Control device by three modes with variable output voltage by PWM for SL-series
laser head, head made by "RGB Laser System International", ATMEL AVR, 2006 year.
Based on ATMEL AVR ATTINY26L-8SI @ 8 MHz.
Features:
1. Two mode whith adjustable voltage level by PWM ( Pulse Width Modulation ).
2. Strobe mode whith adjustable timers parameter and adjustable voltage
level (by PWM) then adjusting voltage mode on.
Accuracy of times adjusting 256 / 8,000,000 Hz = 32 mc.second
3. Modes change by button "mode" in sequence: 1-st level voltage,
2-nd level voltage, strobe mode .
4. Based on ATMEL ATTINY26L @ 8 MHz from internal RC-generator.
5. Software: c compiler, code size 1484 bytes ( 742 programm words ).
