Swift version 5.1.5 (swift-5.1.5-RELEASE) prebuild binarys
Description
Im trying to read the value from a DS18b20 sensor.
The sensor is connected to pin 4.
with: cat /sys/bus/w1/devices/28-00000cb40e9c/w1_slave I receive:
c0 01 4b 46 7f ff 10 10 8f : crc=8f YES
c0 01 4b 46 7f ff 10 10 8f t=28000
So the sensor is fine.
I tried the 1wire example but it crashes when using .RaspberryPi4 in.
let onewires = SwiftyGPIO.hardware1Wires(for:.RaspberryPi4)! // .RaspberryPi2
let onewire = onewires[0]
Fatal error: Unexpectedly found nil while unwrapping an Optional value: file /home/pi/.../ReadDS18b20swift, line 2
Current stack trace:
Illegal instruction
When using .RaspberryPi3 it somehow works, but cant read anything:
["28-00000cb40e9c\n"]
Slave: 28-00000cb40e9c
Couldn't open 1-Wire device: /sys/bus/w1/devices/28-00000cb40e9c
/w1_slave: No such file or directory
Both issues causing this, missing Pi4 enum and unhandled \n in the 1Wire slaves list, have been resolved with 1754dc31e4d648c6999b3e664d8669d1a87c22eb , i.e. 1.3.9.
Board Type
Raspberry PI 4 4GB ram
Operating System
Debian Buster, TwisterOS (on both not working)

Anny ideas?
