I had rshell working for a while, but now it is failing. I filed https://github.com/dhylands/rshell/issues/138, but I wonder if it is because of the fancy UISHELL ascii logo?
This is on the Atom Mini, so it's a bit tough to figure out!
I'm running v1.6.2-lite on it, and REPL says:
MicroPython 400ff3bbf-dirty on 2020-08-06; M5Stack with ESP32
Thanks, once I got the other computer to see the device (can't flash a device that doesn't show up in device manager), I was able to reflash it.
Then I took it back to my laptop, and it still wasn't seeing it. So I switched USB cables, and it did. Then I switched back to the original USB cable, and it worked with that cable again. (Note that I had hooked up a M5StickC via the original USB cable, and it is working fine with that cable now, so the cable isn't bad).
Gotta love Microsoft Windows sometimes.
This was the super-frustrating "windows doesn't recognize a device. But a different windows computer does". :(
I hooked up a 10K resistor and a CDS cell (resistance 50k-1M) in series from 3v3 to GPIO36. I set the pin to ADC mode, and was reading between 3000 & 4095.
But now the gray isn't working. It doesn't show up as a serial port on the PC. If I try playing the built-in rock/paper/scissors, it goes black as soon as I push a button (https://claar.org/gray.mp4).
So, did I kill my gray? If so, what did I do wrong? I don't want to repeat with another piece of hardware!
Google suggests that 10K should be plenty as a pullup, and an ohm meter shows that the resistance goes between ~60K to 1+M, so I didn't use the wrong resistor (and the CDS is 50K in any case).
I guess I misunderstood what support said: "If you are connecting through 3.96 terminal, 12V DC is required" seemed to say that I needed 12V to use the serial pins.
The http block you are using is for talking to a web site, not for being a web site. Or in more technical terms, it is a client, not a server. If you had a web server on your laptop, it could talk to that.
Looking at the other options, it looks like EspNow can listen for data, but I don't know if there's a laptop client.
mqtt is a client that needs a cloud-based server.
There's a p2p option under network, but that seems to be for talking between 2 devices.
Finally, there's remote, which it says "Remote control M5Stack via devices such as mobile phone or computer." I think that's your best bet.
I'm not patient. :) I broke down and bought this, although I don't know what I'll do with the other 4 units.
I was really excited about the new rs232 Atom kit, but unfortunately it requires 12V to power it, which it converts to 5V to power the Atom. I can see how that could be cool if you had full serial and could use one of the control lines. But I only have the minimum 3: Tx, Rx, Gnd.
So what are folks using to talk to "real" (full 12V) serial devices? I have some max232 chips laying around, but they're 5v, and the ESP32 spec sheet shows a max of 3.6 for pin input. I may have a level shifter somewhere, but that seems like overkill.
I guess I could get a 3.3V max232, but I'm kind of surprised that there's no ENV or HAT for this.
Hmm, but I can connect with the M5Stack extension in VSCode, although the Pymakr Console won't connect. I must just be missing something.
Ooh, in putty, if I type control-c, then I get to repl! So maybe rshell needs to do that.
I'm on windows. I've tried putty as well: It prints the banner and stops. Maybe I have the wrong baud rate (I'm using 115200) or something, but one would think that the display of the banner would fail then as well. For example, with M5Burner Beta's "COM Monitor" (button in the upper right-hand corner), typing os.listdir() and hitting Send gives me a crc error2k. This is only with 1.5, 1.4 worked fine.
