Hello guys, I have been programming an ATMEGA16 using Atmel Studio 7 in assembly so far and I am now moving in C. The project I am on is not that hard but I fell into a minor problem. I have a simple function that takes a 16bit uint and only contains a switch. I noticed that it only works for the cases that involve the 8 LSB of the 16bit uint while every other case just goes to default. I suppose this has to do with the fact that ATMEGA16 is an 8bit controller and the switch involves a comparison which only occurs for the 8 LSB. Of course the simple solution would be converting my 16bit number into 2 8bit numbers and having 2 switches instead. So my questions are:
1) Atmel Studio really does not support comparisons with 16bit integers or it can be done with maybe some type casting?(I did try some type castings but I seemed to get the same result every time)
2) If it is not supported is there a smarter way than converting the number into 2 8bit numbers?
3) Is there an option that makes it show warnings for that? (which in my opinion should show up in the first place)
I am also attaching my code. Thanks for your time! 
uint8_t keypad_to_ascii_single_switch(uint16_t keyspressed)
{
switch(keyspressed)
{
case 0x0001:
return 'E';
case 0x0002:
return '0';
case 0x0004:
return 'F';
case 0x0008:
return 'D';
case 0x0010:
return '7';
case 0x0020:
return '8';
case 0x0040:
return '9';
case 0x0080:
return 'C';
case 0x0100:
return '4';
case 0x0200:
return '5';
case 0x0400:
return '6';
case 0x0800:
return 'B';
case 0x1000:
return '1';
case 0x2000:
return '2';
case 0x4000:
return '3';
case 0x8000:
return 'A';
default:
return 0;
}
}
Thank you!!!!! And now I must ask... I thought that when you create a pointer to a uint16_t it is automatically assigned an address which is obviously wrong. How do you assign an address to the pointer?
