Hij is maar 55 x 43 mm groot (ca 17 mm hoog)<\/p>

De IC tester heeft 7 aansluitingen (van links naar rechts):<\/p>

  1. SCL (clock)<\/li>
  2. SDA (data)<\/li>
  3. Reset (MCP23017 te resetten)<\/li>
  4. Aansturing 2 kleuren led groen (goed)<\/li>
  5. Aansturing 2 kleuren led rood\u00a0(fout)<\/li>
  6. Ground<\/li>
  7. + 5 Volt<\/li><\/ol>

    Voor\u00a0Arduino versie die werkt op 3.3 Volt is het verstandig om voor de SCL en SDA aansluiting een level shifter\u00a0te gebruiken.
    Zie BSS138 4-ch
    <\/a>De werking is eenvoudig:Neem bijvoorbeeld de 74LS04 deze bevat 6 inverters.<\/p>

    Dan zijn van dit IC de pinnen 1, 3, 5, 9, 11 en 14 ingangen en 2, 4, 6, 8, 10 en 12 ge\u00efnverteerde uitgangen.Dus de MCP23017 moet voor de pinnen van de 74LS04 als OUTPUT\u00a0geprogrammeerd worden en voor de pinnen\u00a02, 4, 6, 8, 10 en 12 als INPUT.Als je nu bijvoorbeeld op (74LS04) pin 1 een HIGH instelt, dan verwacht je op pin 2 een LOW.En pin\u00a01 een LOW\u00a0instelt, dan verwacht je op pin 2 een HIGH.Zoniet dan is dit deel van de 74LS04 defect.Je kan dus een logisch test casus maken voor iedere logisch IC.PS. De GND van een IC kan je gewoon op de MCP23017 uitgang aansluiten en LOW maken, de VCC + 5 V ook maar dan wel HIGH)
    Uiteraard moeten deze 2 ‘voedings’ pinnen als OUTPUT gedefinieerd worden.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
