Part Number: DS90UB954-Q1
Other Parts Discussed in Thread: DS90UB953-Q1
An image sensor connected to 953 ser(DS90UB953-Q1) and 954 des(DS90UB954-Q1).
Trying to pass the flash signal from the image-sensor to the deserializer.
953 gpio1 is configured as an input from the imager flash signal. Then 954 gpio6 is configured as an output gpio
and connected with gpio1 at 953. 953 and 954 are connected through a coax cable.
Using an oscilloscope we can confirm the flash from imager and gpio1 953. we don't see any flash signal at gpio6 954.
At 953:
setting gpio1 as input: reg 0x0E, val 0xC2
setting number of forward channel gpio: reg 0x33, val 0x01
At 954:
Setting gpio6 as output: reg 0x0f, val 0x3f
reg: 0xbe, val: 0x40.
Connecting gpio1 and gpio6 at RX port 0: reg 0x16, val 0x21
problem: the value at reg 0x16 becomes 0x20 after writting 0x21 to it?
What is missing?
