/*
* LCD contrast: controlled by pins 6,5,4,3 HD64461 GPIO port B.
* 6th is the most significant bit, 3rd is the least significant.
* 6th is the least significant bit, 3rd is the most significant.
* The bits are inverted: .1111... = 0, .0111... = 1, etc.
*
* We control the contrast value by setting bits in the data register
