Part Number: TLC59116

Hello,

I work on TLC59116 LED driver and I want to drive group pins (for example pins 0, 1, 2 and 3) using register GPRPWM, I write value in this register, but my LEDs don't light. Can someone help me with this problem ?

Best regards,

Nikola

Hi Nikola-san,

Would you post your schematic and register sequence in the thread?

Thanks!

This is my schematic for this device. And my I2C interface working very well. When I write same value in register GRPPWM, after that I read same value which I wrote. But my group LEDs don't work. I do not see in the datasheet that it is necessary to another another register.

This is my schematics:

Thanks

Hi Nikola,

Would you try the attachment sample code?

Thanks!

Hi,
Thanks for your effort to resolve my issue. I applied same configuration from source file, for register MODE1, MODE2, GRPWM and LEDOUTx(x = (0, 3)), but my group brightness functionality still don't work.
Thanks,
Nikola

Hi Nikola,

Could you post all your register value for the double confirm?

Thanks!
