O lenei vaega o loʻo faʻamatalaina se auala e faʻaalia ai le faʻaogaina o le Drone controller. O le mamanu fa'asino e mana'omia ai ni nai fa'aoga fa'aopoopo i fafo o le laupapa ma se afi.
- O se 5V eletise sapalai i le PWM pule
- O le PWM pule na fa'aaogaina e tu'uina atu ai se fa'amatalaga saosaoa po'o se potentiometer e tu'uina atu ai se vol eseesetagu fa'amatalaga saoasaoa
- O se afi BLDC ma faʻamaufaʻailoga e pei ona faʻamatalaina i le Faʻaopoopoga B
- O se puna mana maa o le 11-14V ma le 1500mAH gafatia
So'o se mea fa'atusa po'o se fa'ata'ita'iga e mafai ona fa'aoga e sui ai mea o lo'o fa'aalia iinei mo le fa'agaioiga manuia. O lo'o fa'aalia i lalo e exampo mea fa'aoga o lo'o i luga ma afi na fa'aaogaina mo lenei fa'ata'ita'iga.

Fa'aaliga: AUA LE FA'API'I LE TAIMI I LE TAIMI LENEI
Laasaga 1: So'oga autu puna mana
Fa'afeso'ota'i le maa '+' ma le '-' i le VDC ma le GND e fa'aola ai le pule atamai. E mafai fo'i ona fa'aoga se eletise DC.
Laasaga 2: Faʻailoga faʻamatalaga vave i le pule Drone atamai.
E ave e le pule le fa'asinomaga fa'aoga saosaoa mai le pule PWM ile 5V maualuga maualuga. O le gaioiga a le PWM pule e maua ai se fa'ailoga 5V e fa'asino i le eleele e feso'ota'i i se pine fa'ataga fa'apalepale 5V e pei ona fa'aalia i le ata. O loʻo faʻaalia foi le nofoaga mo le fesoʻotaʻiga eleele.
Laasaga 3: Sapalai eletise i le PWM pule.
Fa'afeso'ota'i le Suiga fa'aulu masani i fa'amau maa ma le mea e maua (5V) i le sapalai o le PWM.
Laasaga 4: PWM fa'atonu fa'atonu:
O le lautele o le pulupulu faailo mai le PWM e fa'amaonia mo se fa'ailo aoga i le firmware e puipuia ai le liliu sese ma le so'ona saoasaoa. O le pule e lua ki fa'amau. Filifili le faiga tusi lesona e faʻaaoga ai le ki "Filifili". Fa'aaoga le "Pulse Width" fa'amau e filifili ai i le va o le 3 tulaga o le fa'atonutonuina o le saoasaoa. O le ki o lo'o fa'ata'amilo i laina e 3 mo galuega fa'asologa o tiute PWM i lomitusi ta'itasi.
- Va'aiga 1: 4-11%
- Va'aiga 2: 10-27.5%
- Va'aiga 3: 20-55%
O le fa'aaliga fa'aaliga e ese mai le 800 i le 2200 mo se suiga laina i le taamilosaga tiute i totonu o le laina. O le liliuina o le potentiometer i luga o le PWM pule o le a faʻateleina pe faʻaitiitia ai le gaosiga o le PWM.
Laasaga 5: So'oga fa'amau afi:
Faʻafesoʻotaʻi faʻamau afi i le FASE A, B, ma le C. O le faʻasologa e filifili le itu o le taamilosaga o le afi. O le suiga mana'omia o le Drone o lo'o va'ava'ai fa'asaga i totonu o le afi e taofia ai le fa'amalo o le pe'a. O le mea lea e taua ai le faʻamaonia o le taamilosaga aʻo leʻi faʻapipiʻiina lau. Tuuina atu se faailoilo faasino PWM e ala i le tweaking o le potentiometer i luga o le PWM pulea e amata i le tulaga laititi o le pulupulu lautele (800). O le a amata ona taamilo le afi ile 7.87% o le taamilosaga tiute (50Hz) ma luga. O le fa'aaliga 7-Segment o lo'o fa'aalia ai le 1573 (7.87% o le taamilosaga o tiute) i le 1931 (10.8% o le taamilosaga tiute) pe a taamilo le afi. Fa'amautu le itu o le taamilosaga o lo'o fa'afeagai i le itu. Afai e le fesuia'i so'o se lua feso'ota'iga i fa'amauga afi. Fa'afo'i le potentiometer i le tulaga aupito maualalo le saoasaoa.
Laasaga 6: Fa'apipi'i le Fa'aola:
Aveese le malosi o le maa. Fa'amau le lau pe'ape'a e ala i le viliina i totonu o le afi afi i le fa'asaga i le uati. Uu mau le laau/motor ma faaloaloa le lima ma i se mamao saogalemu mai fa'alavelave uma ma tagata a'o galue. Fa'afeso'ota'i le eletise. O le gaioiga o le pe'a o le a fa'amalosi i le lima pe a taamilo, o lea e mana'omia ai le pipii mau e puipuia ai manu'a o le tino. Tweak le potentiometer e sui ai le saoasaoa (fa'aaliga fa'aalia i le va o le 1573 ma le 1931) E fa'auma ai le fa'ata'ita'iga.
O le ata o loʻo i lalo o loʻo faʻaalia ai le seti uma o uaea mo le faʻataʻitaʻiga.
