ntp issues

I try to sync to ntp every hour, as the rtc drifts too much otherwise ... I discussed this in https://forum.micropython.org/viewtopic.php?f=16&t=7483&p=42589&hilit=ntp#p42589 Starting a couple of weeks ago, ntp updates fail after a few hours, and thus my esp8266 clocks drift wildly. Has anyone exper...

RMT class bug

Hi, Today I was playing with the RMT class, and noticed what appears to be a mult-legged insectoid: import esp32 from machine import Pin r = esp32.RMT(0, pin=Pin(27), clock_div=80) r.loop(1) r.write_pulses((100, 5, 10, 20, 10, 30, 10, 40, 10, 50, 1,1), start=0) Note the initial long low pulse, and a...

Re: uMail - A lightweight SMTP client for MicroPython

The issue appears to have been with MicroPython.

After flashing the latest build from

http://micropython.org/resources/firmwa ... 0abcf2.bin

umail worked again :)

Re: esp8266-20191220-v1.12.bin issues

I will try a timer interrupt, hopefully the micropython timer handler will still fire if the main python code crashes. I added a few try/excepts, hopefully they will catch what crashed the board last night. I may look into the possibility of a C task for the RTOS to implement a watchdog. The esp8266...

Re: esp8266-20191220-v1.12.bin issues

Agreed, however it is dissapointing. Not blaming uPyghon. Hmm.. it should be possible to compensate for it by having a 'tuning' variable say in boot.py 2) the RTC is extremely inaccurate, on the order of being off roughly one minute per hour of run time. Think this is a hardware issues, isn't it?

esp8266-20191220-v1.12.bin issues

I am trying to move some simple projects to ESP8266 NodeMcu boards instead of ESP32 boards. I flashed the boards with the latest stable release. Two issues so far: 1) the watchdog does not take the documented parameters, so I can't set a longer watchdog timeout Suggestion: The watchdog should be dis...

Re: uMail - A lightweight SMTP client for MicroPython

Great library, fantastic support.

My bad, I had connecting to my wifi commented out.
