I need the schematic setup axp209 with lpc1788.please help me.. :-[ :-[


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.

Best regards,

However,I can introduce one module to another.I want to start by lpc1788 a lcd and the ability to charge and can be isolated from the power supply.Is there anyone to help me on this?
