Hi,
This is what we do:
1) MCU Init
2) Send DC setting to driver (the value is 63). at oscilloscope signals seems correct
3) Send GS settings to driver (the value is 4032). at oscilloscope signals seems correct
4) Start GSCLK with regular Blank toggles to reset internal counter
The result is that Driver generate un output ON of about 32 count of 4096
This value (about 32) remain the same changing DC or GS value in initial settings.
We can't understand what is doing wrong. Is there a reason that could explain that the drivers generate PWM but with a wrong and constant value?
Additional information:
A) GSCLK is generated by a PWM output from MCU. The signal is slightly rounded
B) SCLK / SIN / XLAT are generated "manually" by code but timing request seems to be ok. I'm going to change the software to use SPI for a try
Thanks
Luca
