 		 #143646 - 1) Log computation, 2) LCD requirement
Hi,

1)Is there any way to caculate log (to the base 10) using assembly language in '51?

2) I am in need of a LCD panel (Not the character LCD module). The design required on the panel is slightly odd, it should show 3 1/2 digits and a few symbols in some corner. Most probably it will be a customized LCD. But still I am trying if any company has already made such LCD... Does anyone know of any company in India who manufactures or imports LCD panels?

Regards,
