Programming Notes and Examples
Issue Date: 01/02/23
These functions set the active surface to the display indicated in the function name.
Before calling one of these surface selection routines, that surface must have been allo-
cated using any of the surface allocation functions.
None.
None.
This function enables or disables the Pulse Width Modulation (PWM) clock circuitry.
Enable Set to TRUE or FALSE to enable or disable PWM.
None.
This function enables or disables the Contrast Voltage (CV) pulse circuitry.
Enable Set to TRUE or FALSE to enable or disable CV.
None.
This function sets up the Pulse Width Modulation (PWM) clock configuration registers.
ClkSource The clock source for PWM; set to either CLKI or CLKI2.
ClkDivide The clock source is divided by 2^ClkDivide. Legal values for ClkDivide
are from 0 to 12 (decimal). For example, if ClkDivide
is 3, the clock source is divided by 2^3=8.
DutyCycle The PWM clock duty cycle; values can be from 0 to 255. A value of 0
makes the PWM output always low, and a value of 255 makes the PWM
output high for 255 out of 256 clock periods.
None.
This function sets up the Contrast Voltage (CV) pulse configuration registers.
ClkSource The clock source for CV; set to either CLKI or CLKI2.
ClkDivide The clock source is divided by 2^ClkDivide. Legal values for ClkDivide
are from 0 to 12 (decimal). For example, if ClkDivide
is 3, the clock source is divided by 2^3=8.
BurstLength The number of pulses generated in a single CV pulse burst. Legal
values are from 1 to 256.
None.
