2024 Muallif: John Day | [email protected]. Oxirgi o'zgartirilgan: 2024-01-30 13:28

Bu virtual terminal yordamida ketma-ket aloqa uchun ARM Cortex-M4 (Texas Instruments EK-TM4C123GXL) dan foydalanadigan dastur. Chiqish 16x2 LCD displeyda olinishi mumkin va ketma -ket aloqa uchun kirish Energia IDE, Tera Team, Keil uVision yoki boshqa virtual terminal dasturlarining ketma -ket monitorida bo'lishi mumkin.

Ish paytida EK-TM4C123GXL RED LED mikrokontroller holatini ko'rsatadi. Seriya ma'lumotlarini mikrokontrollerga uzatishda EK-TM4C123GXL RED LED oq rangga aylandi. Butun elektron +5V (VBUS) va +3.3V EK-TM4C123GXL bilan quvvatlanadi. c99 kodining.bin fayli ushbu qo'llanma bilan biriktirilgan..bin faylini LM Flash Programmer yordamida mikrokontrollerga yuklash mumkin.

1 -qadam: talablar

Loyihani amalga oshirish uchun quyidagilar zarur: 1- Texas Instruments EK-TM4C123GXL

2- Potansiyometr (masalan, 5K)

3- LCD 16x2

4- Virtual terminal (kompyuterda dasturiy ta'minot)

5- LM Flash dasturchisi (kompyuterda dasturiy ta'minot)

=> Agar siz LM Flash Programmer dasturidan qanday foydalanishni va o'rnatishni bilmasangiz, iltimos, oldingi ko'rsatmalarni ko'rib chiqing yoki quyidagi havolalarni bosing:

LM Flash dasturchi yuklab olish

LM Flash Programmer yordamida.bin yoki.hex faylini yuklang

2-qadam: simlarni ulash va ulash

ARM Cortex-M4 (Texas Instruments EK-TM4C123GXL) va boshqa periferiya qurilmalarini ulash va ulash ushbu qadam bilan biriktirilgan va ularga quyidagilar berilgan:

================= TM4C123GXL => LCD

=================

VBUS => VDD yoki VCC

GND => VSS

PB4 = RS

GND => RW

PE5 => E.

PE4 => D4

PB1 => D5

PB0 => D6

PB5 => D7

+3.3V => A.

GND => K.

========================

TM4C123GXL => Potansiyometr

========================

VBUS => 1 -pin

GND => 3 -pin

=================

Potansiyometr => LCD

=================

2 -pin => Vo

=> Potansiometr yordamida kontrastni o'rnatishingiz mumkin

3 -qadam:.bin faylini yuklang

Bu qadam bilan biriktirilgan.bin faylini LM Flash Programmer yordamida ARM Cortex-M4 (Texas Instruments EK-TM4C123GXL) ga yuklang.

4 -qadam: Ma'lumotlaringizni kiritish uchun kiriting

. Bin faylini ARM Cortex-M4 (Texas Instruments EK-TM4C123GXL) ga yuklaganingizdan so'ng, siz 16x2 o'lchamli LCD displeyga chiqishingiz va terminalga kerakli kirishni kiritishingiz mumkin. Energia IDE Serial Monitor, Tera Team Virtual Terminal, Keil uVision yoki boshqa virtual terminal.
