Hello Picaxe Community
I've been banging my head against the wall about this one for a while, and it feels like there is an obvious answer. I've got two chips, 18M2 and 40X2, and I want to send data from the 18 to the 40. The 18 reads inputs, and the 40 set outputs, I've heard this is a pretty standard setup for people who need more pins.
My problem is that I can't get the 18M2 to talk to the 40X2 using SEROUT and SERIN, no wrong data, no corrupt data, just nothing is received by the 40X2. I have one OUT pin on the 18 tied directly to an IN pin on the 40, both chips have common ground (and common power). I have tried pull-up and pull-down resistors on the data line between the chips. I'm fairly confident that the 18M2 is sending the data, all I need to send is one variable, not a lot of data.
I feel like I'm pretty experienced when it comes to Picaxe chips, but this time I'm stumped. Can someone please help me?
