why micropython?
why not micropython
but it's python
micropython • lean and efficient implementation python3 run on micro
controller ( 256k code and 16k ram ) • microcontrollers ( cpu + memory + I/O on a single board ) • pyboard • esp8266 family • esp32 • micro:bit
microcontroller • sensors, display and actucator • sometimes called Internet
of Things • cheap, long-batter-life, low-power-cpu • assembly or c programming is needed
ESP8266 based • 80Mhz CPU, 64KB RAM, 512KB to 4MB
flash • WIFI ( 802.11 b/g/n ) • 16 GPIO / SPI / I2C / I2S / UART • 3.3Volt • 2 ~ 3$ in aliexpress
Micro:bit • half-sized credit card • arm based, 16Mhz, 16KB
MEM, 256KB flash, • Bluetooth • accelerometer, magnetometer • 5X5 LED Array • three push button • web based compiler • UK/BBC Powered
from virtual to reality
how to code? • REPL on serial, wifi • RUN
CODE sniffit and TEST Code • build && flashing rom • run production(?) • upip
Demo • LED on off • button LED on off
• send line notification • get thermostat • send thermostat via line
Demo
need to know more • battery • hardware interrupts •
drivers • memory usage check..
