• pullup resistor value for I2C
    Hai.... I have a problem while reading the eeprom. while reading it i got some garbage values which i was not stored in eeprom. i think it may be because of pullup resistor. Can anyone please...
  • Reg: keypad needs pullup resistors
    Whether ordinary 4x4 keypad requires pullup or pull down resistors to be connected in order to generate signals.
  • uVision simulation of external pullup resistor
    Hi all, For an LPC2132 application I required a third I2C bus and implemented this using bit banging of GPIO pins. A logical 0 is implemented by driving the GPIO pin to low, a logical 1 is implemented...
  • pull down resistor
    im using lpc1768 i connected button to P0.5, led to P0.4 initially the button pin should go low, if i press the button P0.5 should get high but the pin is always high i checked the pin with multimeter...
  • Avoid pull-down resistor
    How can I avoid pull-down resitors during reset and configure de C167CR manually? After reset the microcontroller I can see with the scope that data bus signal are not good, it falls down slowly and...
