In C++ reading from a non-active member is undefined behavior. quick and dirty hack: treat the array as 4 unsigned integers rather than 8 bytes sot the voltage is just the third value of the 4-element array. For those who are not familiar with the shiftRight operator, Arduino has two helper functions ( highByte () and lowByte ()) for beginners or those not familiar with bit manipulation. Two of these connections simply extend the same clock and latch signal from the Arduino to the second shift register (yellow and green wires). This means that line. To refer to a particular location or element in the array, we specify the name of the array and the position number of the particular element in the array. dataRED = dataArrayRED[j]; From now on those will be refered to as the dataPin, the clockPin and the latchPin respectively. In other words, you can use it to control 8 outputs at a time while only taking up a few pins on your microcontroller. XIII, 'quibus haec sunt nomina'. Just laid off? To store an integer, we need 4 bytes of memory. You've got your parameters the wrong way round. If you don't have too many bits, you can read and write one bit at a time from the byte array into the int/long with bitRead() and bitWrite(). Nervous about possible layoffs? If you want to print an array of hexadecimal value (with two digits), you have to use sprintf function and change declaration of b array. The first byte (higher) will be stored on the current address index, and the second byte (lower) will be stored on the next following address. It sends out a second byte. Unlike the HIGH and LOW states, you can"t set pins to their high impedance state individually. It's by pulsing second pin, the clock pin, that you delineate between bits. How fast would supplies become rare in a post-electric world? You can get around this by controlling the MR and OE pins from your Arduino board too, but this way will work and leave you with more open pins. Not the answer you're looking for? Therefore you need 4 bytes in your array to store each float. An array is a consecutive group of memory locations that are of the same type.
