I'm trying to use an ee892 CO2 sensor in a project I'm working on. It uses a proprietary low speed derivative of I2C but it's not compatible with the I2C bus. Can you give me some ideas on how I could test to see if this thing is alive?
How do I strobe a pin to send a bunch of data then wait for a certain period for a reply before moving on? It's the waiting for the reply part that I'm having problems with.
