LM320240 Topway LCD Sample Code

Dear All,

I test my LM320240 LCD from Topway using this code i get from manufacturer. I have some question on that:

1. What tool used to convert bitmap to hex for the code. I have tried many tools from internet, but there is nothing compatible with the code. I found FastLCD v1.2.0 that almost compatible, but it do not support 320x240 controller, causing bitmap incorretly positioned at x direction.

2. The code using AT89S52 that has 8KB flash memory. After compiled, the code has 28KB hex. How to download it to AT89S2. Now, i am using flash programmer.

Thanks a lot for any help.
Regard.
