Re: booting main.py

You can place all your files in the root directory of the board file system. You can also place your library into the "lib" subfolder. A third option is to create a sub-directory say "mydir" and then, you can append the "mydir" entry into the sys.path list. Place your starting code inside a file nam...

Re: Pyboard + W5500/W5200 Ethernet - getting it to work - MicroPython v1.11-422-g98c2eabaf

@roberthh I did finally get it to work with your firmware and many hour of labours: 1) I did trash all cables et use new ones (after continuity test) 2) replace the Ethernet cable and use one of a running computer... (being paranoiak is not excessive) 3) Change every pins used on the pyboard (so SPI...

Re: Pyboard + W5500/W5200 Ethernet - Cant get it to work - MicroPython v1.11-422-g98c2eabaf

Thank @roberthh for you quick response and the efforts put in the triple checks. I think that the compiled network firmware available on MicroPython.org is not complete. I got the following error when I activates the nic. >>> nic.active(True) Traceback (most recent call last): File "<stdin>", line 1...

Re: Pyboard + W5500 Ethernet - Cant get it to work - MicroPython v1.11-422-g98c2eabaf

@roberthh Robert, sorry to bother you but it seems that you are very skilled with the Ethernet support on the Pyboard. On this current thread (see initial message), I'm trying to use a W5200 et W5500 modules that never get connected to the network. I even tested the W5200 modules down to network fir...

Pyboard + W5500/W5200 Ethernet - Cant get it to work - MicroPython v1.11-422-g98c2eabaf

Hi, I'm trying to finish a book about MicroPython and surprisingly I'm getting in trouble with the Ethernet W5500 driver on the Pyboard. EDIT 2019 oct 13: Since this thread was opened, a solution was found. See the Wiring and additional information along this thread. I can't get ETHERNET W5500 modul...

DAC.triangle - Wrong frequency generated

Hi There, I wanted to generate a triangle at 60 Hz on my original Pyboard 1.1 (firmware v1.11-126... on 2019-07-05) After documentation read, I did wrote this small snip of code: >>> import pyb >>> dac = pyb.DAC(1, bits=12) >>> triangle_freq = 60 >>> sample_freq = triangle_freq * 2048 >>> dac.triang...
