDN, 3.3V and D2.
Result, -127. When trying to find DS18B20 address the result is none.
I noticed there is few topics around internet regarding nano series and none are resolved. I found also IoT and Every has the same problem.
