ToothPIC Services Reference
ToothPIC Services are pre-installed in the protected memory region 0x0000 to 0xBFFF and are not available
if you choose to overwrite this memory. Certain functions are more suited to inline compilation and are
macros defined in the file ToothPIC.h.
Examples of the use of most services can be seen in the BlueMatik Diagnostic and ToothPIC Diagnostic
Firmware Solutions.
Analog I/O
ToothPIC’s PIC18LF6720 microcontroller supports 12 channels of 10-bit analog to digital conversion. The
ToothPIC Diagnostic Firmware Solution provides an example of its use.
The following macros are defined in ToothPIC.h:

Sets AD0 to AD10 as analog and AD11 pins as digital I/O
Sets AD0 to AD11 as analog inputs
Selects ADch pin for A to D conversion. A delay is required
between selecting the channel and starting conversion. As a rule
of thumb, call CyclesDelay16plus16times( 9 ) or consult
PIC18LF6720 microcontroller documentation
Starts A to D conversion
Nonzero until A to D conversion is finished
Does not continue until A to D conversion is finished
Places 8-bit A to D result in uData
Places 10-bit A to D result in uData
