Hi all,
I have following code
adc_t g4= GPIO4; void main(){ adc_init(g4);
while(1){ printf(“Value=%d”,adc_sample(g4,ADC_RES_12BIT);
} } My question is what is the step that i missed. It always prompt 4095 to screen. In my hardware design i made a voltage divider circuit with a 4.7k and a LDR. I measured ldr and it was 2.7 volts when sample results was 4095. Could someone satisfy an example or try to run my code in another device?
Is there an example for ADC in Riotos
