freq ( 20 ) # set the frequency (can also get) tim2_ch. B, freq = 10000, duty_cycle = 5000 ) # start the PWM on channel B with a 50% duty cycle tim2_ch. POSITIVE ) # start the event counter with a frequency of 10Hz and triggered by positive edges tim2_ch = tim2. PWM ) # initialize it in PWM mode tim1_ch = tim1. ONE_SHOT ) # initialize it in one shot mode tim2 = Timer ( 2, mode = Timer. This makes handling with time data very easy and takes care of regular ntp updates.From machine import Timer tim1 = Timer ( 1, mode = Timer. I use the “time” – lib by Paul Stoffregen( ) together with my ntp implementation. It’s blazing fast, almost a 100% reliable and more than good enough for all my projects. Since that day I am updating my time with that “server”. I then, more or less accidentally, realized that my router – typically the gateway address – also provides ntp services by default. Sometimes You have to click several time or change to a different server until it reports success.

#Esp8266 timer example update

You might have realized that on Your windows pc, when You try to manually force an update of the time by a time server. Unfortunately most of the time servers seem to be available only temporarily and the IP address becomes invalid from time to time and I had to implement a mechanism that detects that and then requests a new address.Īnother issue is that requests tend to fail quite often, probably due to high trafic. So I got the IP-address on the first call and used it directly on subsequent calls. When I implemented ntp updates in my esp8266 projects about two years ago, I realized that dns resolve to the time servers sometimes takes a good amount of time. dateTime = NTPch.getNTPtime(1.0, 1) //from NTP server use this if you want ESP to continuously fetch new timeĭateTime = NTPch.getTime(1.0, 1) // get time from internal clock The initWiFi() function initializes Wi-Fi and connects the ESP8266 to your local network. The getTime() function gets and returns the current epoch time. We’ll request the time from, which is a cluster of time servers that anyone can use to request the time.

ESP8266 NodeMCU Get Epoch/Unix Time ExampleĬopy the following code to your Arduino IDE. This function returns the current epoch time. Unsigned long now = timeClient.getEpochTime() To get epoch/unix time with the ESP8266, you can use the following function getTime(): // Function that gets current epoch time In this case, the ESP8266 is an NTP Client that requests time from an NTP Server ( ). There are NTP servers like that anyone can use to request time as a client.
