stm32f429 GPIO input impedance
Will there be any input impedence for the gpio's of stm32f429
If yes what is the value.
Hello
The GPIO impedance depends on the configuration.
As you talk about "input impedance", I assume that GPIOs are configured in digital input or analog input, in this case GPIOs are High impedance if no pull(up or down) resistor activated.
GPIOs have internal 40kOhms pull-up and pull-down resistor that can be internally activated see Table 56 in stm32f429 datasheet : DocID024030.
Hope that answers your question
