There are 2 CPU cores that can be individually controlled or powered, and the clock frequency is adjustable from 80 MHz to 240 MHz
ESP32 contains two low-power Xtensa® 32-bit LX6 microprocessors. The internal memory includes: • 448 KBytes ROM for booting and core functions. • 520 KBytes on-chip SRAM for data and instruction. • 8 KBytes SRAM in RTC, which is called RTC SLOW Memory and can be accessed by the co-processor during the Deep-sleep mode. • 8 KBytes SRAM in RTC, which is called RTC FAST Memory and can be used for data storage and accessed by the main CPU during RTC Boot from the Deep-sleep mode. • 1 Kbit of EFUSE, of which 256 bits are used for the system (MAC address and chip configuration) and the remaining 768 bits are reserved for customer applications, including Flash-Encryption and Chip-ID.
데이터 시트 찾아보니 main.py를 쓰면 된다고 언급되어 있다. (최상위 디렉토리에 넣으면 안되는건가? 왜 안되지? ㅠㅠ)
If you "save a file to the device" and give it the special name main.py, then MicroPython starts running that script as soon as power is supplied to Raspberry Pi Pico in the future.
