Hello sir,
One of my customers is using SN65DSI86 for their face recognition payment project with 400Ku/Y runrate. The attached is datasheet of the panel used in this project. Do you mind helping provide set-up in DSI TUNER tool according to the panel's datasheet?
Besides, may I also ask about a questions related to SN65DSI86:
Can the GPIO port 4 of SN65DSI86 be used as PWM? NCP_LM156LF1L02_Spec_Ver_03(熊猫)new(1).pdf
Hello David,
May i ask for the clock setting of SN65DSI86?
When the input (MIPI )'s CLK is considered as a REFCLK, Pin_A7 connects to GND:
1) How can we select CLOCK for DACP/N Frequency Selection (12MHz, 19.2MHz, 26MHz, 27MHz...)?
2) Original setting in example shown in datasheet is : GPIO[3:1]= 3'b011 is 27 MHz，1080p 60 Hz. How can we adjust this CLOCK setting for different resolution LCD?
Best regards,
wenting

1. When using the REFCLK as the clock source, any DSI Clock frequency is supported, but if the clock source was instead the DSI A clock, then the required DSI Clock frequency would need to change to a frequency supported by the DSI86. When operating in this mode, any one of the following DSI A clock frequencies can be used: 384 MHz, 416 MHz, 460.8 MHz, 468 MHz, or 486 MHz. I would recommend using the REFCLK as the clock source so you are not limited to a particular DSI A clock frequency.
2. REFCLK frequency does not change, you would change the DSI A clock frequency to make sure the DSI A clock frequency meets the new resolution requirement. For calculating the DSI clock frequency, please refer to this app note:
