On Pyboard D the SD card is not automatically mounted. So you have to mount it yourself. Okay, that's good to know. So my SD cards are probably fine, and the fault seems to lie with the Crow Pyboards. There are eagle files published on their wiki but I don't have the skill set to understand them. P...

I followed those steps exactly. I even formatted the microSD card in Windows 10 and tried using it, with both the Class 4 card and the SanDisk Extreme card. Both cards are visible in Linux and in Windows, but when I plug in the Pyboard 1.1, the only thing visible is the PYFLASH space. I can't seem t...

So am I understanding that the problem is with the board definition of this Crow Pyboard? I'm a little out of my depth here.

Both boards are version 1.1. The micropython versions I've tried are both stable release versions, 1.9.4 and 1.10.0.

I will try earlier micropython versions and the latest master to see what happens.

I have been trying to get this to work for an inordinate amount of time. I have tried with a Class 4 4GB card and a SanDisk Extreme 32GB SDHC card and have had no luck. Both filesystems can be mounted on my Linux system. I tried with no partitions and making a fat32 fs on each card (/dev/sde) , and ...

I am not sure where this post belongs. On the ESP8266, when I try to use select to poll a UDP socket, I am getting POLLHUP? errors: >>> import socket, select >>> sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) >>> sock.bind(('0.0.0.0', 2001)) >>> poller = select.poll() >>> poller.register(so...

I've been doing more research into what might be involved here. It seems if I were to flash MicroPython on this WiFi skin that I'd have an issue with using a UART. That is, using a UART would conflict with the REPL on the esp8266/Wifi Skin. Would the fix from this commit work around this? https://gi...

I think you're right. I am fairly new to the esp8266/32 and I had not heard of those commands before. The last time I used AT commands was with a telephone modem. It looks like the Espressif AT commands (I think this is their latest firmware): https://www.espressif.com/sites/default/files/documentat...

That's the one. I have been looking at the basics of SPI communication. I hope to either do I2C, SPI or UART to talk back and forth. There isn't much documentation on the WiFi skin available aside from a little sample code, a schematic and some AT commands. I think I could learn a lot by hacking som...

I went ahead and ordered one of these Wifi Skins. It is on its way but will take a few weeks to get here. I got a Pyboard too. I'm beginning to accumulate a small pile of various boards. It's cheaper than drinking though. :) My question is, since this board is connected to the Pyboard by UART, could...
