Hi all,
I'm trying to get my head around how i address/control several i2c devices using a 40X2 and with hi2csetup & hi2cout commands.
I'm currently controlling some LED matrix drivers quite easily (Holtek 16k33 driver chip).
However, i want to place 2 (or more) of these LED matrices onto the ONE i2c bus.
From what i read in picaxe tutorials, It seems that i need to change the address numbers in my hi2csetup command each time i want to control a different device on the bus. Am i reading it correctly?
I thought the destination address would be sent in the hi2cout commands.
Can someone please share a preferred method to control multiple i2c devices on the ONE i2c bus?
Thanks in advance.
