Transducter
Encoder/
analog
The
transducer is controlled by the 16-bit DSC dsPIC33EP.. . DSC includes
QEI
module that enable to evaluate with precision 1/4 periods even
quick incremental pulses of precision encoders. The 16-bit converter
DAC8760 provides voltage and current output. By default, the output
value varies in proportion to the distance from the starting point
(output 0V,4mA) to the end point (output 10V,20mA). Instead simple linear function
you can enter polyline from computer . In current mode, the converter
operates independently. The default values from computer are permanently stored in
the FEPROM of DSC.The transducer can be used as a slave of computer to
measuring the length and simultaneously as its analog output. At the beginning of program memory of
controller is located
bootloader, allowing to update program from your computer via
a serial line.
The control program for Windows in setting the
output is adapted to
datasheet of DA
konvertor. The card was put into operation in prototype form at
the one-sided PCB. The price of the card( already as a professional
printed circuit board) including the software is 35 Euro without VAT.
