2.1
Operating the AS5263 Demoboard
The demoboard can be used only
•
As standalone unit supplied by a 9V battery or the USB connection
Connect the demoboard with one of above mentioned supplies. No other connections are required.
All AS5263 devices mounted on this demoboards, are un-programmed parts. Following settings can be chosen:
1.
Full range operation pre-settings: 0-360deg / 0.5V-4.5V / analog
2.
Full range operation pre-settings: 0-360deg / 0.5V-4.5V / PWM
3.
Free programming: 0-360deg / 0.2V-4.8V (reduced voltage range, due to the upper and lower failure band) /
analog or PWM
Mode selection
After connecting the board to the supply, follow these steps:
1.
By turning the magnet knob counter-clockwise a marker appears
2.
Select desired option and press button S1 to confirm
•
First and second option (pre-settings for analog and PWM) shows now the programming
parameters to be set. Confirm these settings by pressing S1 again.
The demoboard is programmed and provides now
a) the read back analog values on the header P2 at pin Vout and on the display. The display shows
“analog mode active”.
b) the PWM signal on the header P2 at pin Vout only. The display shows “PWM mode active”.
•
Third option (free programming) shows the start angle selection on the display. Chose the start
angle with aid of the magnet knob and press S1 again
(the angle is set in degree, the analog output
voltage in Volts and the PWM output voltage in % of VDD)
. Please continue accordingly, until the
display shows “analog mode active” or “PWM mode active”.
The clamping levels CLL and CLH are automatically set to the chosen start/end voltage levels.
Note:
As long as the demobaord is not active (in free programming mode only), one can return to main menu
by pressing button S1 for about 2 seconds.
Resetting the demoboard is done by disconntecing the supply!
