Our customer is doing the product design using i.MX287 currently.
Their product is used with 3.5 inch LCD (320x240).
They are going to set the LCD Reflesh-rate to 90Hz.
However, they see 56Hz Reflesh-rate.
Setting the following in DOTCLK mode
- HW_LCDIF_VDCTRL0.HALF_LINE = 0
- HW_LCDIF_VDCTRL0.VSYNC_PERIOD_UNIT = 1
Is Reflesh-rate correct at the following understanding?
- Reflesh-rate = HW_LCDIF_VDCTRL1.VSYNC_PERIOD x HW_LCDIF_VDCTRL2.HSYNC_PERIOD x Period of CLK_DIS_LCDIFn
Is there any point that something must take care about others?
