![]() ![]() This allows you to continuously read the COUNT register without having to synchronize each time, (it does it automatically). While (TC3->) // Wait for (read) synchronization TC_READREQ_ADDR(0x10) // Offset of the 8 bit COUNT register ![]() (I'm using the timer in 8-bit mode): REG_TC3_READREQ = TC_READREQ_RCONT | // Enable a continuous read request I read the COUNT register for TC3, but as I don't need to write to the it, I'm setting the RCONT bit in the Read Request (READREQ) register to enable continuous synchronization. In my firmware for my current project, I'm using GCLK4 as the source for all 6 timers. Serial.You should be able to feed a single GCLK to any of the TCC or TC timers. * Frequency & Period Measurement for Audio Void attach(int pin1, int pin2, int pin3) įreqPeriod\: In function FreqPeriod::begin()': C:\Users\SM\Documents\Arduino\libraries\FreqPeriod/FreqPeriod.cpp:100: multiple definition of FreqPeriod::begin()'į:C:\Program Files (x86)\Arduino/FreqPeriod.ino:51: first defined hereįreqPeriod\: In function FreqPeriod::getPeriod()': C:\Users\SM\Documents\Arduino\libraries\FreqPeriod/FreqPeriod.cpp:104: multiple definition of FreqPeriod::getPeriod()'į:C:\Program Files (x86)\Arduino/FreqPeriod.ino:55: first defined hereįreqPeriod\:C:\Users\SM\Documents\Arduino\libraries\FreqPeriod/FreqPeriod.cpp:100: multiple definition of FreqPeriod::f_capt' :C:\Program Files (x86)\Arduino/FreqPeriod.ino:51: first defined here FreqPeriod\:C:\Users\SM\Documents\Arduino\libraries\FreqPeriod/FreqPeriod.cpp:100: multiple definition of FreqPeriod::captd'įreqPeriod\: In function _vector_20': C:\Users\SM\Documents\Arduino\libraries\FreqPeriod/FreqPeriod.cpp:114: multiple definition of _vector_20'į:C:\Program Files (x86)\Arduino/FreqPeriod.ino:65: first defined hereįreqPeriod\:C:\Users\SM\Documents\Arduino\libraries\FreqPeriod/FreqPeriod.cpp:100: multiple definition of FreqPeriod::ocnt' :C:\Program Files (x86)\Arduino/FreqPeriod.ino:51: first defined here FreqPeriod\: In function _vector_28':Ĭ:\Users\SM\Documents\Arduino\libraries\FreqPeriod/FreqPeriod.cpp:119: multiple definition of _vector_28' :C:\Program Files (x86)\Arduino/FreqPeriod.ino:70: first defined here FreqPeriod\:C:\Users\SM\Documents\Arduino\libraries\FreqPeriod/FreqPeriod.cpp:100: multiple definition of FreqPeriod::capta'Ĭore.a(): In function main': C:\Program Files (x86)\Arduino\hardware\arduino\cores\arduino/main.cpp:11: undefined reference to setup'Ĭ:\Program Files (x86)\Arduino\hardware\arduino\cores\arduino/main.cpp:14: undefined reference to `loop' #if defined ( AVR_ATmega168) || defined ( AVR_ATmega48) || defined ( AVR_ATmega88) || defined ( AVR_ATmega328P) || ( AVR_ATmega1280) ![]() Volatile unsigned long int FreqPeriod::captd ![]() Volatile unsigned char FreqPeriod::f_capt TIMSK1 = _BV(ICIE1) // enable input capture interrupt for timer 1 TCCR1B = 0x01 // No prescaler (prescaler=1) TCNT1 = 0 // reset the counter - 16 bit counter If(bit_is_set(TCCR1B ,ICES1)=1) // If rising edge is detected Volatile uint8_t PulseCount // number of pulses received in current frame Volatile unsigned int Pulses // array holding number of ticks for a square shape signal, length between a rising edge to its next rising edge). What I am expecting the code do is to measure the period of a signal (ie. Aside from this, does the code looks working to you guys ? (This is my first try of programming in Arduino) Did you select the right one from the tools > Serial Port menu" ? I compiled and uploaded the file using COM5 and it uploads the file but now that I want to see the results, it is not working. Here is my code, when I run it and press on the Serial Monitor, I get an error saying "Serial 'COM5' not found. ![]()
