Hi sir,
Could you help us to suggest LED Driver?
[ask customer]
For the PWM mode LED driving controller for below functions:
Please tell me the method that you need to control the different LED color and brightness ratio of LEDs?
Exp.: From VCO or the utility which working under WINDOWS? I will talk with the chip vendor and provide you some further information, Thanks!
[Customer feedback]
Each color intensity should be controllable by 3 individual PWM signals.
The duty cycle of the PWM signal should be adjustable in 8-bit resolution (256 steps).
This can give 256x256x256 RGB color combinations. Available options would be:
1. Use a Windows driver to drive GPIOs in PWM mode. This methods requires a large number of GPIOs.
2. Use a separate LED drive chip such as PCA9633 by NXP (Feel free to find a better alternative). This requires a Windows I2C driver.
