HSE: Kev kub ceev sab nraud

Feature:

Nano muaj cov yam ntxwv hauv qab no:

• STM32F303CCT6 micro maub los nta 32-ntsis Arm Cortex-M4 nrog FPU core (72 MHz max), 256-Kbyte Flash nco, thiab 48-Byte DRAM hauv pob LQFP48.
• Peb lub laub khawm:
  • SW1(rov pib dua), SW 2 (tus neeg siv khawm), SW(boot).
• Plaub LEDs:
  • D1 (liab) rau 3.3 V fais fab tuag / tawm.
  • Peb tus neeg siv LED, D2 (xiav), D3 (ntsuab), D4 (liab).
• Board connectors:
  • J1 SWB.
  • J2 USB-B Micro.
  • 2.54 hli pitch extension header rau 30 pins ntawm LQFP48 I/Os rau kev sib txuas ceev rau prototyping board thiab yooj yim soj ntsuam.
• Kev xaiv hluav taws xob: ST-LINK lossis USB VBUS.

Kho vajtse thiab layout

Lub Nano yog tsim nyob ib ncig ntawm STM32F303CCT6 micro maub los hauv 48-pin LQFP pob.
Daim duab 2 thiab Daim duab 3 pab cov neeg siv nrhiav STM32F303CCT6 thiab nws cov khoom siv (MPU6050, laub khawm, LEDs).

Kev siv hluav taws xob thiab kev xaiv lub zog

• Lub hwj chim mov yog muab los ntawm tus tswv PC los ntawm USB cable los yog ntawm SWD chaw nres nkoj siv ST-Link kev twb kev txuas.
  • U2 tswj 5V cov tswv yim los ntawm USB kom muab cov zis 3.3V ruaj khov.

Nco tseg: Tsis txhob txuas cov khoom siv hluav taws xob sab nraud rau lub qhov (socket) header.

LEDs

• D1 PWR: liab LED qhia tias lub rooj tsavxwm yog powered.
• Tus neeg siv D2: xiav LED yog tus neeg siv LED txuas nrog I / O PA1 ntawm STM32F303CCT6.
• Tus neeg siv D3: ntsuab LED yog tus neeg siv LED txuas nrog I / O PA2 ntawm STM32F303CCT6.
• Tus neeg siv D4: liab LED yog tus neeg siv LED txuas nrog I / O PA3 ntawm STM32F303CCT6.

Laub khawm

• SW1 RESET: Push khawm txuas nrog NRST yog siv los RESET STM32F303CCT6.
• SWB 2 USER: Tus neeg siv khawm txuas nrog I / O PA0 ntawm STM32F303CCT6.
• SWB 3 BOOT0: Push khawm txuas nrog BOOT0 yog siv los hloov lub khau raj hom ntawm STM32F303CCT6.
  

  NKAUS	Hom khau raj

  1	System nco

  Table 1: Boot hom

Nco tseg: Los ntawm lub neej ntawd, micro maub los khiav daim ntawv thov code los ntawm lub ntsiab flash nco. Txhawm rau hloov tus cwj pwm no, siv BOOT0 khawm.

1. Nias lub pob BOOT0 thiab tom qab ntawd nias lub pob pib dua.
2. Qhov kev txiav txim no ua rau micro maub los khiav lub khau raj ua haujlwm los ntawm lub cim xeeb ntawm lub system (piv txwv li, micro maub los nkag rau hauv khau raj loader hom).

Axis (Gyro + Accelerator) MEMS Motion Tracking

• MPU6050 sensor yog lub zog qis, tus nqi qis, thiab kev ua haujlwm siab 6-axis (Gyro + Accelerator).
• Cov khoom siv MPU6050 muab 3-axis gyroscope thiab 3-axis accelerometer ntawm tib silicon tuag, ua ke nrog onboard Digital Motion Processor (DMP), uas ua cov txheej txheem 6-axis Motion Fusion algorithms.
• STM32F303CCT6 micro maub los tswj cov sensor no los ntawm I2C interface.

OSC Clock

• LSE: OSC 32.768 kHz moos mov
  Xa mus rau sab nraud oscillator khiav ntawm 32.768 kHz. Nws feem ntau muab lub sijhawm tsawg zaus rau lub sijhawm moos (RTC) lossis lwm lub sijhawm ua haujlwm.

  PC15	OSC32_OUT

• HSE: OSC 8 MHz moos mov
  Xa mus rau sab nraud oscillator khiav ntawm 8MHz. Nws muab lub moos zaus ntau dua qhov tsim nyog rau kev tsav lub hauv paus ua haujlwm lossis lwm yam khoom siv hluav taws xob ceev.

  PF 1	OSC_OUT

USB rau UART choj

• USB rau UART choj txhawb kev sib txuas lus ntawm lub khoos phis tawj thiab STM32F303CCT6, nrog Stuart thiab UART1Rx ua tus xa thiab txais tus pins, feem, txuas nrog pins PA9 thiab PA10 ntawm micro maub los.
