All of the PIC24FJ64GA004 family of devices power
their core digital logic at a nominal 2.5V. This may
create an issue for designs that are required to operate
at a higher typical voltage, such as 3.3V. To simplify
system design, all devices in the PIC24FJ64GA family
incorporate an on-chip regulator that allows the device
to run its core logic from VDD.
The regulator is controlled by the DISVREG pin. Tying
VSS to the pin enables the regulator, which in turn, provides
power to the core from the other VDD pins. When
the regulator is enabled, a low-ESR capacitor (such as
ceramic) must be connected to the VDDCORE/VCAP pin
(Figure 23-1). This helps to maintain the stability of the
regulator. The recommended value for the filter capacitor
is provided in Section 26.1 “DC Characteristics”.
If DISVREG is tied to VDD, the regulator is disabled. In
this case, separate power for the core logic at a nominal
2.5V must be supplied to the device on the
VDDCORE/VCAP pin to run the I/O pins at higher voltage
levels, typically 3.3V. Alternatively, the VDDCORE/VCAP
and VDD pins can be tied together to operate at a lower
nominal voltage. Refer to Figure 23-1 for possible
configurations.
i get a message saying check voltage
The dongle pic is 5 volts folks.

Like all Microchip PIC18 devices, members of the
PIC18F2450/4450 family are available as both standard
and low-voltage devices. Standard devices with
Enhanced Flash memory, designated with an ?F? in the
part number (such as PIC18F2450), accommodate an
operating VDD range of 4.2V to 5.5V. Low-voltage parts,
designated by ?LF? (such as PIC18LF2450), function
over an extended VDD range of 2.0V to 5.5V.

Walter,
When you get this figured out, then you can program a PIC for my dongle, ok?
Haven't bought the pieces yet, but want to have the dongle as backup for my Entec DMX PRO...

There are a lot of people who are also willing to program Lynx PICS for you Mschell.

now i get the message programing falied at program memory address 0x000000
