pimmel 5 Posted September 1, 2013 Share Posted September 1, 2013 Hey gang, In addition to trying to adapt some code into an Energia library for the SI570 I2C-controlled oscillator, I also have managed to get ahold of the Adafruit LPC810 mini-kit/programmer , with the intent to play around and learn something about working with ARM processors. Sick of using a breadboard, I soldered up on protoboard my own version  of NXP's LPC800 mini-board  and ran through the tutorials provided by Adafruit . I've also installed the Launchpad generic ARM compiler  so that I am not tied to an IDE like LPCXpresso  and have a little more insight under the hood of what is going on in the compilation/build/linking process. I found a nifty little simple blinky example that included an easy-to-modify makefile  and I was able to build and flash that on to the chip. So my question is, where do I go from here in the world of ARM? I don't really have a good understanding of the linker script, how/if you need to modify it, and I also really want to try and understand how to access the libraries that are included in the ROM on the die. Does anyone have any insight into that? All the LPC8xx examples I have found some to rely heavily on third party libraries that I can't follow or find, or (like in the example of the midibel stuff) are so arcane that I have a hard time trying to understand the code. I do have the data sheet and the programming manual, but they really seem to be geared for someone who has a bit of experience working with ARMs already, if not specific experience with LPC parts. All I seem to read on the googletubes is how easy it is to work with the NXP parts, not where you learn to use them So my embedded masters, do you have any hints or pointers?
