VSP5610: VSP5640 LED2 control problem

kueimei Liu

Part Number: VSP5610

Hi Sir,

We have a problem with the LED control of AFE VSP5640, LED2 cannot control the LED on/off according to the state we set.

The AFE and LED control relative registers the following:

=================================================

LED_DRV_SET = 0x0CCC7

LED_DRV_DLY = 0x00044511

TG_OUT_EN = 0x00C61

STB_CFG = 0x00C40

LED1_TG_T0 =82 , LED1_TG_T1 = 1000 => Red LED can be turned on

LED3_TG_T0 =82 , LED3_TG_T1 = 1000 => Blue LED can be turned on

LED2_TG_T0 =82 , LED2_TG_T1 = 1000 => Green LED cannot be turned on

Please help confirm where the problem is.

Thanks!

Hi Kueimei,

I am not sure why the LED2 controls cannot turn on the Green LED.

Can you please share your board schematics (if you would like to share the schematics offline instead of the public forum, please let me know).

Also is it possible to switch the Green LED to channel 3 and Blue LED (working) to channel 2 and check if the LEDs can be turned on?

Hi Praveen,

Thanks for your reply.

Sorry, we are developing with Canon CIS modules, so I don't have the schematics.

Is there any other method we can investigate this issue?

Hello Kueimei,

Since I did not hear back from you, I believe you were able to resolve the issue.

I will close the post and if you have any pending questions, feel free to post them here.
