Hi
I need to poll some potentiometers and buttons through 4x 4051-multiplexers .. the potentiometers work well, but I have no idea how I would get if a button is pressed?
the first row-dials are the first 4051 .. works
the second row-dials are the second 4051 ..works
the third row are the buttons.. here i have no idea how to poll if it is pressed(?)
int i; // select y-input
void setup(void){
palSetPadMode(GPIOC,0,PAL_MODE_OUTPUT_PUSHPULL); // s0 Pin of 4051
palSetPadMode(GPIOC,1,PAL_MODE_OUTPUT_PUSHPULL); // S1 Pin of 4051
palSetPadMode(GPIOC,2,PAL_MODE_OUTPUT_PUSHPULL); // s2 Pin of 4051
palSetPadMode(GPIOC,5,PAL_MODE_INPUT_PULLDOWN);
i = 0;
}
void loop(void){
i++;
if (i == 32) {
i = 0;
}
palWritePad(GPIOC,0,((i& 0x01) > 0)); // write s0
palWritePad(GPIOC,1,(((i>>1)& 0x01) > 0)); // write s1
palWritePad(GPIOC,2,(((i>>2)& 0x01) > 0)); // write s2
int z = adcvalues[13]<<15; // ADC z-input
int z1 = adcvalues[14]<<15; // ADC z-input
int z2 = palReadPad(GPIOC,5); // ADC z-input
int z3 = adcvalues[0]<<15; // ADC z-input
switch (i){

}can someone please help me?
