STM32F103C8T6 ARM STM32 Module mafi ƙarancin tsarin haɓaka tsarin shine kwamitin haɓakawa wanda ya dogara da microcontroller STM32F103C8T6. An tsara shi don tsara shi ta amfani da Arduino IDE kuma yana dacewa da nau'ikan clones na Arduino, bambance-bambancen, da allunan ɓangare na uku kamar ESP32 da ESP8266.

Hukumar, wanda kuma aka sani da Blue Pill Board, tana aiki a mitar kusan sau 4.5 fiye da Arduino UNO. Ana iya amfani da shi don ayyuka daban-daban kuma ana iya haɗa shi da kayan aiki kamar nunin TFT.

Abubuwan da ake buƙata don gina ayyukan tare da wannan jirgi sun haɗa da STM32 Board, FTDI Programmer, Nunin TFT Launi, Maɓallin Turawa, Ƙananan Gurasa, Waya, Bankin Wuta (na zaɓi don yanayin tsayawa kadai), da USB zuwa Serial Converter.

Tsarin tsari

Don haɗa allon STM32F1 zuwa 1.8 ST7735-tushen TFT Nuni mai launi da maɓallin turawa, bi haɗin fil-to-pin da aka kwatanta a cikin tsarin da aka bayar.

Kafa Arduino IDE don STM32

1. Bude Arduino IDE.
2. Je zuwa Kayan aiki -> Board -> Manajan Hukumar.
3. A cikin akwatin tattaunawa tare da sandar bincike, bincika "STM32F1" kuma shigar da kunshin da ya dace.
4. Jira tsarin shigarwa don kammala.
5. Bayan shigarwa, hukumar STM32 ya kamata yanzu ta kasance don zaɓi a ƙarƙashin jerin allon Arduino IDE.

Shirye-shiryen allon STM32 tare da Arduino IDE

Tun lokacin da aka kafa shi, Arduino IDE ya nuna sha'awar tallafawa kowane nau'i na dandamali, daga Arduino clones da bambancin masana'antun daban-daban zuwa allon ɓangare na uku kamar ESP32 da ESp8266. Yayin da mutane da yawa suka saba da IDE, sun fara tallafawa ƙarin allunan da ba su dogara da kwakwalwan ATMEL ba kuma don koyaswar yau za mu kalli ɗaya daga cikin irin waɗannan allon. Za mu bincika yadda ake tsara tsarin tushen STM32, hukumar haɓaka STM32F103C8T6 tare da Arduino IDE.

Hukumar STM32 da za a yi amfani da ita don wannan koyawa ba kowa ba ce face STM32F103C8T6 guntu-tushen guntu STM32F1 ci gaban kwamitin da aka fi sani da "Blue Pill" a layi tare da launin shudi na PCB. An yi amfani da Blue Pill ta hanyar STM32F32C103T8 ARM mai sarrafa 6-bit mai ƙarfi, wanda aka rufe a 72MHz. Hukumar tana aiki akan matakan dabaru na 3.3v amma an gwada filayen GPIO don zama masu jurewa 5v. Duk da yake baya zuwa da WiFi ko Bluetooth kamar bambance-bambancen ESP32 da Arduino, yana ba da 20KB na RAM da 64KB na ƙwaƙwalwar filasha wanda ya sa ya isa ga manyan ayyuka. Hakanan yana da fil 37 GPIO, 10 daga cikinsu ana iya amfani da su don firikwensin Analog tunda suna da ADC kunna, tare da wasu waɗanda aka kunna don SPI, I2C, CAN, UART, da DMA. Don hukumar da ke kusan $3, zaku yarda da ni cewa waɗannan ƙayyadaddun bayanai ne masu ban sha'awa. An nuna taƙaitaccen sigar waɗannan ƙayyadaddun bayanai idan aka kwatanta da na Arduino Uno a hoton da ke ƙasa.

Dangane da ƙayyadaddun bayanai da ke sama, mitar da Blue Pill ke aiki yana kusan sau 4.5 sama da Arduino UNO, don koyawa ta yau, azaman tsohonampA kan yadda ake amfani da allon STM32F1, za mu haɗa shi zuwa nunin TFT mai girman 1.44 inci kuma mu tsara shi don ƙididdige yawan “Pi”. Za mu lura da tsawon lokacin da hukumar ta ɗauka don samun ƙimar kuma kwatanta shi da lokacin da Arduino Uno ke ɗauka don yin aiki iri ɗaya.
