Sending text to GLCD using BV4511 interface

[Scampy]

Received a 128 x 64 GLCD with touch screen from MikroElektronica that works fine with the EasyPic5 demo - so I know it's working.

Breadboarded the BV controller to the GLCD carefully noting the pin mapping as the Mikro screen does not use the same pin outs as the board. It powers up, displayed the default message and I can turn off the screen and backlight by sending the appropriate code and value to the I2C address

 BVCmd = $6
opt=1

i2cwrite SDA,SCL, BVAddr ,BVcmd,opt

But trying to produce anything graphical like turning on pixels or drawing boxes fails so I tried my other piggyback board. It to powers up, displays it's demo screens. However reading the limited "manual" (http://www.digole.com//images/file/T...ter-Manual.pdf) it doesn't have the same type of command set, more for hyperterminal....

Would welcome suggestions as to how to configure this puppy to use it's internal fonts to give me the equivalent of an 8 x 20 LCD as I've not only gone grey with this, but now getting bald

Ok I gave up with the BV4512 board and the I2C connectivity of the Digole board, and stested the Digole board in default serial mode.

It took a while but it works.

Having the built in selectable fonts makes this behave as if it was a large LCD - which for now is what I'm after.
