19 februára, 2020 | Posted by doc. Pančík in Hlavná stránka
  • Prolog:
  • — — Student si urobia Upgrade obsahu USB kluca.
  • — — Este raz overime pocet potrebnych kitov TI LAUNCHAPD  na objednanie.
  • TEMA: Import projektov 
  • 0. Otvorit si manual ON-LINE k TI CSS :  https://software-dl.ti.com/ccs/esd/documents/users_guide/ccs_glossary.html
  • 00. Zakladny dokument podla ktoreho pojdeme vo vyucbe : c:\STUDENT\Mikroprocesorove_Systemy_LETO_2020\STUDY\200212 STUDY MSP430 from Texas Instruments\MSP_Design_Workshop.pdf
  • 000. Manual k nami pouzivanym procesorom MSP430 : c:\STUDENT\Mikroprocesorove_Systemy_LETO_2020\STUDY\200212 STUDY MSP430 from Texas Instruments\MSP430x5xx and MSP430x6xx Family User’s Guide.pdf
  • 1. Obnova rozlozenia okien v CCS (TI Code Composer Studio):
  • — Windows –> Perpective –> Reset Perspective
  • — Windows –> Perpective –> Open Perspective –> CCS edit (default)
  • 2. Priprava CSS na pracu :
    • — s podadresarom sa  c:\STUDENT\Mikroprocesorove_Systemy_LETO_2020  sa „nehybe“   bude sluzit aj pri skuske ako zdroj informacii 
    • — kazdy student ma svoj podadresar  C:\STUDNET  – tam sa kopiruju vychodzie projekty
    • — vymazanie (DELETE) vsetkych projektov v Project Explorer
    • — vytvorenie si podadresara s PRIEZVISKOM vo workspace – tam si da student svoje projekty vytvorene v CSS
    • — do workspace sa nic nekopiruje je to TOXICKE . mozu sa tam robit len poddresare s nazvom PRIEZVISKO studenta 
  • 3. Priprava suborov pre pracu :
  • — kopirovanie z c:\STUDENT\Mikroprocesorove_Systemy_LETO_2020\WORK\msp_workshop\lab_02a_ccs_solution\ do c:\STUDENT\Youth_PANCIK\lab_02a_ccs_solution\
  • — c:\STUDENT\Mikroprocesorove_Systemy_LETO_2020\WORK\msp_workshop\lab_02b_blink_solution\ do c:\STUDENT\Youth_PANCIK\lab_02b_blink_solution\
  • — c:\STUDENT\Mikroprocesorove_Systemy_LETO_2020\WORK\Mikroprocesorove systemy – cvicenia\Cv1_1_GPIO\ do c:\STUDENT\Youth_PANCIK\Cv1_1_GPIO\
  • — c:\STUDENT\Mikroprocesorove_Systemy_LETO_2020\WORK\Mikroprocesorove systemy – cvicenia\Cv2_1_GPIO\ do c:\STUDENT\Youth_PANCIK\Cv2_1_GPIO\
  • 4. Import vsetkych styroch projektov do workspace CSS a nasledne CLEAN –> BUILD –> DEBUG
  • 5. Podrobne vysvetlenie vsetkych programov, krokovanie a prezerane premennych
  • 6. Vytvorenie otazok pre skusku tak, ze vsetky informacie su na pocitaci
  • TEMA: vytvorenie noveho projektu so pripravenym zdrojovym suborom main.c
  • — vytvorit novy projekt pre MSP430F5529 bez main().c
  • — pridat subor main.c  Vid.:  c:\STUDENT\PANCIK\Cv2_1_GPIO\main.c – preblikavanie LED-iek (CERVENA LED P1.1 a ZELENA LED P4.7)
  • — krokovat projekt
  • — modifikovat subor o opakovanie preblikavania LED:
  • main.c

}

// return 0;
