The LPCXpresso board
The board is $30 at Digikey. We have 2 of them. These boards could ship with either a LPC1768 or a LPC1769, so it's best to specify the latter when ordering.

serial EEPROM - 24LC64, 64k bits, address:50H (commands A0H & A1H), using pins 0-19 & 0-20, i2c1



Setting up the LPCXpresso IDE
Quickstart panel -> import project -> archive browse -> NXP ->LPC1000 -> LPC17xx
 * download, install and activate
 * create a workspace (a folder where all your projects are kept)
 * import the CMSISv1p30_LPC17xx and CMSISv2p00_LPC17xx libraries. (libraries seem to be called projects for some reason)

To figure out

 * inputs from radio receiver - pin change interrupts - done
 * i2c - done
 * motor outputs - done
 * UART - done
 * ADC - done
 * timers - done
 * interrupts - done

Misc.
It seems the ADC has some "issues"
