L298N "output not set up"

Mycodo Mycodo Issue/Bug
1

Hi there, I’m sorry and I bet this is something simple, but I’m stuck.

I am trying to add an L298N with IN1, 2, 3, and 4 as BCM pins 17, 27, 22 and 23 respectively.

I added the Output and saved this pin configuration - I did not specify any Enable pins, as my L298N breakout has those as permanent jumpers that are manually set.

I rebotted the system after adding the Output, but I still can’t toggle any of the channels - I get the error “Output not set up”

My setup is pretty bare-bones - only Inputs are CPU and GPU temperature, and the L298N is the only Output. It’s a Raspberry Pi Zero W on standard Raspbian and Mycodo is 8.9.2

Here’s the log output right after startup:

…any ideas? Thanks in advance for any assistance you can provide!

The current iteration of the Output requires the Enable Pin to be set. I can make the Enable Pin optional, but in the meantime, you can set it to a pin not in use and it should allow the output to function.

Thanks so much for the super-quick solution, I knew I’d seen you say this somewhere before but couldn’t find it. Supplying some idle pins solves my problem and I’m back up and running, thanks again!

You’re welcome. And since I happened to have my IDE open, I just added the option to disable the Enable Pin. This is untested, but should work. Let me know if you test it and there’s an issue.
