Re: ESP8266 and JSN-SR04T-2.0 inconsistent results
Sorry to resurrect this topic. It seems your comments are opposite to the code: #Set and hold the trigger low. import utime trigger.value(1) utime.sleep(2) #Set the trigger high for 15 microseconds trigger.value(0) utime.sleep_us(15) trigger.value(1) and I'm wondering is you keep trigger low for 15 ...

How to compile firmware?
Hello, is there an up-to-date tutorial on how to compile Micropython esp8266 firmware? My goal is to byte freeze my code into the firmware. I was looking at pfalcon's: https://github.com/pfalcon/esp-open-sdk but it's not supported anymore and a lot of library dependancies are broken, so I can't real...

"Logging" module, write to file
Hi, I've got a Raspberry Pico and I want to log the errors to a file on the flash. I'm looking at the "logging" module, but there is no documentation for it. I listed the methods in it, but I can't find an alternative to the logging.FileHandler, which is in "big" Python logging module. So how do you...

POST request headers
Not particularly a uPython issue, but someone might help. I'm trying to use this code on esp8266 https://github.com/cpopp/MicroPythonSamples/blob/master/MicroPythonSamples/networkconfig.py for sending POST request to the form. However when sending the data from Safari, no POST variables are passed t...

Re: IRQ debounce
I think I solved the problem with the following code from machine import Pin,Timer import utime rain_count=0 rain_sensor=Pin(7,Pin.IN, Pin.PULL_UP) timer = Timer() def tipped(timer): global rain_count rain_count+=1 def debounce(pin): timer.init(mode=Timer.ONE_SHOT, period=200, callback=tipped) rain_...

IRQ debounce
Hi, I have a rainfall sensor which I've hooked to a Raspberry Pi Pico. My testing code is the following: from machine import Pin, disable_irq, enable_irq import utime rain_count=0 rain_sensor=Pin(7, Pin.IN, Pin.PULL_UP) def a(p): global rain_count state=disable_irq() utime.sleep_ms(50) if p.value():...

porting function for IP5306 chip to micropython
Hello, I'm struggling waking up a TTGO t-call board from deep sleep when board is powered only on battery. It appears the power chip ip5306 (an i2c device) powers down the whole circuit if the current is minimal, such as the case with deep sleep of the onboard esp32. There seems to be a solution by ...

Re: TTGO T-WATCH-2020
Great! Just flashed it and it works good so far.
I haven't dealt with wasp-os before and I need to figure out the file structure and how to get wifi going. I'll follow your progress on this

Re: TTGO T-WATCH-2020
if you have a compiled binary could you please upload that to your git repo? I just got my watch and want to try it without compiling from scratch.
