Part Number: TMS320C6678

Hi，

I am using a custom board having 6 6678 on it.

I want to give each DSP an ID and I am about to use GPIO to do it.

Now I can read 0x02300020(GPIO register IN_DATA) and get the GPIO status that I set.

I want to know is there some example or code about GPIO read or write ?

Hi
i think pdk functions better than reading register directly

GPIO API :
C:\ti\pdk_c667x_2_0_2\packages\ti\drv\gpio\src

GPIO example:
C:\ti\pdk_c667x_2_0_2\packages\ti\drv\gpio\example\led_blink

i hope this files help you

Ebi,
thank you for quick answer.
I can not find GPIO example in C:\ti\pdk_c667x_2_0_2\packages\ti\drv\gpio\example.
There is only Module.xs file in C:\ti\pdk_c667x_2_0_2\packages\ti\drv\gpio\example.

Best Regards
Jin

i don't know why you haven't GPIO_LedBlink example in example folder (TI employee can help you better )

i attach simple gpio example test project

GPIO_InOut_test.rar

i don't remember detail of this project (i use this about 2 years ego) . this code read and write gpio and write for c6678 EVM but you can find function declaration in evmc66x_gpio.c file
