p90ce201 problem
i have a problem
i need to solve a question : how it's possible to insert informations in a bus I2c.
When bus is in fonction, the microcontroller is dialing with all circuits that have I2c , if i want to ask with a circuit, how can i do ?
The microcontroller don't know me, i dont have adress II2.
When differents circuits want to ask to the bus they have to put the bus in that way "0" or "1" i don't remember exactly and after they can talk to the micro. I want to ask to circuits , to execute a command , and i don't want that the microcontroller know's me.
