I’m trying to change the output current writing configuration code in special mode.
I have three drivers TLC5916 working cascaded. I’m able to read status code and I don’t have any problems to switch on and switch off the leds. However, I can’t change output current modifying configuration code.
As the circuit has three drivers, I send 24-bit configuration code. I’m attaching an image which shows "switching to special mode", "writing configuration code" and finally "switching to normal mode".
I’m really sorry but I can’t save an image with time data.
Is there something wrong with the sequences? Should I wait any time after writing configuration code? Is positive pulse of LE sent rightly?
