Registers a function to be called when a slave device receives a transmission from a master. Parameters handler: the function to be called when the slave receives data; this should take a single int parameter (the number of bytes read from the master) and return nothing, e.g.:void myHandl...
你并不需要在调用analogWriteO之前为设置输入引脚而调用pin Mode () oThe analogWrite function has nothing whatsoever 33、 to do with the analog pins or the analogRead function.这个analogWrite方法与模拟引脚或者analogRead方法毫不相干SyntaxSyntax语法 analogWrite(pin, value)ParametersParameters 参数pin: the pin...

Does not constrain values to within the range, because out-of-range values are sometimes intended and useful. The constrain() function may be used either before or after this function, if limits to the ranges are desired. 不会把值强制限制在范围之内,因为超范围的值经常也是有用的。如果需要的范...

Since 0.6.0 the weight is defined as float which allows easier calibration in other units e.g. define the weight as 2.5 kg instead of 2500 gram. The functionGetUnits()will then return its value in kg too. Also by using a float the range of calibration weights is substantially increased....
TIP: The SI4735 Arduino Library has a function to format numeric values like frequency, bfo, rssi etc. See convertToChar documentationExample:. . . void showFrequency() { char freqDisplay[10]; if (band[bandIdx].bandType == FM_BAND_TYPE) { rx.convertToChar(currentFrequency, freqDisplay,...
