NOTE:
will act as a LIN master; if D1/R4 are omitted, the node defaults to slave status.
This behaviour is more fully described in the LIN specification (reference 1).
This option configures the hardware as a Master or Slave. For complete master
or Slave status it is still necessary to configure the software appropriately.
The HC908EY16 Flash device can be quickly programmed on this Sample
board from two sources: the RS232 connector & the Cyclone Header.
If using the RS232 connector (P1), the following steps are recommended:
Once the Flash is programmed, code can be executed and debugged using the
CodeWarrior environment or the user may choose to disconnect the debugger
and run from Flash. Please be sure to select the correct crystal option and IRQ
configuration (typically J1 pin 1 – pin 2 connected) in either case.
If programming using the Cyclone (reference 3):
Again, code can be executed and debugged using the CodeWarrior
environment or the user may choose to disconnect the debugger and run from
Flash. If the Cyclone is used, it should be configured to provide the on board
clock.
1. Power down the board
2. Ensure that the Cyclone is disconnected
3. Remove the P4 pin 11 – P4 pin 13 connection
4. The canned oscillator should be fitted
5. Connect a serial cable from P1 to the serial port on the PC
6. Connect J1 pin 2 to pin 3 (connects high voltage to IRQ)
7. Power the board (via switch S1)
8. Launch CodeWarrior and follow the on screen guide (reference 2)
1. Power down the board
2. Remove the P4 pin 11 – P4 pin 13 connection
3. The canned oscillator should be removed
4. Connect J1 pin 1 to pin 2 (connects Vdd to IRQ – Cyclone will override
5. Connect the Cyclone to the 16 pin header (P4)
6. Connect the Cyclone to the PC as per the User guide (reference 3)
7. Power the board (via switch S1)
8. Launch CodeWarrior and follow the on screen guide (reference 2)
