Dears:
The below picture is the system's diagram :
VSYNC(25Hz) and HSYNC(33KHz) are generated from FPGA and connected with 934'GPIO0 and GPIO1, then 933 received the signals and sends out GPO0 and Ghe PO1 to Sensor.
However, from the below testing pictures we can see the HSYNC of 933'GPI0 is not normal. It looks loosing some HSYNC's data.
And the below is VSYNC's testing result is similar with HSYNC's;
Btw, if using the VSYNC generated by 934(60Hz) is sent to 933, then GPO0 can be tested a stable signal of 60Hz. Then we are confused.
The other issue is about I2C.
MCU configures 934 and 933 by I2C which is OK, however, it will be failure to configure Sensor by MCU.
Testing the 934's SCL is 400kHz(MCU is master and works on 400kHz), but 933'SCL is about 100kHz, pls. refer the below picuters:
Could you kindly help to give some advice about the two issues?
