Re: Continuously reading ADC pins

My Pyboard v1.1 works well with this code :

Code: Select all

import pyb
import math
while True:
    adcint = pyb.ADC(pyb.Pin('X4')).read()
    print("Analog reading of port X4 = %f V" % (adcint*3.3/4095))
    pyb.delay(50)

Re: MemoryError when importing a custom module

pythoncoder wrote:@rcolistete This occurs when the compiler runs out of RAM: when you import a .py module the compiler running on the board converts the text file to bytecode, which is then run by the Python VM.
Thanks. My suggestion was to compare different MicroPython boards with respect capability to load modules.

Hello, I am working on a module for the MFRC522 RFID reader. The module size is 11KB I managed to copy the module on the micropython filesystem with the help of webrepl_cli.py. When I try to import the module through the UART REPL, I get the following error: MemoryError: memory allocation failed, a...

Re: Free RAM on MicroPython boards

My mistake, WiPy still has 56KB of free RAM for MicroPython 1.7 & 1.8.

Updated the 1st post.

Re: Free RAM on MicroPython boards

Updated the 1st post with approx. free RAM for LoPy (200 KB) and ESP8266 (22 KB).

So there is only BBC Micro:bit with unknown free RAM.

Re: Free RAM on MicroPython boards

Thanks.

But if anyone who uses ESP8266, BBC Micro:bit and LoPy could measure the free RAM and fill the "?" above, it would be very useful to the community port effort (from Python 3 -> MicroPython).

Free RAM on MicroPython boards

[Moderators note: please note that the figures are valid on the date stated, and may vary from one MicroPython version to another.] I need to know how much RAM (heap size ?) is available for the user in MicroPython running on : - Pyboard v1.1 (99 KB < 192KB), MicroPython v1.8.6 (updated in 21/11/201...
