AM1806 VPIF H/W

H.ro

Other Parts Discussed in Thread: AM1806

I connect VPIF to VGA sensor(BT656 output) but I can't confirm D2-D9 signals.

I saw the signal on SCCB(SIOD, SIOC) by LogicAnalyzer.
And D2-D9 put the something signals(looks like BT656 format)

I assigned below
[VGA sensor] <-> [AM1806]
* D2-D7 <-> VP_IN(0-7)
* PCLK <-> VP_CLKIN0
* XVCLK <-> CLKOUT(27MHz)
* SIOD <-> I2C0_SDA
* SIOC <-> I2C0_SCL
* RESETB <-> GP6(10)
* PWDN <-> GP6(11)

Any error in H/W?

Hi,

I am not sure if I understood what you mean. Are you saying that you detect video signal on the sensor output, but you do not see the same video signal on the input pins of VPIF? If you don't see it at the VPIF input pin, it is HW; otherwise, it's probably your VPIF initialization.

Thank you, Mr.Yin

I'm gonna check VPIF initialization.
