Processor Include File

Recommended Posts

Hi Everyone, I am building my own 3d printer based on the design of my ultimaker original. The hardware is mostly finished and I am now in the process of finishing up the electronics. I have borrowed heavily from the UM v2.1.1 schematic but have made some additions of my own which means I need to modify the firmware to make it all work. I'm not new to this by any means. I've been writing code for 8051 variants for quite a while now using uVision 51 which still works great for these processors. I downloaded the Arduino IDE and the marlin firmware and now I'm completely stumped. I can't find any mention of the processor include file anywhere in the code (unless I'm just missing it). I see ports being called by name but there has to be a file somewhere which tells the compiler what the address is for that port.

Here is an example of what I am used to working with:

P1 Bit Registers

sbit P1_0 = 0x90;

sbit P1_1 = 0x91;

sbit P1_2 = 0x92;

sbit P1_3 = 0x93;

sbit P1_4 = 0x94;

sbit P1_5 = 0x95;

sbit P1_6 = 0x96;

sbit P1_7 = 0x97;

Any help would be greatly appreciated. Thanks.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
