The EVM is designed for custom
function addressing core functions. In order to provide a certain level of
flexibility to the kit to perform or facilitate certain functions, certain test
ports are provided on the control mother board. They are shown in Figure 3-10.
Figure 3-10 General Purpose
J18 and J25 are the test ports. They provide limited flexibility as given
- J18 - It can be connected to a
potentiometer to provide a variable voltage to an ADC input of C2000. This can
be used to control the blower fan speed as the silk screen indicates.
Alternately, this analog input can also be used as a means of feeding in
variable input for any regulation purposes during development.
- J25 - It can provide two
- QEP port - interface to a
QEP for bench testing with a different motor for evaluating certain
- SPI port - interface to
any external SPI connectable devices
