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

Code:
 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
