bintobcd
A binary to BCD (binary-coded-decimals) encoder. Converts it’s input binary number into any number of BCD digits. First the input binary number is converted into a decimal number, then each digit is represented by 4 bits and sent to the chips outputs.
Example: To convert a 6 bit binary number into 2 digits build a bintobcd chip with 6 inputs and 8 outputs. The 1st 4 outputs will output the least significant digit (the 1s) and the other 4 outputs will output the most significant digit (the 10s). If the chip receives 100110 (38) it will output 0011 1000 - 2 digits, binary 3 and binary 8.
The bintobcd chip is very useful for sending numbers into a decimal display such as a 7 segment digit display. Each 4-bit digit output can be directly connected to a segdriver chip to display a multiple digit number.
I/O setup
- At least 1 input pin.
- Any multiple of 4 output pins.
