GPIO Control

Other Parts Discussed in Thread: TVP5150

Team my customer is trying to use the following lines of code in the TVP5150 driver to control the device “power down” and “reset”, but the pins do not change state, what could be the problem?

 

#define TVP5150_GPIO_RESET          24

#define TVP5150_GPIO_POWER_DOWN     23

 

gpio_direction_output(TVP5150_GPIO_POWER_DOWN, 0);

gpio_direction_output(TVP5150_GPIO_RESET, 0);

 

gpio_set_value(TVP5150_GPIO_POWER_DOWN, 0

    Chris,

    we are not familiar on how the Driver is set up or how it works in the HW apps team.  I will move your post to the PSP/LSP area as they should be able to know more details on how its should work and why it isn't working for your customer.

    regards,

    miguel
