Problem to display integer on LCD - folg...@yahoo.com - Jan 3 14:10:51 2009
Hello, I have a problem to display an integer on a LCD. I convert the integer into a
string. However, this apparently does not seem to work. The values are not displayed
properly. Sometimes the value is shon rigt, sometimes any other characters are shown and
sometimes the programm stops durig the conversion from int into a string.
The Integer takes values from 0 to 255.
Maybe somebody can help me and find the mistake(s).
Best regards

Re: Problem to display integer on LCD - Lennart Lindell - Jan 3 14:46:16 2009
Hi,
I can see two things that are wrong.
1. At end in IntToString (add termination of string):
str[j] = 0;
2. Change declaration of ausgstr in LCDOut_PotiValue to (declare a memory area instead of a pointer):
unsigned char ausgstr[8];

Re: Problem to display integer on LCD - folg...@yahoo.com - Jan 3 14:58:52 2009
Hello, I am using this code on an MSP430 (Texas Instruments). On the MSP430 it works fine.
I am able to display integers an a LCD. The Same code. I carried the code from the MSP to
the HCS12. I wonder why the code on the HCS12 does not work.

Your 'for' loop is messed up and when you add the closing parenthesis, ')',=
get rid of the ';' semicolon=20

Subject: [68HC12] Problem to display integer on LCD=20
Hello, I have a problem to display an integer on a LCD. I convert the integ=
er into a string. However, this apparently does not seem to work. The value=
s are not displayed properly. Sometimes the value is shon rigt, sometimes a=
ny other characters are shown and sometimes the programm stops durig the co=
nversion from int into a string.=20
The Integer takes values from 0 to 255.=20
Maybe somebody can help me and find the mistake(s).=20
Best regards=20

Re: Problem to display integer on LCD - folg...@yahoo.com - Jan 4 7:52:18 2009
Hello,
thank you very much for your help. It works fine now. I had to add termination of string and I declared a memory area instead of a pointer.
Best regards
