To set a blink cycle use the GRPPWM bar to select the duty cycle and use the GRPFREQ bar to select the blink frequency in Group Registers For example set the GRPPWM to OxE7 90 23 duty cycle and the GRPFREQ to Ox2F 2 second for a short blink every two seconds see Figure 7 Change the GRPPWM to 0x80 50 duty cycle and the LED will be on for one second repeating every two seconds Change the color of the LEDs by selecting a different PWM value for each LED 7 Setthe GRPPWM to 0x52 32 96 duty cycle and the GRPFREQ to 0x01 0 08 second and observe the pattern Change the PWMn values GRPPWM and GRPFREQ values to create different blink patterns Change the LEDOUT register on one LED output to be controlled only by its PWM for example LED1 controlled by PWM1 and LED6 controlled by PWM6 Change the blink rate and observe the results blinking with two different colors on each LED 7 Win I2CUSB Lite PCA9634 8 bit FM LED Driver HB File Device Options Window Help Mode 1 0x81 PWM Registers Group Registers Auto Increment All registers PWMO PWM1 PWM2 PV M3 PWM4 PWMS PWM6 PWM7 GRPFREQ GRPPWM Fl Noamal mode OxBF 0x50 0xE1 Ox7A 0x49 OxA2 Ox62 OxES Ox2F 0x80 Does not respond to subaddress 1 G Does not respond to subaddress 2 E ier eonim TAL a A La ae zt purs Kei lae ka Does not respond to sihaddress 3 E Responds to All Call addresses L
