Ok someone here was so kind to sugest ..."the SSC32 (32 PWM channels, RS232 or TTL control) is $40..." for my LED brake light project. Someone at the Lynxmotion Support forum said - "Eh, Not really." But then said I could read the manual to see if it would work or not. Well, that just exposes My ignorance!! :) Do all, most all LCD take the same Pulse widfth for certian brightness levels at the apporpriate voltage/amp level per each LED. Or, do each type of LED have their own unique PWM/voltage/amperage ratio for each brightness level? If I had ANY idea along those lines I would have better idea if the SSC-32 can do what I need it to do. The LEDs in question at the moment are 5mm High Flux Red LED (AlGaInP) with 2 each of these on each channel.
Am I being well too simplistic in my questions? I would need at least 3 brightness levels Low/Running, Medium/Braking and High/Attention for several brief flashes not sure if high sure be the rate high or an over drive.. would be Swell if I could have a fuller range of brightness levels, but not nessecary.
The 5mm High Flux Red LEDs have the following specs:
optoelectric characteristics: PARAMETER SYMBOL MAX TYP UNIT TEST View Angle of Half Power 2=F81/2 90 Degree Forward Voltage VF 2.5 2.2 V IF=3D20mA Dominant Emission Wavelength =FF D 630 nm Luminous Intensity IV 5500 mcd IF=3D20mA
Thanks!
