Application Example 1—Low-Speed Stand Alone
NOTE
For a detailed description of how to download the code to the
EVB9S12XF512E, refer to Section 4 of the EVB9S12XF512E User Manual
(document number EVB9S12XF512EUM) included on the user
documentation CD.
Load the EVB9S12XF512E_StandAlone_LS.mcp project into the board. In this example project the
EVB9S12XF512E is configured to operate as an isolated board. Its local communication modules and the
input/output capabilities are exercised to allow basic tests of the EVB hardware integrity as well as
verifying the code downloading procedure.
The functions performed in this example project are:
•
Real-time interrupt configured to 500 ms period and used as the base time for the task scheduler
•
SPI master operating at 500 kHz
•
System basis chip (SBC) initialized in debug mode
•
FlexRay module configured for wake-up frames transmission at 1.25 Mbit/s
•
IRQ detection when SW2 is pressed; interrupt service indicated by toggling D26
•
Input capture IOC7 stimulated by SW3; interrupt serviced by the XGATE and indicated by
toggling D24
•
Microcontroller successive tasks are separated by 1 s intervals, the general-purpose LEDs are
continuously toggled by columns in this sequence:
— LEDs D22, D27, and D29
CAN cable
P&E BDM
multilink
DC power
