4RO 4DI expansion module

Thokoane

Hello

I've recently bought two expansion modules from unipi. And would like to know how to communicate with both the modules using a one wire system. In my project i have the rasberry pi connected to the unipi and would like to add this two expansion module, this are 1w 4 DI 4RO expansion modules

Do you plan to use evok or what sw to read/set the IOs?

Hi

Out of curosity if am communicating with these two expansion boards do I have to have my I2C enabled on my unipi

Thokoane

When am using the owdir command am not able to detect the 2 expansion modules that I've connected on the unipi using the 1 wire system

Did you edit the /etc/owfs.conf file? It should contain the following:

!server: server = 127.0.0.1:4304
allow_other
server: port = 127.0.0.1:4304
server: i2c=ALL:ALL
timeout_volatile = 2

You will need to restart owserver for these settings to have effect. Or reboot the Raspberry Pi.

Can you post here the output of the owdir command? Please start with only 1 expansion module.
