Using microcontrollers with more IO lines

Hi there,

In flowcode I can sellect several PIC microcontrollers with lots of Pins, for example a 18F6310 that comes in a 64 pin package.
For some projects I need some more I/O than the 40 pin PIC's have, so I need a larger version.
I can sellect the chip, and program it, simulate it with flowcode.
With Flowcode I use E-blocks to simulate and test in hardware.
However, for the larger versions, no hardware is avalable.

How can I program the software into the processor?
Do I need a (Microchip) in circuit programmer for this?

Is there a programmer (like the EB-006) avalable for larger PIC controllers?
Maybe a programmer where I can add a little circuit board with the processor?

Please let me know.
Best regards,

Rinie

Hello Rinie

You can use the Matrix EB006 and HP488 boards to program external circuitry. I have attached a picture of the connections that are required. You will have to keep the leads to your external board as short as possible. Around 20cm seems to be ok.

The 6 pin header goes to the following connections.

1 - MCLR
2 - +5V
3 - GND
4 - RB7 / PGD
5 - RB6 / PGC
6 - Not Connected
