Other Parts Discussed in Thread: MSP-EXP432E401Y,
Hi,
I'm using the MSP-EXP432E401Y dev board with CCS 11.0.0.00012. When running the TI-RTOS tcpecho example, It looks like the MSP432E4 is consuming 80mA while waiting for the next ethernet packet. Is that expected or is there a way to lower the power consumption? I was hoping the processor would enter a sleep mode and let a low-power section monitor the ethernet.
I measured the current by removing the Display commands (init, open, printf) from the example code, removing the debug jumpers on the board (rxd, txd, rst, tms, tck, etc) and the 5v jumper, and finally, replacing the 3v3 jumper with a small resistor and measuring the voltage drop across the resistor.
Thanks for any suggestions.
Josh
