When I try to comple I got error:

"#error directive: "CMSIS Target not recognised"" in file "lib/mbed/cmsis.h"


#include "mbed.h"
 
PwmOut servo(p21);
 
int main() {
    servo.period(0.020);          // servo requires a 20ms period
    while (1) {
        for(float offset=0.0; offset<0.001; offset+=0.0001) {
            servo.pulsewidth(0.001 + offset); // servo position determined by a pulsewidth between 1-2ms
            wait(0.25);
        }
    }
}

Do you have any other libraries in the folder of your program? I dont think it should compile them if they aren't included, but it doesn't really make sense it tries to do anything with cmsis, that should be completely unrelated to this program.

Hello Roman,

click on mbed library in Your project and on righ side click Update. This should do the trick.
