Programming AccessTouch
AccessTouch
microcontroller by inserting the TEAclipper into its
connector. The circuit must be powered and the
TEAclipper must be held in place until the LEDs
stop flashing and the green LED glows steadily.
The voltage Vdd during programming must be
4.5V – 5.5V.
Since the programming time is very fast, no
programming socket is required for the TEAclipper.
It may be leaned against five plate-through holes
as depicted in figure 4.
Evaluation Board
An evaluation board is available for AccessTouch
consisting of a pre-assembled board containing all
circuitry except the Set switch, lock driver and power
source.
Product Blueprint
The evaluation board Gerber files and other construction
information are available as a product blueprint in return
for a signed Nondisclosure Agreement.
