Hi Simon Ford and Michael Wei ,
Thanks for the response for the power management of the MBED,
but from your result of the power down, the minimum power consumption
is still in 120-130 mA range, this is not way too big! if you look
at the CPU power management, the current is in the uA range. It
looks like there is a lot of peripheral components are still sucking
the current ... we will have to do better to bring the current
down to, at least by cutting it from 120 mA by half. Any thought
on this?
By the way, I used other ARM7TDMI CPU before (about 5 years ago),
the board is way big then MBED, and we were able to cut the power
to about 40 mA range. MBED now is 5 years younger than the old
one ... we got to do better on this.
I have saw some topics about sleep mode on mbed. but I still can't success.
I used "wait()" function to delay brfore and wait too much time.now I want use sleep mode replace wait() function.
I saw some said use sleep(int seconds) function work well.but i can't use sleep() function.why?
sorry my poor english.
best regards.
