LPC4088 I/O assignment

grahamsewell — Thu, 26 Mar 2020 09:28:52 GMT

Hi, I am working with the LPC4088 and I have the EA mbed project as a start-point but I am trying to reallocate some of the I/O. I can not find how the I/O is currently allocated e.g. how does a certain LCD driver pin get assigned to a particular function. I have exported the mbed project to Keil uvision5 and this builds ok.

I have found parse_pins.cpp which contains the following:

#elif defined(TARGET_LPC4088_DM)
static const PinName pin_names[] = {p1, p2, p3, p4, NC, NC, p7, p8, p9, p10, p11, p12, p13, p14
, p15, p16, p17, p18, p19, p20, p21, p22, p23
, p24, p25, p26, NC, NC, p29, p30, NC, NC
, NC, NC, NC, NC, NC, NC, NC, NC, p41, p42, p43, p44, p45, p46};

but have not been able to rationalise this against the functionality.

Any help would be much appreciated.

Best wishes and good health to all!

Graham

Hi Graham Sewell,

Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
To provide the fastest possible support, I'd highly recommend you refer to the LPCOpen library to learn how to configure the I/O pin properly.

Have a great day,
TIC
