following guide 3 kills guide 1 setup

[cmitcham]

after several years of on-again off-again lurking, i finally have a pi on the workbench for testing/learning reef pi.

smooth sailing through installation and adafruit guide 1 get me excited and i jump to guide 3 with a ds18b20 in hand. when i boot with the temp sensor, the pwm led dimming no longer works. the led is on at boot, but as soon as i touch the light slider it goes off and will not light again. the equipment on-off led still works fine, and the temp sensor works fine as well.

i shutdown and remove all the temp sensor set-up. still the pwm led does not work. i thought i killed the pi, but a start from scratch re-install got me back to a working guide 1. a second try at adding the ds18b20 repeated the problem.

should the setup in guide 3 (monitor only, no control) work together with the setup from guide 1? if so, any idea what i am doing wrong?

thanks for newbie help!

Checks the ds18b20 circuit. Does it work independently? Without led/equipment setup ?

the temp sensor works as expected.

a led on gpio pin 24 (equipment) still works fine.
a led on gpio pin 18 (jack + light) quit working when i added the ds18b20 circuit.

thanks for any help.

Well I don’t know anything about pi

Welcome to the Reef

check whats inside:
`ls /sys/bus/w1/devices/*`

reef-pi reads the temperature sensor from there, if theres a 28-xxxxxxx entry then its a reef-pi bug the sensor/linux is working fine. if the file entry is not present then its beyond reef-pi, something related to circuit or else is causing the sensor to drop out of linux .. which is beyond reef-pi (the controller software) and we have to look at physical circuit, boot config (one wire pin, pwm pin configs), reef-pi or dmesg log to see what happens at reef-pi software or kernel/device level when you hit this problem.

can you run those diagnostics and report back?
thank you for trying reef-pi, much appreciate you repoting back these issues.,

my original post was not so clear, and i have an additional 8 days of playing/learning now. it is not following guide 3 that kills the guide 1 setup, it is simply powering down the system.

the 1-wire bus and 5 ds18b20 sensors are working fine.

my problem is using the pwm0 pin. every time i shutdown the pi, i have to delete the light and jack and do the configuration again. i found another forum post

My reef pi build and errors (help needed)

Hello, I would like to share my build and problems with reef-pi, hoping that someone can help me solving. First of all i will explain my setup : Raspberry pi 3 B+ running every function i need on reef pi. I have been trying using many function over the years but the basics I always used is Power...

that sounds just like what i am seeing. unfortunately for me, his post also mentioned a temp sensor issue and all the replies he received only discussed the temp sensor.

my pwm0 jack and diurnal light is awesome, but i know if for any reason the pi powers down, i will have to delete and re-configure the light...

thanks for any further ideas.

apologies for not understanding, why you have to recreate the light after reboot?

Judging from the first post it’s because the PWM output no longer works, e.g. it is either stuck in on or completely off position.
