Where can I find a reference manual for LPC17xx ?

Hello Guys,

I have bought a LPCXPRESSO1769 with cmsis-dap from embedded artists and I already spend a few days of research.

As always I wanted to start blinking the onboard RGB LED. I already managed to acces the correct registers with the library "lpc17xx.h" and toggle the appropriate pins with an example I have found online.

Before I go any further I really want to understand what I am doing.

The example uses the following registers and syntax:

LPC_PINCON->PINSEL7 = 0x000000;

LPC_GPIO3->FIODIR = 0xffffffff;

In the user manual UM10360 I can find the defintion of the PINSEL register and the function of FIODIR and the definition of the PIN CONTROL MODULE. But nowhere the syntax "LPC_PINCON->..." or "LPC_GPIO[n]->" is used. So how do I know what syntax to use in which situation? For me as a beginner the "lpc17xx.h" does not really help me. So what I am searching for is a reference manual with detailed syntax explanation.

I also tried to find such a manual for the LPCOpen libraries with no luck.

Can anybody give me a hint?

Your help is very much appreciated!

Best regards,

Denis

You already have the User's Manual. Perhaps what you need is to download the LPCOpen example code for the LPC17xx. See here:

Thanks and regards,
