I read the accelerometer on a STM32F4-DISCOVERY board.
I wanted to have 40 samples /s and I got 40 messages displayed on the Terminal screen, after accumulating data on a moving average process.
print("X= "+accx+" Y= "+accy+" Z= "+accz+" [16bit]" );
accv_start = setInterval(function () { print(getAcc()); }, 25); // 40 Hz
acc_stop = setInterval(function () { clearInterval(acc_start); print(console.log("ACC STOP"));}, 1000); // stop after a while
As expected the timer behavior was pretty deterministic , having a minimum timer resolution of 1 ms.
Now my question is :
Are you going to improve the timer's resolution , I say in example to 10 us, in a near future ?
