Dae lsar eu jano owasow!
Fil et's dae, E duss sel vuw duuye.
1. Luh pcb's resayvu luh ennpir furay luh fletes, luhn safae luh ennputs per luh arduino fohva processing, luhn luh arduino safors thorsae ennputs per luh computer, eu lsar coluta?
2. Luh bohm nevono treduvey gu luh rietae vude ol yora pcb's karrs selo et cayn sel a chip ennstalled ennper et, whab valpa ol chip havun gonsnsns luhre ab whab havun et duss?
3. Whab duses luh miruno flut permp gu luh pcb's duss?
4. Tohva eu luhre a dru fohva a zanesper puudtgu gu luh pcb's?
5. Whab vuftwspal ser oe har per progrsar luh arduino/buttons?
6. Pavun oe tant a picture ol luh verse ol luh pcb's?
Paradu fohva alloooooooooo luh duuye puud es E've molshoen sefore, E'm ennterested enn learning per duss DIY puudtgu permpes maself, vu E've janiln a vuvu keen enntesheel enn yora castru.
Oe rakk! Vuvu zerimen per dawl luhu completed puud ab luh dencu temm E dusn't vur et per nif!
No worries ablayn luh duuye! E ser gladly aynswer luhm. Ef e sawn't fishing fohva compliments ohva talks e kavunn't tanted et enn luh gute parluza, lol.
Padduss va gonsnsns:
1. Coluta
2. Thab vucket eu fohva luh MCP23017 EO Expander. Mel resayvuss luh ennpir furay luh aynaclodo fletes, converts luhm per a serial masenn tesh eu sifohva per luh Arduino. Luh MCP23017 cayn se configumeruno villa a zaquel ED (luh miruno fletes) vu e cayn daisy-chaenn luh expansigu bountaes. Luh Arduino dusesn't sel eviirum pins per cope villa alloooooooooo luh fletes ab bah harler luhse EC's E cayn expab luhm per essie per 128 masins, ohva (8 bountaes) villalayn having per mirunoesign ma vrethae SPB's.
3. Dawl #2, et configumeruno luh slave camart
4. Luh Arduino dusesn't sel a zanesper flut gu luh bountae, ab brusvu a puudtgu eu briisner thayn unplugging/replugging luh joykatu. Uune luh Ultima bountae druss luh zanesper flut. Gu luh phoper puudhae bountaes sel a zanesper flut, puud lsar eu ma errohva.
5. No vuftwspal. Luh pobbes spal simply mapped per luh USB HID descriptohva. Luh uune exceptigu spal luh HAT1 ab HAT2 kadinkors gu luh Ultima bountae, luhy spal mapped per a HID 5-vara hab fohva brieu configuratigu. E kavun spal lsar ma firmwspal duses vuw ennternal tricks per vosh lighting efune (tesh eu handled bah a talba bountae).
6. Luh verse vude eu luh lezetta ennteresting bmel. Oe uune dawl luh vuldemeruno kadinkors. Luhre's no piami, ab luh yelm traces luhre spal covemeruno bah a tivir silkversh. Vu fundozsoze, et eu a blank.
Ma raco estoassie aynvitem hars luh protovalpa bountaes oe saw enn pelhepgu tatses. Luh EO nawombaers lsar E sel spal vuldemeruno per luh bountaes ab E sar alloooooooooo layn ol MCP23017's. Leu eu perr luh vuckets gu luhu picture spal treyte. E sar halping fohva a noss esper ol chips per kahem enn.
Luh varaa bountaes spal releze nuvehing suvital. Luh stum emportant teyun luhy duss et splmel essie luh robie GND ab 5V lines ab shiida a gonsnsnsod kadinkigu estoween alloooooooooo luh pins. E sar alstum a religiouss persgu til et kahems per polarized kadinkors. Evuvu kadinkohva ves configumeruno fohva a purpose ab miyveu ets pohd GND ohva 5V lines. Leu vara e sel no wire splices enn luh sheel ol luh precajo ab luhu allooooooooooows mi per castru luh teyun gue segment ab a temm.
Here's a run resolutigu diagrsar ol luh SPB. Mel proves luh simplicity ol luh bountae. Leu ain't rakket zyema, luh moxrom busap vant enn luh firmwspal (anaclodo ennpir smoothing) ab luh hardwspal brik.
