为了给上三年级的孩子做的寒假社会实践作业的作品,对于平衡车和寻迹车都感觉娱乐意义大于教育意义,所以想了又想,不如做一个这个RGB混色实验装置的教育意义更大,由于使用了UNO板只支持2个中断通道,所以没有使用太多的编码器,此处为硬件限制。本着开源的思想,把源码都已经进行了详细的解释备注。初学者可以参考,高手批...
Pin Change interrupts trigger on all RISING and FALLING (ie, "CHANGE") signal edges. Furthermore, the processor's pins, and pin change interrupts, are grouped into “port”s, so for example on the Arduino Uno there are three ports and therefore only 3 interrupt vectors (subroutines) availab...
int Pulses =2; //Digital Pin 2 on Uno volatile int pulsecount; //Volatile integer to store pulse count in void setup() { Serial.begin(9600); rtc.begin(); //start rtc pinMode(Pulses, INPUT); //Make Pin2 Input attachInterrupt(digitalPinToInterrupt(Pulses), CountPulses ,FALLING); //Use...

Pins 2 & 3 on the Arduino are great to attach interrupts to; to pick up input even when the Arduino is asleep. The AVR chip though provides 3 more interrupt vectors that can be used to catch interrupts on all pins – even the crystal pins. ...
the MCP4790 has 64 Bytes of SRAM storage available and features 2 separate alarms that can be set to be recurring or a single use. The alarm state can be checked using library functions or can pull down the the MFP (multi-function pin) for a hardware interrupt or other action. The MCP...
Includes a list of all interrupt vectors that can be used, how the flags are cleared (not a substitute for the datasheet - just a very quick reminder), which parts each vector exists on, and and what parts of the core, if any, make use of a vector. It also has general guidance ...
This library enables you to use Interrupt from Hardware Timers on an Arduino, such as Nano, UNO, Mega, etc. It now supports 16 ISR-based timers, while consuming only 1 hardware Timer. Timers' interval is very long (ulong millisecs). The most important feature is they're ISR-based ...
The reason for this is that the BOOTEND fuse sets the location of the interrupt vectors. If the application is started at 0x200, as it would for code compiled for use with Optiboot, but BOOTEND is set to 0, the hardware would, when an interrupt fired, jump to the blank section of ...
