AT89LP2052 / AT89LP4052 V Control
An Atmel LP microcontroller monitors sensor cleaning
switching outputs are controlled with a small assembler programm and the
cleaning current is displayed on an 16*2 LCD. The
current is limited to 600mA by
hardware (LM317 regulator) and monitored by (low-cost) RC-conversion
between 500 and 250mA.
A picture of our prototype:
The Board can be flashed via AT89ISP
pinheader.The design supports 2 wire RS232 connection (RxD/TxD).
A small user interface with two buttons allows the user to select different
sensor signals and to start or stop the cleaning process.
