I got a CC2541 a few days ago. After some tinkering, I was able to send commands to CC2541 using my mobile phone. Now I have two questions: 1. The commands I send are all single-byte. How can I send m...
Use these design techniques and ISE functional analysis tools to control power consumption. New generations of FPGAs are getting faster, denser, and have more logic resources. So how can you ensure th...
We all know how to use diodes to make switches, however, we can only turn them on and off, not control the flow of a signal over time. Furthermore, the diode's ability to act as a switch depends on th...
