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...

PYBD and WebREPL ?

Hi,
I was playing with my Pyboard-D SF2W and discovered that WebRepl was not available on it!

>>> import webrepl_setup
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: no module named 'webrepl_setup'

Is the WebRepl missing or replaced ?

Re: Change hostname.

Hi, I'm using ESP8266 under MicroPython. I had use the default ESP8266 hostname from WebRepl and find this really convenient when using the network DHCP. I'm using the modem-router from the Internet Provider. Using "ws://ESP_xxxx:8266" with WebRepl is really a dream. However, from time to time this ...
