## HOW TO
- 1
get a PICO W board with WIFI 6$ and HEADERS ( if you not want to solder 7$ )
[PICO W board](https://www.raspberrypi.com/products/raspberry-pi-pico/?variant=raspberry-pi-pico-wh)
- 2
connect it with a USB cable ( USB A to Micro-USB-B cable ) to a PC USB port
and see drive content INDEX.HTM, INFO_UF2.TXT ( with bootloader info )
later you will need to press the [BOOT-SEL] button while connecting to see that drive again
- 3
open 2 file explorer windows and copy like drag / drop
-a- flash_nuke.uf2 ( required only if you change CPxxx version )
-b- adafruit-circuitpython-raspberry_pi_pico_w-< LANGUAGE >< DATE >< VERSION >.uf2 to it
after copy the drive will close and after 5sec drive show up again: 'CIRCUITPY'
pls find there boot_out.txt and check
- 4
you could start now edit 'code.py' with MU-Editor, but here we
delete the empty code.py and settings.toml
and copy / drag our new files and /lib/
- 5
open [MU-Editor](https://codewith.mu/) ( mode circuitpython )( should auto find that drive and open code.py )
activate the serial TAB aka REPL console ( use [CTRL][c] for stop / [CTRL][d] for reboot )
now develop code directly on the board
BUT: can not edit settings.toml on the board! ( reboot failure might happen )
that file only edit on the PC ( like with notepad )( like add your wifi login SSID PASSWORD )
and copy it to the board
- 6
good project code backup / upload to your PC
keep zips for each version
- 7
[System files download](https://circuitpython.org/board/raspberry_pi_pico_w/)
might want to check if there is a update on the core files,
download CPxxx.uf2 and adafruit-circuitpython-bundle_lib.zip
- 7a- backup all your code
- 7b- nuke the board
- 7c- flash the board with the new CPxxx.uf2
- 7d- copy back your code ( not the /lib/ )
- 7e- with the new lib.zip
copy / unzip from it new versions of the same libs used in that project
( here /adafruit_httpserver/ )
- 7f- expect to now find code errors old code .vs. new libs
and find new lib doc online to fix
- 8
after first edit settings.toml for SSID & SSID password and wanted FIX IP
open any browser ( inside your LAN ) http://192.168.1.215 and test operation
( OUT & SP number or mouse input and [ENTER] as submit )
( see also MU-REPL for diagnostic prints "www ...." )
- 9
after website operation checked and coding work finished ( incl backup )
you can disconnect the USB cable from PC and use a USB charger to power the board
( place anywhere inside your LANs WIFI area)
- 10
hardware: PID needs a
*input for PV: connect a SENSOR on ADC0
but you could also use 'linked' sensor boards..
*output from OUT: here use a LED to see the 'dimmed' control output
later can connect like a SERVO ... for real process control
