Rub lub pob hauv qab no. Muaj qhov chaws thiab suav ua cov ntaub ntawv hex.

Yog tias koj tsis xav nyeem cov lej, tsuas yog hlawv cov ntawv.hex rau hauv MCU. Siv USB rau TTL downloader thiab STC-ISP software rub tawm cov cai rau MCU. Txuas TXD, RXD thiab GND.

Rub tawm STC-ISP software ntawm no:

Yog tias lub interface ntawm STC-ISP yog Suav, koj tuaj yeem nyem lub cim sab laug sab saud kom hloov cov lus rau lus Askiv. Txog qhov teeb tsa kev teeb tsa ntawm STC-ISP thov xa mus rau cov vis dis aus hauv Kauj Ruam 1.

Cov lej tau sau rau hauv C. Siv Keil software txhawm rau kho thiab sau nws.

Koj tuaj yeem siv qhov DIY Function Generator los tso tawm Square waveform lossis Sine waveform teeb liab.

Interface:

  • Hauv qab sab laug qhia hom kev hloov pauv (Square/Sine) thiab cov xwm txheej tso tawm (ON/OFF)
  • F: Zaus
  • D: Lub luag haujlwm ntawm Square Waveform
  • CD: Clock Division Coefficient (Rau cov ntaub ntawv nkaus xwb)
  • P: PWM zaus rau kev tsim Sine Waveform (Rau cov ntaub ntawv nkaus xwb)
  • Pt: Tus naj npawb ntawm cov ntsiab lus rau kev tsim Sine Waveform (Rau cov ntaub ntawv nkaus xwb)

Kev Ua Haujlwm:

  • Nyem Nyem Encoder: Hloov Zaus thiab Ua Haujlwm hauv Square Waveform Interface
  • Ob Nyem Nyem Encoder: Pib/Nres Teeb Meem Tso Tawm
  • Ntev Xovxwm Encoder: Hloov ntawm Square Waveform/Sine Waveform/Voltage Information
  • Rotate Encoder: Kho Parameters

Kauj Ruam 6: Cov Lus Qhia

Lub teeb liab tso tawm tsis muaj peev xwm thauj khoom. Yog tias koj xav tsav lwm qhov kev tivthaiv, thov qhia rau koj tias siv lub tshuab ua haujlwm zoo los txhim kho lub peev xwm thauj khoom.

Kauj Ruam 7: Npaj Yav Tom Ntej

Txoj Kev Npaj Yav Tom Ntej

Kuv npaj yuav ua lwm Lub Chaw Tsim Khoom nrog STM32.

Cia siab rau nws

  • Muaj peev xwm tsim daim duab peb sab thiab Pom waveform ntxiv.
  • Qhov zaus ntawm Sine waveform tuaj yeem siab dua 10kHz.

Yog tias koj muaj lus qhia lossis xav tau txog txoj haujlwm no, thov ua siab zoo qhia kuv.

Vam tias koj nyiam.
