Hey z.f.k,

AXP209 is meant to work with Allwinner processor. AXP209 is controlled on the I2C line  (and there is a ready I2C driver for AXP209-Allwinner processor combination). If you use LPC1788 you have to write own AXP209 driver.

Another thing to consider is that it is a bit of bad choice to use AXP209 with LPC1788 since it provides a number of different voltages as output (as required for the Allwinner processors) and for LPC1788 you need just two. It is an overkill (that of course costs money).

I doubt there would be somebody that has tried to run it with the LPC1788, but the schematic would be your least problem! It is just normal power supply (that provides a number of voltages) + I2C control. I recommend you to refer to the schematics of our Allwinner boards that have AXP209 and are available at the Olimex GitHub page.
