37 There are two controller:
38 UC1611s 160x256
39 UC1611 160x240

41 Differences:
42 UC1611 0xa8 cmd: enables 80 display rows
43 UC1611s 0xa8 cmd: controlls graylevels
44
45 UC1611 0xc0 cmd: single byte command for LCD mapping control
46 UC1611s 0xc0 cmd: double byte command for LCD mapping control
