Why did they break this? With a quick look at the schematic there's no obvious reason the SPI could not have been run to D11-13. Then MEGA was released and this was no longer true. I've no problem with that, I think it's done a great service to the geek world. I guess the target demographic for Arduino was (is?) less technical people who wouldn't know JTAG from JAG. #define CAPTURE_USE_TIMER5 // ICP5 is pin 48 #define CAPTURE_USE_TIMER4 // ICP4 is pin 49 #define CAPTURE_USE_TIMER3 // ICP3 is not connected #define CAPTURE_USE_TIMER1 // ICP1 is not connected In FreqMeasure FreqMeasure Library, for Measuring Frequencies in the 0.1 to 1000 Hz range, or RPM Tachometer Applications // Arduino Mega #define COUNTER_USE_TIMER5 // T5 is pin 47 #define COUNTER_USE_TIMER4 // T4 is not connected #define COUNTER_USE_TIMER3 // T3 is not connected #define COUNTER_USE_TIMER1 // T1 is not connected In FreqCount FreqCount Library, for Measuring Frequencies in the 1 kHz to 5 MHz Range // Arduino Mega #define OUTPUT_COMPARE_C_PIN 44 // unusable PWM #define OUTPUT_COMPARE_B_PIN 45 // unusable PWM #define OUTPUT_COMPARE_A_PIN 46 // transmit #define OUTPUT_COMPARE_C_PIN 8 // unusable PWM #define OUTPUT_COMPARE_B_PIN 7 // unusable PWM #define OUTPUT_COMPARE_A_PIN 6 // transmit #define INPUT_CAPTURE_PIN 49 // receive

Of course, it's impossible since those pins don't have numbers assigned and can't be accessed, at least not without extremely difficult soldering.įor example, in AltSoftSerial AltSoftSerial Library, for an extra serial port // Arduino Mega Occasionally I get emails from people asking if I can add lines for the other on-chip timers. But if anyone looks in the header, I have commented out the other possible timers.

Usually I just use #define in a header, and in the web-based documentation I only document the default setting. I've hit similar issues with a couple libraries I've published. But, if it's only going to be usable on a narrow set of Ardunio variants, why bother. My goal was to write a library that might be useful to others.
