Other Parts Discussed in Thread: DM3730

Hi,

We will use Dm3730 in our project.The DSS Signals of Dm3730 will be configured by 24-bit, RGB888, 800(H)×480RGB(V).
We want to configure the dss_acbias "pixel data enable (TFT) output" polarity. (Active high or Active low)
Is it possible? If possible, how can we do it?
Thanks

Hi Ilker,

It is possible to configure the dss_acbias polarity by the DISPC_POL_FREQ[15] register IEO (Invert output enable) field. The default value of DISPC_POL_FREQ[15] IEO is 0x0 which means Ac-bias is active high.
You can read more details in the DM37x TRM chapter 7 Display subsystem.
