Well, in part 1 I worked out that I could connect to the Gateway with a debugger. Now I need to work out a little bit about the board. It’s a 4-layer board, so tracing the signals isn’t that easy. Writing some simple code seemed to be the best way to determine what’s connected to what.
The easiest bit. I just toggled all the pins until i found out that the three green LEDs are all on port H. The link LED is bit 5, router is bit 6 and internet is bit 7. All are active high.
One switch is reset, so not much happening there. I can’t seem to determine what the other is doing yet. It doesn’t appear to be directly connected to a pin and may have circuitry between that and the reset button. I can’t remember what function it had on the Tado.
CC1101 radio, Ethernet, USB type A jack
Still to come.
Getting started with StellarisWare
I thought the easiest approach to getting somethings going was to try some sample code from StellarisWare – perhaps even some Ethernet code. Unfortunately the examples seem to only cover specific evaluation boards and I seem to hit a hard fault at some point running adapted code. Not getting really anywhere right now.
