   Hi,

   I am porting a lib from arduino. Previously in its header file it was written as <avr/io.h> now I changed it to just io.h but it says uint8 and uint32 not defined. How shall I handle this error?

   youthreewire - are you using the Maple IDE?

   The Maple IDE seems completely happy with compiling the Blink program with a couple of extra declarations (though I haven't uploaded):
   

   uint8 f = HIGH;
   uint32 g = LOW;
   
   void setup()   {
     pinMode(13, OUTPUT);
   }
   
   void loop()
   {
   
     digitalWrite(13, f);   // set the LED on
     delay(100);                  // wait for a second
     digitalWrite(13, g);    // set the LED off
     delay(100);                  // wait for a second
   }

   You could
   #include "libmaple_types.h"
   if those types are all you need.

   <avr/io.h> now I changed it to just io.h

   This will not work. The "avr/" part means it's an AVR-specific header. The Arduino boards are based on the AVR architecture, while Maple is based off of ARM. This means that code that relies on AVR-specific features (like those present in avr/io.h) will not work on the Maple.

   There is a file in libmaple called io.h, but that's just a coincidence. It has nothing to do with the avr/io.h header.

   Perhaps you can give us a link to the library? Maybe we can figure out what parts of avr/io.h it uses, and what the equivalent things are on ARM.

   Like it says in the Guidelines for Posting,

   If you want help porting a library (or checking if it works), provide a link to the library in your post.
