Hi I have done the analog to digital conversion in lpc2138.the thing is i need to display the digital data in lcd . the adc data will be in hex format (0x1FD) and that will be stored in the data register on adc . in order to display that using character lcd the HEX data has to be converted in to ASCII . i dont know how to do that. coding is done in c using keil tool.
Thanks in advance
Interesting that you write "even that was not working".
Even what? Your first attempt did add the value zero - and your math book already told you that addition zero to a number isn't expected to do any big magic.
Your second attempt you added 0x30 - you can write '0' instead unless you find it too readable to use actual characters.
But the big question is: you say it isn't working. But you don't say what is happening and what you expected to happen.
a = 0x000003A2; // = 930 decimal b = a%10; // = 0 decimal b = b+0x30; // = '0' a = a/10; // = 93 decimal c = a%10; // = 3 decimal c = c+0x30; // = '3' d = a/10; // = 9 decimal d = d+0x30; // = '9'
You unhappy with '9' '3' and '0'?
