TM4C1299NCZAD: How to power cycle cc2564

Part Number: TM4C1299NCZAD
Other Parts Discussed in Thread: CC2564

Hi,

We are using Tiva C TM4C129X board and CC2564 chip. We want to power cycle CC2564, for that we have written following code.

GPIOPinWrite(GPIO_PORTS_BASE, GPIO_PIN_1, 0);
delay_ms(20);
GPIOPinWrite(GPIO_PORTS_BASE, GPIO_PIN_1, GPIO_PIN_1);
delay_ms(200);

Are we missing any configuration? Or do we need to provide clock from outside?

Thanks and Regards,

Bhagyahri

    Hi Bhagyahri,
    What are you trying to do? Your code is first clearing PS1 pin and wait 20ms and then assert PS1. I don't see an issue with this. However, I don't see your initialization code. Did you initialize PortS and configure the PS1 to be an output pin like below? Can you use a scope to observe the PS1 pin?

    SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOS);
    while(!SysCtlPeripheralReady(SYSCTL_PERIPH_GPIOS))
    {
    }

    GPIOPinTypeGPIOOutput(GPIO_PORTS_BASE, GPIO_PIN_1);

    Hi Bhagyahri,
    I have not heard back from you. I assume the issue is resolved. I will close this thread for now. If you have new questions you can open a new thread or you can reopen this thread if you need further resistance.
