CCS / TMS320F28377S : TMS320F28377S Power Save Problem

Kang Andrew
Prodigy 150 points

Part Number: TMS320F28377S

Tool/software: Code Composer Studio


I am communicating wirelessly to tms320f28377s using ZigBee.

However, the current consumption is 150mA.

Zigbee current consumption is 30~40mA.

I want to switch to sleep mode to save battery.

As a way to save battery, we need to be able to wake up when SCI interrupt occurs.

Below is the method I tested.

What is wrong?

1. When using this function :   __asm("IDLE"); 

- Wake up when SCI interrupt occurs in sleep mode. However, the current consumption is 120mA~150mA.

2. When using this function :  HALT(); 

- When SCI interrupt occurs, it does not wake up.

Thank you
