Python Code for the Si514 Programmable Xtal Oscillator

I’ve put together a number of project using the Si5351. However, I’ve got to admit that with its surface mount package and need for an external crystal, it’s kind of a hassle to work with. For that reason, I purchased a few Si514 to see how they compare. The Si514 is a single frequency user-programmable …

From Binary To BCD…And Back Again (Part 2)

In the previous post I described the algorithm for converting a binary number to binary-coded-decimal (BCD). In this post I’ll describe an algorithm for doing the reverse; converting a BCD number to binary. The algorithm is based on repeated division and is best explained by example. Begin with a decimal number and divide by 2. …

From Binary To BCD…And Back Again (Part 1)

Binary coded decimal (BCD) is a way of representing numbers in a computer as decimal rather than binary digits. Most commonly 4 bits are used to represent each digit since 4 bits can contain the numbers 0-9 and it allows two digits to be packed into a single byte. For those who still enjoy assembly …
