Can you make it available with upip?
like:
pi$>micropython upip import usqlite
I managed to compile Micropython + usqlite on my Raspberry Pi .

Micropython online simulator
Recently I discovered https://wokwi.com/ free Micropython simulator online. It seems as its integrated Micropython in a Raspberry Pi-backend with frontend functionality. Pretty neat educational effort :) beginners resources. https://github.com/pappavis/plaatjes_en_onzin/blob/main/img/wokwi.com_micro...

Re: Can't install adafruit-micropython-blinka
It may help if you create a Python virtual environment.
That way less chance of insufficient privileges.
You could try my script https://github.com/pappavis/thescript/b ... tualenv.sh which should work fine on MacOS too.

Re: ACS712 AC Current sensor not sensing anything
Sorry I created some confusion. :? This is the proper snapshot when the sensor is powered on. Weird is the signal moves from top to bottom. Not smooth at one (milli-) voltage level. I dont know why.. perhaps I am a bit inexperienced on using/reading 'scopes? I'm a Python support by profession. https...

Re: ACS712 AC Current sensor not sensing anything
I wanna measure low current AC power >=0,01A. Looks like the ACS712 5A-version isnt suited. So I bought more sensors from Aliexpress and done some more experiments with a ZMCT103C LM358-based hall sensor & current clamp. No joy. - The current clamp shows 0,038A current draw. - The ZMCT103C sensor do...

Re: ACS712 AC Current sensor not sensing anything
No results. Nothing. I'm stuck. :oops: I've connected my scope & multimeter connected. Setup on my Fnirsi DC-6006L bench power supply VCC to the ACS712 sensor: 5,01V Sensor consumption: 0,016A / 0,08W with no load active. Multimeter on output pin: 2,518V with/without load. HUH?! With a 8W LED bulb a...

Re: ACS712 AC Current sensor not sensing anything
I'm not making any sense of it :evil:, and tried without a MCU connected. Only the bare sensor. No voltage changes detected on the ACS712 OUT-pin :cry:. Heres wat i tried. With ACS712 switched off AND no load, measured = 377,8K ohms resistance With ACS712 switched on AND no load, measured = 2,503V W...

Re: ACS712 AC Current sensor not sensing anything
The 5A sensor has a six times larger output variation at the same current. WHAAT? I'm getting crazy. :( I bought a ACS712ELCTR- 05B -T (5A)-version which gives same results of 745 regardless of load :evil: . I used a 40W LED bulb on AC power, with Wemos D1 Mini (ESP8266). I tried my clamp meter, pu...

Re: Anyone working on a MAX7219 8x8 LED matrix display library?
I had similar issue. Solved by powering the LED matrix from an external powersource, such as battery or Lab Bench PSU.The moment this is execute the above line of code all the LED`s turn on RED and stay that way
