CAN question #112

Open ioukos opened 3 months ago

ioukos commented 3 months ago

Hello,

this may be a general CAN question, but I want to send requests to my heatpump in order to obtain data : like outside temperature for example.

1st try ; I just "read" to the Bus and wait but only get useless informations 2nd try : I send value to obtain data then wait and read, but never received anything. Is this the good method ?

thank you

sorry guys, 2nd is the right way.

in arduino, how to make sure I'm reading the value I requested to the Bus ? show I "if" on "sender id" and "content" of the data, or should I use filters ?
