  • Is anyone else having trouble with the sqrt(), log() and exp() functions in the Arduino environment? I tried to build a small capacitance meter with the Thing but when I use any of the above calls the ESP reboots. It appears as if there is a loop that takes too long to complete inside the these functions and the watchdog timer kicks the board out of the loop(). Any idea where/how to look into this?

  • Question from a newbie. I am considering the use of the TI MPC508 multiplexer: . I would like to know how much current I can drive through it to affect a load on its output. I looked through and it was not clear to me where that information lies in the datasheet. Can anyone help point this out or show how to determine/compute this characteristic? The input source will be 12V DC capable of 2Amps. The load is an inductor that requires 12V and generates 4.8 Watts (from the inductor’s specs).


No public wish lists :(
