In order to solve the problem that the playSound function is slow in loading large files and does not support MP3 playback, I wrote a function that simulates PlaySound to play audio files. I used conv...
Who has a blank PCB board of FPGAEP2C5T144C8N? Originally, chenzhufly gave me a blank PCB board of EP2C5Q208. I was very touched. Here, I would like to say thank you to Brother Chen! I also bought a 2...
ESP32 has good performance, with a main frequency of 240MHz, SRAM 520KB, Flash 16Mb, Bluetooth and Wifi. But how fast is ESP32? I did a test to compare ESP32, ESP8266 and PYBV10, calculated pi on them...
