TDA4VM: How to control GPIO in camera sensor driver?

qing li1

Part Number: TDA4VM

Hi,Ti members

We want to control some GPIOs in camera sensor driver(ti-processor-sdk-rtos-j721e-evm-07_01_00_11\imaging\sensor_drv\src\)

We want control GPIOs in IssSensor_PowerOn() of iss_sensors.c to control power and PDB pin of UB960

The GPIO we used is as attached jpg file(camera_GPIO.JPG)

GPIO driver is in the folder <root>/pdk/packages/ti/drv/gpio

You can include the relevant header files in imaging folder and call GPIO driver functions.

Hi,

Is there any sample to config the GPIO(such as MCU_OSPI0_CLK) and set the output value?

Thanks

There is no GPIO sample in camera SW. You should be able to find usage of gpio driver in other parts of the SDK.

I look at the routine and I don't know how it relates to the schematic,
Could you please give a general routine reference according to the above schematic diagram?
Thanks

Hi,

Sorry for the delay.

Please take a look at this E2E as a general reference.
