RF, IF, basebandRF signal refers to the unmodulated carrier signal; IF signal refers to the lower IF signal after heterodyne transformation of RF signal. The purpose of using IF is to facilitate ampli...
[i=s] This post was last edited by brain enthusiast on 2016-3-13 18:29 [/i] Could any expert help me see why the program inside the if statement takes up more than 100 bytes? It seems a bit abnormal. ...
I used the HELLO program in the example, but after downloading the program, I still ran the original program. I don't know what went wrong. I used MDK324 and didn't use the software in the installatio...
My experiment shows that no matter what the ECC page size is set to, the generated ECC is the same. Moreover, when the page size is 256, the ECC should be 22 bits, and the unused bits should be 0, but...
Last week, Espressif announced the launch of the low-power, low-cost ESP32-C2 chip, which is smaller in size and more powerful than the ESP8266. On the basis of meeting the needs of simple IoT applica...
