Revision 2:3604f34e944b, committed 2015-03-26

Comitter:
mdu7078
Date:
Thu Mar 26 08:10:08 2015 +0000
Parent:

Commit message:
Fixed issue with display starting out as "0000" which was due to the fact that a table lookup is not necessary for initializing the character values since these characters are looked up in the LUT already (redundant call).
