operation
Let us now create the actual program.
Appendix A.1, open the source file "main.c" stored in ”sample.prj”, and input the program
portion enclosed by dotted line in the figure below. Use the files other than "main.c"
without modification. After the input of the program, build the program according to the
procedure described in Appendix A.2. If an error message is output, check that the
content of the input program is exactly the same as the description shown in the figure
below.
automatically.
After the ACCEMIC MDE window appears, execute the program and check its operation.
For how to execute the program, see Appendix A.3.
The PPG count clock is set to 2 MHz, equal to the CPU operating frequency. The pulse
duration count is set to 0xFA (250) for both L and H levels. Therefore, the total count of
a cycle is 500, and the pulse wave at 4 kHz will be output. The pulse frequency is
calculated as follows:
PPG
2 MHz ÷ 500 (count) = 4 kHz
