Lenaneo la Microcontroller bakeng sa ba qalang
Lenaneo la microcontroller le fetohile tsebo e batloang haholo mehleng ea theknoloji ea sejoale-joale. Microcontroller ke yuniti e nyane ea khomphutha e kenyeletsang CPU, memori, le lisebelisoa tsa ho kenya/ho ntša tse kopantsoeng ka har'a chip e le 'ngoe. Microcontroller li sebelisoa khafetsa lisebelisoa tsa elektroniki tsa letsatsi le letsatsi tse kang lithelevishene, mechini ea ho hlatsoa, li-ontong tsa microwave, le mefuta e fapaneng ea lisebelisoa tsa indasteri. Sengoloa sena se tla akaretsa metheo ea mananeo a microcontroller bakeng sa ba qalang, ho kenyeletsoa lisebelisoa le lipuo tse tloaelehileng tsa mananeo, le mehato ea ho qala ka projeke ea hau ea pele.
Motlakase o monyenyane ke eng?
Molaodi e nyane ke khomphutha e nyane e potolohong e le 'ngoe e kopaneng (IC) e etselitsoeng ho laola lisebelisoa tsa elektroniki. Molaodi e monyenyane hangata o na le:
– Yuniti e Bohareng ea Ts'ebetso (CPU)
– Memori ea Phihlello e sa Lebelloang (RAM)
– Memori ea ho Bala Feela (ROM)
– Likou tsa I/O (Input/Output)
- Sebali sa nako
– Disebediswa tse ding tse kang ADC (Analog ho ya ho Digital Converter) le DAC (Digital ho ya ho Analog Converter)
Mehlala e meng ea li-microcontroller tse tsebahalang har'a batho ba ratang ho itlosa bolutu le litsebi ke letoto la AVR ho tsoa ho Atmel, PIC ho tsoa ho Microchip Technology, le ARM Cortex-M ho tsoa ho ARM Holdings.
Lisebelisoa le Software tse Hlokahalang
Ho qala ho etsa mananeo a li-microcontroller, o tla hloka lisebelisoa le software ea motheo:
1. Microcontroller kapa Boto ea Nts'etsopele: Mohlala, Arduino, STM32 Nucleo, kapa Raspberry Pi Pico.
2. Thapo ea USB: Hangata e sebelisoa ho hokela boto ea nts'etsopele khomphuteng.
3. Khomphutha e nang le sistimi e sebetsang ea Windows, macOS, kapa Linux.
4. Tikoloho e Kopantsweng ya Ntshetsopele (IDE): Sethala sa ho ngola, ho kenya le ho leka khoutu. Mehlala ya di-IDE tse sebediswang haholo ke Arduino IDE, MPLAB X IDE (bakeng sa PIC), le Keil uVision (bakeng sa ARM).
5. Puo ea Lenaneo: C/C++ ke puo e sebelisoang haholo bakeng sa mananeo a microcontroller, leha liboto tse ling tse kang Arduino li lumella tšebeliso ea lipuo tse bonolo tsa C++.
Ho qala ka Arduino
Arduino ke sethala se tsebahalang haholo sa taolo e nyane mme se loketse ba qalang. Arduino e na le diboto tse mmalwa, tse kang Arduino Uno, Mega, le Nano, tse sebedisang taolo e nyane ya AVR (jwalo ka ATmega328). Mehato ya motheo ya ho qala ho hlophisa taolo e nyane ka Arduino ke ena:
Ho kenya le ho seta Arduino IDE
1. Khoasolla Arduino IDE: Etela webosaete ea semmuso ea Arduino (www.arduino.cc) 'me u khoasolle mofuta oa morao-rao oa Arduino IDE o lumellanang le sistimi ea hau ea ts'ebetso.
2. Kenya Arduino IDE: Latela ditaelo tsa ho kenya Arduino IDE khomphuteng ya hao.
3. Kgokelo ya Boto ya Arduino: Sebedisa thapo ya USB ho hokela boto ya hao ya Arduino khomphuteng ya hao. Netefatsa hore bakganni ba boto ba kentswe hantle.
4. Kgetha Boto le Kou: Bula Arduino IDE, tsamaya ho `Tools` -> `Board`, mme o kgethe mofuta wa boto eo o e sebedisang (mohlala, Arduino Uno). Ka mor'a moo, kgetha `Tools` -> `Kou` mme o kgethe kou e loketseng ya serial.
Lenaneo la Pele – “Lumela Lefatše” ka LED
E 'ngoe ea merero ea pele eo ba qalang ba e etsang hangata ke ho panya LED, e tsejoang hape e le lenaneo la "Hello World" lenaneong la microcontroller.
1. Bula Arduino IDE: Bula Arduino IDE ebe o kgetha `Faele` -> `E Ncha` ho theha setshwantsho se secha.
2. Ngola Khoutu ea Lenaneo: Kenya khoutu e latelang ho panya LED e hahiloeng kahare ho phini ea 13.
"`c
void setup () {
// Beha phini ea 13 e le SEHLAHISOA
pinMode (13, TSELA);
}
sekgoqetsane se se nang letho () {
digitalWrite(13, HIGH); // Bulela LED
tieho (1000); // Emela motsotsoana o le mong
digitalWrite(13, TLAASE); // Tima LED
