Rather than using a full Raspberry Pi model, this project is built around Pimoroni's Tiny 2040 board. Sharing the same RP2040 SoC as the Raspberry Pi Pico but in a smaller form factor, it's better sui...
Some engineers may not pay much attention to map files (memory mapped files) in daily project development, but once you understand the map file, you will get twice the result with half the effort in t...
The black part of the data is what I want to send. The ZigBee module I sent is the ZigBee module that I burned into the IAR project, and the receiving ZigBee module is the module that the manufacturer...
This is the circuit diagram of TL431 outputting 2.5V, but when I used it, I measured that the output of TL431 was 2.481V with an accuracy of 1%. How should the resistor R1 in this circuit be selected?...
