WebBasically, a byte with value 0-255 in Modbus RTU mode will in Modbus ASCII mode be sent as two characters corresponding to the hex value of that byte. For example a value of 76 (dec) = 4C (hex) is sent as the byte 0x4C in Modbus RTU mode. This byte happens to correspond to the character ‘L’ in the ASCII encoding. WebJul 20, 2009 · Basically, you use the formula: bitNSet = (originalInteger & (1 << N) == 1 << N) Effectively, every integer is represented by a binary sequence. For example, 39 would be represented by 100111. Each one and zero is a bit. To get a bit, you have to AND it, which gets all the bits which are set in both of the numbers given to it. short unwinding means

"In computing, the least significant bit (LSb) is the bit position in a binary integer representing the binary 1s place of the integer. Similarly, the most significant bit (MSb) represents the highest-order place of the binary integer. The LSb is sometimes referred to as the low-order bit or right-most bit, due to the convention in positional notation of writing less significant digits further to the r… " - To set one or more bits in a byte vaue
