Micropython
Basics
- Installing:
sudo pip install esptool esptool.py --port /dev/ttyUSB0 erase_flash esptool.py --port /dev/ttyUSB0 --baud 460800 write_flash --flash_size=detect 0 ~/Desktop/esp8266-20171101-v1.9.3.bin
- Connecting via Terminal:
sudo apt install picocom picocom /dev/ttyUSB0 -b115200
- Connecting via REPL(web):
import webrepl_setup
If you disabled automatic start-up on boot, you may run configured daemon on demand using:
import webrepl webrepl.start()
- Checking filesystem:
import os os.listdir()
- Create directories:
os.mkdir('dir')
- Remove entries:
os.remove('data.txt')
- Checking Machine Frequency & Overclocking:
import machine machine.freq() # get the current frequency of the CPU machine.freq(160000000) # set the CPU frequency to 160 MHz
- Check AP Name:
import network; ap = network.WLAN(network.AP_IF); print(ap.config('essid'));
- Change AP name and password:
import network; ap = network.WLAN(network.AP_IF); ap.active(True); ap.config(essid='MyESP8266', authmode=network.AUTH_WPA_WPA2_PSK, password='mypassword'); print(ap.config('essid'));
Projects
- Playing with GPIO:
import machine
import time
import urandom
pin = machine.Pin(2, machine.Pin.OUT)
def toggle(p):
p.value(not p.value())
while True:
time.sleep_ms(urandom.getrandbits(8))
toggle(pin)
