4.2 BL1810 Function Calls
4.2.1 I/O Drivers
The BL1810 contains four high-power digital output channels, two D/A converter output
channels, and one A/D converter input channel. These I/O channels can be accessed using
the functions found in the
4.2.1.1 Initialization
The function
library. This function initializes the digital outputs and sets up the driver for the analog
input/outputs. The digital outputs correspond to the Rabbit processor’s port E bits 0–3, and
the analog I/O uses timer B; bits 1, 2, and 4 of port D; and bits 6 and 7 of port E.
The function void
up parallel port D bits 1, 2, and 4 for analog output, port E bits 0–3 for digital output, and
starts up the pulse-width modulation routines for the A/D and D/A channels. Note that
these routines can consume up to 20% of the CPU’s processing power; the routines use
timer B and the B1 and B2 match registers.
4.2.1.2 Digital Output
The BL1810 contains four high-power digital output drivers, HV0–HV3, on header J4.
These can be turned on and off with the following functions from the library
HV0, HV1, and HV2 are open-collector sinking outputs, and are able to sink up to 1 A
(200 mA for the BL1810 and BL1820) from a 30 V source connected to the K line on
header J4. HV3 is a sourcing output that is able to source up to 500 mA (100 mA for the
BL1810 and BL1820) from a 30 V source connected to the K line.

CAUTION: Remember to cut the trace
NOTE: Failure to do this could lead to
between K and Vcc inside the outline
for header JP2 on the top side of the
Prototyping Board if you are supplying
K from a separate power supply. An
exacto knife, a precision grinder tool,
or a screwdriver may be used to cut
through the traces as shown in
Figure 7.
