Hi All,

I start with PICs and have some problems regarding LCD display.

For a 628, i wrote some lines of code to read a frequency in PORTA.4 and display the result after applying a formula.
The format of the displayed datas is like 0 km/h to 180 km/h

When the data displayed is for ex. 120 km/h and the next one 10 km/h i have the remaining m/h of the first data still displayed , so i have 10 km/h h displayed.

Do i have to clear the LCd before each display or format the data to have the same length to avoid this problem ?

Also, if i want to display a small cursor ( like || ) that would move on the line like a bargraph, how can i create and display this ?

Is there a tutorial about LCDs somewhere ? I didn't find it.

Greetings from Corsica, Patrick.
