A0-A3 u mean is ADC0 till ADC3??(pin 23-26)...because pins 14-17 is for SPI right?....correct me if i am wrong...thanksARDUINO pins 14-17 a.k.a. A0-A3. Yes, they are pins 23-26 on the ATmega chip.
Hardware SPI is on ARDUINO pins 10-13 which are pins 16-19 on the ATmega.
If you are going to use the Arduino libraries you should probably get used to calling the pins by their Arduino numbers to avoid confusion. You can learn more about the naming here: Arduino Pins - Google Drive
thanks for good reference..i will refer it when i calling the pins. and now i use the code u provided to me. as you said:
#define ACCEL_CS A0
#define ACCEL_SCK A1
#define ACCEL_DI A2
#define ACCEL_DO A3
then which pins i should connect to with all these 4 pins?or because of soft connection. i no need to connect it through any hardware?i just define it with these four pins?
