An excerpt from Christopher Paul’s “Parsing PWM (DAC) performance: Part 1—Mitigating errors”: “I was surprised to discover that when an output of a popular µP I’ve been using is configured to be a ...

If GPS connection with satellites 0.5Hz >> green LED lights up. GPS pulse is connected to input 74HC08 and input STM32F103C8. The square wave from AD9851 is converted to a 3.3V signal using a 1N4001 ...

AD9851 70 MHz 0..31 x 11.25° has more options. Note that at the max frequency the devices do not give a nice sine any more. You need to check what is acceptable for your project. The library has a ...

The DAC is a discrete R-2R type as at the time of development a suitable IC DAC was not available. This is driven by a bank of AND gates (three 74HC08), which are in turn driver by two 74HC393 dual ...

This model is the basis for concrete realization of the MSRG on integrated circuit. The general form giving the output of each flip flop is defined by [8] : Four 74HC08: Quad 2-Input AND Gate A ...

[Russell] sent in a neat home automation project he’s been working on. Even though the project only has two devices so far, we can already see the potential of his project. Instead of the X10 ...
