DLPC350 registers "Reset Value"

RY9983

Other Parts Discussed in Thread: DLPC350

Hello.

I am evaluating LightCrafter4500 using I2C command from external mcu.
I could read values in each registers from mcu.
Some values matched "Reset Value" which is described in Table A-1(dlpu010b: P51-52).
But, Some values did not match it.

I would like to confirm whether my read value is correct, or not.
Could you check this?

Blair-san,

Thank you so much for your reply.
I am using v1.1.0.

And, I updated firmware today from the link below.
But, it was no effect for the register values.

Hello RY,

Are you reading these registers immediately after you've reset the device or after the device has been operated?

Blair

Blair-san,

Thank you for your advise.
I have checked the register values during holding the reset button(SW1) on LightCrafter 4500.
But, I noticed that it is not true meaning of reset for DLPC350 from your advise.

Since I can not set DLPC350 to reset state without modify the LightCrafter 4500 hardware, I would like to close this post.
Thank you so much for your support.

Best regards, RY
