Hi

I want use 50 attiny's as slave for a school project, but an attiny only has 2 digital outputs, which you use for the softwareserial, but you also need a 3th output for your max485?

Hi Florvis,

The exapmle schetck you can find on the project page should work as is.
Please try it! If not, you can run SoftwareSerial on pin 3,4 (you have to
modifiy SimpleModbusSlaveSoftwareSerial.cpp) and use pin 0 as direction.

Please give it a try (without and with fixing) and eventually file a bug!

Thank you!

I did not know I could use the adc pins as outoup pins, but now I know it is possible.
