Cable Connector
Overview
Hardware Control Signal (TVDDEN)
QuickWriter's programming cable connector is compatible with existing PICwriter and Parallax
PIC16CXX-PGM programmer adapters while also providing Gang programming with TechTools
Gang programming adapters and In-Circuit Programming with the included ICP Cable.
A newer signal, TVDDEN is also provided on this connector for automated control of the Target
Circuit's power supply (see:
If for some reason the voltage condition can not be met, the operator can use the ABORT button
to close the dialog. Using the abort button will cause QuickWriter to discontinue the operation
and display a relevant error message.
TVDDEN can be used to control your target's power supply (through an appropriate driver
circuit). QuickWriter's TVDDEN signal will help automate control of the target's power and make
it possible to meet the required timing for power sequence specifications.
TVDDEN is a new signal, available on QuickWriter's 26 pin interface connector. It is not
available in the standard ICSP cable included with the unit. You may need to customize your
in-circuit cable to make use of the new signal (and add your power control circuitry). (see:
Connector)
TVDDEN is an active high, logic level (+-20ma) signal. Typically, one would use it to drive a
current limited LED within a solid-state relay to control your target's power supply.
