The case statements in voidTwoWire::setClock(uint32_t freq)are at odds with Wire for Uno R3. Uno R3 allows a range of clock values. // Probably R3 should be range checked. void TwoWire::setClock(uint32_t clock) { twi_setFrequency(clock); } void twi_setFrequency(uint32_t frequency)...
Wire.setClock(100000); // 400kHz I2C clock. Comment this line if having compilation difficulties //Wire.setWireTimeout(3000, true); //Arduinio timeout value in uSec Wire.setTimeout(100); //timeout value in mSec #elif I2CDEV_IMPLEMENTATION == I2CDEV_BUILTIN_FASTWIRE Fastwire::setup(40...
my interrupt routine was counting only the RISING clock signals @ 490hz. When I ported the code to the nano, I realized that it did not have the same PWM on analog 0 as the mega did. So I kept the same interrupt
Wire.setSCL(pin) Configure the pin used for clock. Possible alternate pins are shown on the pinout card. This function may be called before or after Wire.begin(). All pins used must have real pullup resistors. Use of Other I2C Ports To use the other ports, replace Wire with Wire1,...
触发超时时,会设置一个标志,该标志可以使用getWireTimeoutFlag()查询,并且必须使用clearWireTimeoutFlag()手动清除(并且在调用setWireTimeout()时也会清除)。 请注意,此超时也可能在等待时钟延长或等待第二个主设备完成其事务时触发。因此,如果需要,请确保调整超时以适应这些情况。典型的超时时间为 25 毫秒(这是 SM...

Arduino shiftOut : How to create serial output to control chips.Send data to a chip by sending a clock and sending serial data. It is a software parallel to serial converter. Chips use a serial inputs to reduce connections. Instead of 8 or 16 pins to a chip you just use two! - a...
