Hi, I have the file NUCLEO_L476RG-20210902-v1.17.dfu which I would like to flash to my NUCLEO-L476RG board. However, I think I can only flash a .bin file. I flashed a *.bin from MBED and it worked great! How can I convert this *.dfu file to a *.bin I can flash to my board? The command I use to flash...

You can alway add lib to sys.path in your main.py.

import sys
sys.path.append("/lib")

That is not working.

Hi, I just built and deployed the latest v1.16 version of Micropython to a Teensy4.0. I2C seems to be working. I can do i2c.scan() and detect all devices on the bus. # Import all board pins. from machine import SoftI2C, Pin TP_SDA = Pin(18) TP_SCL = Pin(19) # Create the I2C interface. i2c = SoftI2C(...

I have been working on my Micropython HT16K33 library . I added a feature that allows automatically rounding an input number. It will round up to the point where there is no decimal part in order to fit it on a display. There is the same ability to specify the number of decimal places to round to. F...

Hello, I am porting Adafruit's HT16K33 library to Micropython and am making very good progress! However, there is one gotcha in the Adafruit code, which is a (theirs) board.I2C.try_lock(). It is used to tell when the i2c bus is available. Could this be easily added to Micropython's machine.SoftI2C()...

Hi, I am still having problems with my imports, and I do not understand why. Why does Micropython not allow me to do something like from ht16k33.matrix import HT16K33 I really do not understand this. No matter what I do. I can not seem to get my imports right. I have attached an archive with the exa...

Hi, I have a tinyPico with Micropython and am getting the dreaded Error 19. There is nothing connected to the tinyPico and I have already erased flash and reflashed Micropython to the board. This did not have any effect. I have attached the complete library I am working with now - hybotics_ht16k33 i...

So something is not as it seems. I'd check exactly what is being imported by putting a print statement as the first line in each file I found the problem! There were TWO copies of the library - one in the root directory and the other (correct) on in /lib. I feel so stupid right now. Micropython was...

The problem I am having is that the import statements work inside the REPL, but they throw errors when in my code. This what I am trying to figure out. Here is an updated archive with a new test program - import_test.py I believe. All it has are various forms of import statements related to my libra...

Hello, I am working on porting some libraries from Circuitpython and updating the ht16k33 library that currently exists for Micropython. I do not understand why the import statements do not work within the code file but they will work fine in the repl. I need some assistance here. What am I missing?...
