Can you make it available with upip?
like:

pi$>micropython upip import usqlite

I managed to compile Micropython + usqlite on my Raspberry Pi .

Hi! FYI. this is my Wemos D1 Mini' memory. MicroPython v1.15-4-g5669a6095 on 2021-04-23; ESP module (1M) with ESP8266 Type "help()" for more information. >>> import gc; gc.collect(); gc.mem_free() 33440 >>> import os; s=os.statvfs(''); print('%.3fkb free of %.3fkb'%(s[0]*s[3]/1048.576, s[0]*s[2]/104...

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...

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.

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...

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...

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...

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...

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...

The moment this is execute the above line of code all the LED`s turn on RED and stay that way

I had similar issue. Solved by powering the LED matrix from an external powersource, such as battery or Lab Bench PSU.
