Hello,
you just need to have the right settings on the MODE pin. See 933 datasheet table 2, and the 934 datasheet table 2.
Also please follow the schematic example in 933 datasheet figure 31, and in the 934 datasheet figure 24.
Thanks for reply.
I used to have imx225 + 933 from external oscillator. When I connected the board, 934 had data output, but connected with isx 019 + 933, PCLK from imager, 934 had no data output. How should I configure the register.
below is the configuration
934:
0x01,0x04 0x03,0xec 0x4c,0x01 0x58,0x58 0x5c,0x5e 0x5d,0x34 0x65,0x72
933:
0x03 ,0xc5 0x05,0x04
You need to make sure you have the right settings on the 933 MODE pin to make it work with PCLK from imager mode.
This can not be made over registers.
Do you have stable LOCK?
It looks like you are not following the datasheet recommendation:
- It is recommended to pull GPO2 to GND with a minimum 40-kΩ resistor to ensure GPO2=LOW when PDB transitions from LOW to HIGH.
- At DOUT pins you need 100nF capacitors, not 220nF.
