The SD/TMRpcm disables the servo.

Hey…
My servo gets disabled by the TMRpcm
when I uncheck SD.Begin the servo works fine. But if its active the servo wont work. Any help? Thanks all.

I use Arduino UNO R3 Dev.

void loop(){
   SD.begin(SD_ChipSelectPin);
}

Rest of the code:

#include <Servo.h>
#include <Keypad.h>
#include <SD.h>
#define SD_ChipSelectPin 10
#include <TMRpcm.h>  

TMRpcm som;

Do not cross-post. Other thread removed.

Yes it will they both want to use the same timer. The solution is to use an external chip to generate the servo signal or an external sound generator.

SanderAkaTheGod · April 8, 2016, 1:21pm

Cool.
So you mean I need a "SD Card" to run code on the same board?
So how do I make the SD Card run the sound code?
Thank you very much!

No I don't, I am saying that because both libraries want the same hardware resource, one of the functions, either sound output or servo control has to be done with external hardware.
