Thank you.

Hi,

Take a look at below wiki link:

Hi,

This example turns on EVM board leds.

I need to turn on specific GPIO leds :

• AC19 
• AE20 
• AB15 
• AA15 

How can I access them and turn them on >?

Hi,

As per C6657 EVM schematics, the above specified pins are used for TIMER OUT & UART.

• AC19 - TIMO0/GPIO18(DSP_TIMO0) 
• AE20 - TIMO1/GPIO19(DSP_TIMO1)
• AB15 - GPIO20/UARTRXD(DSP_UARTRXD_V1P8)
• AA15 - GPIO21/UARTTXD(DSP_UARTTXD_V1P8)

You shall use the GPIO0-15 for your case.

Please refer evmc665x_gpio.c & evmc665x_gpio.h source under ..\ti\pdk_C6657_1_1_2_6\packages\ti\platform\evmc6657l\platform_lib for usage.

Thank you.

Hi,

It is possible to turn on only leds GPIO0-15.

Am I correct ? 

Thanks.

Hi Ivgeni,

No, You can use unused GPIO pins for your testing. Please refer C6657 EVM schematics.

Thanks,

Hi,

I want to turn on GPIO18 GPIO19 GPIO20 GPIO21.

can I use this commands ?

gpioSetOutput(18);gpioSetOutput(19);gpioSetOutput(20);gpioSetOutput(21);

Should I write any other commands ?

Thanks,

Ivgeni.
