Note: Physical Arduino Uno/Nano pin 3 has INT1, and physical Arduino pin 2 has INT0.Why do you need two functions to setup an external interrupt?In Arduino code we are all used to specifying a pin to which to apply a selected operation for example:...
The Arduino compiler is writing the low byte first followed by the high byte. In practice the code became unreliable when changing the compare value using the code above. The correct way to control the compiler is to be explicit:// 16-bit write must do H then L. noInterrupts(); OCR1AH...
I want stable code for use interrupt to read RF433/315Mhz module in loop by ESP-12F as same as Arduino code.Thanks Code: Select all#include <RCSwitch.h> RCSwitch mySwitch = RCSwitch(); void setup() { Serial.begin(9600); mySwitch.enableReceive(0...
If I use the Arduino IDE, at what priority should the task run? And is there any possibility to make it asynchronous? If I look at esp32-hal-i2c.c I see that: Code: Select all i2cWrite(num, txAddress, txBuffer, txLength, _timeOutMillis); and Code: Select all i2cRead(num, ...
Repository files navigation README MIT license OpticInterrupt Arduino library for NTE3100 Photon Coupled Interrupter Module One should download the release and install it with Arduino Note to everyone: don't use underscored in filenames because Arduino won't see those filesAbout...
The library is coded to get maximum speed and minimum code size. The LowLevel example without the API takes 4uS to enter the interrupt function in the worst case which is pretty good and might be even better than the PinInterrupt code from the official Arduino core due to high optimization...
specifically, the hardware would take the form of an Arduino Mega 2560 with a USB Host Shield. There was plenty of code and examples that showed how you could read the mouse position and clicks from the Arduino, but [rehsd] still had to figure out a way to get that information into th...
OK, so who handles the Arduino ESP stuff? I looked at xtensa_vectors.S code and see how the interrupt handler works... and I can see why it takes 220ns before the high level interrupt routine is called. Can you tell me how I can determine WHERE (memory address) the interrupt table ...
