CC2530/CC2531 Development/Evaluation Kit Hardware Analog Inputs

Other Parts Discussed in Thread: CC2530, CC2530EM

I am trying to build a project utilizing the Zigbee stack, and readily available hardware. I have been looking at the CC2530/31 development kits closely, and have a question about the available inputs. Reading the data sheet on the processor indicates that the ADC on the chip resides on port 0. Looking at the application notes on the development kits hardware seems to indicate that none of the lines from the adc are connected to the SmartRF05 battery board, or the more complex demo board with the attached LCD display. I need access to at least three of the analog inputs to complete my project. Are those inputs made available on daughter board which holds the processor or not?

Any help would be appreciated.

Thanks

You may want to lean more toward using the SmartRF05BB over the SmartRF05EB because the EB is full of gotchas with all of the connections to RS-232, joystick, LED's, etc. The BB schematics are also a little easier to follow than the jumping back and forth between the CC2530EM and CC2530EB schematics which is necessary. The basic trick is to trace the pin you want from the CC2530 to the EM connector where you will find its "schematic name" - for instance on CC2530BB, the P0.7 becomes known as EM_P1_17. You will be able to pick this up on the debug connector pin I/O A, pin 17 (17 is a convenient coincidence here - the EM pin number rarely corresponds to the debug connector pin number.) So there is one ADC input. Another easy two are P0.4&5 because they go right to the P4 connector isolated on the CC2530EM itself. How's that for starters?!
