Ngosipụta LED nsogbu na ngwọta nkịtị

Ngosipụta LED bụ otu n'ime ngwaahịa eletrọnịkị kacha ewu ewu, mana n'agbanyeghị ngwaahịa a na-eji, a ga-enwe ọdịda dị iche iche. Gịnị ma ọ bụrụ na ọ dị oké ọnụ ịgwa mmadụ ka ọ rụzie ya? Anyị na-ebe a iwebata ụfọdụ nkịtị nsogbu na ngwọta.

Otu, ihuenyo niile anaghị enwu (black screen).
1. Lelee ma a na-enye ọkụ eletrik.
2. Lelee ma ejikọrọ eriri mgbama na eriri USB ma jikọọ ya na ezighi ezi.
3. Lelee ma ọkụ ndụ ndụ dị n'etiti kaadị izipu na kaadị nnata na-egbu maramara.
4. Ma ihe ngosi kọmputa na-echebe, ma ọ bụ ebe ngosi kọmputa bụ oji ma ọ bụ na-acha anụnụ anụnụ.

Abụọ, dum LED modul adịghị enwu gbaa.
1. The kehoraizin ntụziaka nke ọtụtụ LED modul na-adịghị na-egbuke egbuke, lelee ma USB njikọ n'etiti nkịtị LED modul na abnormal LED modul jikọọ, ma ọ bụ na mgbawa 245 bụ nkịtị.
2. The vetikal ntụziaka nke ọtụtụ LED modul adịghị enwu, lelee ma ike ọkọnọ nke a kọlụm bụ nkịtị.

Atọ, n'elu ọtụtụ ahịrị nke modul LED adịghị egbuke egbuke
1. Lelee ma ọ bụrụ na ejiri eriri ahịrị jikọọ na ntinye mmepụta 4953.
2. Lelee ma 138 ọ bụ nkịtị.
3. Lelee ma 4953 ọ dị ọkụ ma ọ bụ ọkụ.
4. Lelee ma 4953 nwere ọkwa dị elu.
5. Lelee ma ejiri njikwa njikwa 138 na 4953 jikọọ.

Anọ, modul LED enweghị agba
Lelee ma data 245RG nwere mmepụta.
　

Ise, ọkara elu ma ọ bụ ala ọkara akụkụ nke modul LED adịghị enwu gbaa ma ọ bụ gosipụta nke ọma.
1. Ma enwere akara ngosi OE na ụkwụ nke ise nke 138.
2. Ma akara nke 11th na 12th ụkwụ nke 74HC595 bụ ihe nkịtị; (SCLK, RCK).
3. Ma mgbaàmà OE ejikọrọ bụ ihe nkịtị; (oghe oghe ma ọ bụ sekit dị mkpirikpi).
4. Ma akara SCLK na RCK nke ntụtụ abụọ-ahiri ejikọrọ na 245 bụ ihe nkịtị; (oghe oghe ma ọ bụ sekit dị mkpirikpi).

Ngwọta:
1. Jikọọ mgbaàmà OE na
2. Jikọọ akara ngosi SCLK na RCK nke ọma
3. Jikọọ sekit mepere emepe ma kwụpụ obere sekit
4. Jikọọ sekit mepere emepe ma kwụpụ obere sekit

Isii, ahịrị na modul LED ma ọ bụ ahịrị modul kwekọrọ ekwekọghị na-enwu ma ọ bụ gosipụta nke ọma.
1. Lelee ma a na-eresị ma ọ bụ na-efunahụ pin mgbama ahịrị nke modul kwekọrọ.
2. Lelee ma eriri akara akara na 4953 akwụsịla ma ọ bụ jiri akara ndị ọzọ kesaa ya mkpụmkpụ.
3. Lelee ma resistors elu na ala nke akara akara anaghị ere ya ma ọ bụ na-efunahụ ya.
4. Ma akara ngosi akara site na 74HC138 na 4953 kwekọrọ na-akwụsị ma ọ bụ jiri akara ndị ọzọ mee ka ọ dị mkpụmkpụ.

Ngwọta maka ọdịda:
1. Solder nke na-efu na efu ịgbado ọkụ
2. Jikọọ sekit mepere emepe ma kwụpụ obere sekit
3. Mejue ihe ndị a na-ereghị ere ma were nke na-efu.
