Some years ago I developed a hardware solution for a young entrepreneur that was looking for a way to alert pet owners about dangerously high (or low) temperatures in the vicinity of their animals. The desire to build such a device was born out...
Last night I powered up all of my Keysight/Agilent gear(four instruments in total then started BenchVue Three of the four instruments were detected by BenchVue which up until this Road Test was normal My 53230A53230A counter though connected to...
While cleaning out a corner of my basement to prepare for some renovations I came across a box full of electronic components that I hadn't looked at in years. Each part I picked up brought back a memory of its origin. Here was an HC11 eva...
A story of embedded development on two platforms with similar goals In late 2013 I was blogging about creating a WS2811/WS2812 RGB LED controller using a PIC18F4520. My work life got fairly busy after Christmas and I dropped the ball on t...
First the progress I've developed solid PIC Basic Pro code that can reliably drive a 4m string of WS2811 RGB LEDs at 60 devices/m without spurious resets. I'm using PBPX 3.0.7.4 compiler, MPASMX assembler and a Microchip PICKIT 3 p...
SO, I blew up some stuff by not paying attention to sound design principles...It appears I've blown up the first LED device in both of my LED strings. In my rush to experiment with the strings and the PIC driver code I neglected to place a ...
This weekend I successfully developed a coding approach that allowed me to drive the LED strings discussed in previous posts with a PIC microcontroller. My work with the Agilent 33522B ARB gave me enough insight into timing and power supply loa...
In this post I provide details about the signal format used to program the WS2811 RGB LED driver. These details are needed to program appropriate pulse trains into the Agilent 33522B. I will also explain an interesting anomaly I discovere...
I'd like to share a practical application for the arbitrary waveform (ARB) function in the Agilent 33522B. First, some background on the application. I'm working to design and build a controller for RGB LED strips, like the one shown in Fi...
