How to delay in Arduino?In Arduino, “delay” usually means one of two things: 1) Simple blocking delay: delay() / delayMicroseconds() Milliseconds delay(1000); // waits 1000 ms = 1 second Microseconds delayMicroseconds(200); // waits 200 µs Notes delay() blocks: nothin...Jan 14 · 1 min readampheoelectronic.hashnode.dev
How to run microcontroller program in Keil?To run a microcontroller program in Keil µVision, you usually do one of two things: Run on real hardware (flash + debug via ST-LINK/J-LINK/ULINK) Run in the simulator (only for some MCUs, with limitations) Here’s the practical workflow. A) Run o...Jan 13 · 3 min readampheoelectronic.hashnode.dev

How to evaluate and improve the resource utilization of FPGA?Evaluating (and improving) FPGA resource utilization is mostly a repeatable flow: Measure accurately (what is used, where, and why) Find the true drivers (logic vs memory vs DSP vs routing/congestion) Change architecture / RTL / tool directives wi...Jan 9 · 5 min readampheoelectronic.hashnode.dev
How to know Wi-Fi adapter driver installed in Raspberry Pi 5 or not?Here’s a reliable way to tell whether a Wi-Fi adapter has a driver installed and loaded on a Raspberry Pi 5 (works for both the built-in Wi-Fi and USB Wi-Fi dongles). You’re basically checking 4 things: device detected → driver bound → firmware loade...Jan 8 · 3 min readampheoelectronic.hashnode.dev
