Duane's involvement in the hardware and software design world goes back to the days of the CDP1802 and Z80 up through current microcontrollers such as PIC, and ARM. After hours, he designs microcontroller and motor control boards for small robots under the moniker SteelPuppet. In his day job, he has been dishing out PCB layout and DFM advice via the Screaming Circuits blog since 2006. He is also a contributor to industry technical publications and conferences on the topics of trends in prototyping, and ways to improve efficiency in product development efforts. FPGAs are a new venture for Duane. Follow him on this site as he transitions from gate array newbie, expands his skill set and adds FPGA functionality to his robots and other projects.
Would you class these as adages, aphorisms, axioms, dictums, epigrams, maxims, precepts, saws, truisms, or... well, what?
Here we discover how to use the XADC (Xilinx Analog-to-Digital Convertor) in the Zynq All Programmable SoC to read the chip's internal temperature and voltage parameters and output them over an RS-232 link.
When extreme thermal cycling causes circuit boards and chip packages and the silicon die in the packages to expand and contract at different rates, problems may ensue.
In part 3 of this epic tale we consider how we might use tri-state buffers, leading up to the legendary bi-directional buffer.
Digital engineers are often confused among operational amplifiers, differential amplifiers, and instrumentation amplifiers; this is exacerbated by the fact that their circuit symbols can be similar.
