It is enough to recover the core corresponding to the microcontroler and available in
the software page.
Another method consists in using the
emulator in combination with the
RS232 to ICSP interface which allows in addition to dialoguing directly with the FORTH kernel of the microcontroler.
Once the FORTH
kernel installed in the microcontroler, the applications can be
installed by using the FORTH interpreter via the RS232 interface.
This with the advantage of finding the flexibility of the FORTH but
remains tiresome in the event of development of the applications with
the disadvantage of a premature wear of the built-in memory.
Best is to use the
emulator
to develop the complete code containing at the same time the FORTH
kernel and the applications, of the safeguard and to download it in
only once time a new kernel.
Let us take the case of a small application developed on one
dsPIC30F4012.
This appication is small a chenillard on RE0, RE1, RE2, RE3, RE4 and
RE5 ports and of which speed is controlled by the RD0 and RD1 port
state (0 for 500ms, 1 for 375ms, 2 for 250ms and 3 for 125ms).
That it is with the
emulator or directly for the microcontroler, it is necessary to start by downloading the corresponding kernel
dspic30f.hex.
Then, it is necessary to interpret the pilot of the ports for dsPIC30f
ports_ABCDEFG_30f.txt.
It any more but does not remain to charge the following code:
DECIMAL
1 VARIABLE VOYANTS
1000 VARIABLE DUREE
( Instruction associated to the port D )

The instruction “LANCE” makes it possible to launch program “CHENILLARD” to the starting of the microcontroler.
