Dear ExperimenterUK...

I am not able to upload the picture on this website. Crystal Oscillator with 4mm height and approx. 12 mm height I am taking about. I want to know which is better? And if both are of same quality why two different size are still present in the market?

One more thing I have observed is fast switching off and on of the controller makes the controller in the upset mode(UnEven behaviour at output pins) . To tackle this, I activated WatchDog in AT89S52, but it's not giving satisfying results. It reduces the number of time the system was in upset but still the system do go upset sometimes. How to tackle this issue?

Regards....

As far as I know the crystals work the same way.
Neither is better.

What do you mean by " fast switching" ?

hello! newbie here. i am kind of a guy who hates using ready - made existing libraries, so this helped a lot as i was trying to control and write to a character lcd display. however, i can't figure out how to set the cursor position. for example, i want to set it to the 5th column in the first row, so position 5. so according to the table, i am sending 10000101 on the 8 data lines of the lcd (register select pulled low). the cursor does not move there however. and i cant move the cursor left or right too. is it something wrong that i am doing? thank you.
