Hi. I am using the BME280 sensor with ESP-12. i measure indoor. (unused room) and the place of the esp board does not change Im running script one per hour an goes deepsleep. I use 2 lipo battery and HT7333 ldo. My questions is why the pressure values are unstable. DATE TEMP HUM PRESSURE 2017-09-18 ...

Hello deshipu, vahithosan, @vahitosan : Is your modified version of the lib do the trick ? I mean, in your 1st post you wanted to use an external DS3231 in order to wake up an ESP8266 from deepsleep. Did you succeed ? This is exactly what i want to do. @deshipu : can you confirm you didn't merge th...

I am interested in this issue (especially Modem sleep) because ADC is unstable wifi on.

Hi, I need to store exact time and date for my city. So, I inserted in boot.py the following code: from ntptime import settime settime() so, I can read time by: import utime utime.localtime() Isn't there a timezone support and legal/solar time support ? How I to do ? I think . You will use rtc. imp...

I'm not sure if that helps, but you can always use the _register and _flag methods on the urtc object to talk to the chip directly, and thus set whatever settings you need. Thanks. I just started working on micropython. Your library file was very instructive I made changes to the urtc file. Because...

I guess there is still a bug in the DS3231 alarm handling in that library, but I can't figure out what could possibly be wrong. Thanks for your efforts. I think there are 3 conditions for alarm activation. INTCN==1 and A1IE==1 and A1F==1 A1F is 1 when the time and alarm match For A1IE; At first 0x0...

I am confused when working with ds3231. I dont understand how the alarm works. I want an alarm every minute. I can not see changes in 0E and 0F. [code] import network import utime import machine import urtc import ustruct import network, time from ntptime import settime from machine import I2C, Pin ...

Hi. I have nodemcu v3 and DS3231 rtc. I want to use external rtc for high accuracy. And I want to awaken the ESP8266 from sleep with this rtc. I connected the RTC's SQW to reset terminal of the ESP8266. But nothing is happening. I use urtc on 1.9.1 firmware [code] import network import time import u...
