Esp8266 Gpio Pull Up Resistor

A lower value resistor will pull the pin up harder making it more. When i do the pull up manually with a resistor my wiring works perfectly but when i add an internal pull up using the following line in my arduino ide code it does not work properly.

Esp8266 Reading Writing Gpio And Transmitting Receiving Udp

The esp8266 has a single analog input with an input range of 0 10v.

Esp8266 gpio pull up resistor. For gpio0 and gpio2 an external relay must be connected between vcc and the pin so that it does not interfere with the action of the pull up resistor. Gpio16 has a built in pull down resistor. Would it be okay for a long shot.

Im using 47kohm resistor as pullups for gpios 20216 chpd and reset and also 47kohm pulldown for gpio 15. Unlike most atmel chips arduino the esp8266 doesnt support hardware pwm however software pwm is supported on all digital pins. Resistor pull ups for esp8266.

Should i use 10kohm instead of 47kohm. Conversely an external relay connected to gpio15 must be connected between gnd and the pin so that is does not interfere with the action of the pull down resistor. Below is the descriptions of gpio that you can refer to.

Dear bugless the value of internal pull up resistor is between 30kohm and 100kohm. The esp8266 boots and works fine. I am working on the adafruit feather huzzah esp8266 and i would like to add an internal pull up to a push button.

The default pwm range is 10 bits at 1khz but this can be changed up to 14 bit at 1khz.
