Hi,

Com 3 shows up in the device Manager, but i can get no output in Terraterm.
Several of my Modules, same Problem.
Any Help appreciated.

silly question because I'm sure you checked, but did you check the baud rate?

Silly answer,
what IS the baudrate, manual says nothing about it for USB, if you know it, why dont you say?
I tried several rates...Edited by atmega8 2016-09-10

38400 is the default baud rate.
Sometimes if the USB port can't supply sufficient power, it will create the com port but it won't communicate.
Being Win 10, I presume you don't need the SC driver?
Haven't connected mine to Win 10 yet here.

I find the USB to be more of a pain in the posterior then it helps most of the time.
On W10, you should not have any driver-related issues as has been mentioned, but anything Windoze 8 or lower will need the Silicon Chip VCP driver to be installed.
With W7 this is reasonably painless, with W8 you have to jump through some more hoops, but it can be done with a little more time spent.
Purely out of interest, do you get a response from the module using the native serial console and an external TTL-RS232 or TTL-USB adaptor?
I don't think that the PIC32 USB console cares about baudrate. From what I remember, anything will work, and the USB host in the PIC32 will adjust to whatever speed you care to set in TeraTerm or similar. The default is indeed 38k4, so that would be a good starting point, but I think that on USB, any baudrate up to about 1Mbps should work - I might be wrong, but I seem to recall that the internal USB console does not care about the baudrate, that is only relevant for the native serial console - I think.
Explore-64 Version 1D will most likely have the 1455 USB interface chip on it which should solve 99% of all these USB issues. I am already working on the version 1D board which adds the 1455 USB host chip, and adds a bit more filtering around the SD card power etc, to help fix those hiccups with the SD card. This is still a month or so away though, as I have only just started to look at doing these mods for a 1D version of the E64 board.Smoke makes things work. When the smoke gets out, it stops!

Hello Grogster,
i reprogrammed the modules with the latest Firmware.
Now everything works fine, also with WIN 10.
I don't know what went wrong.
If your nice Explore-64 Version 1D will we be available, i will Order some
of them.

If you mean the other thread where I wrote a reply in German, then yes. But I am also learning German slowly in my spare-time, and Google Translate is very useful, as you can get it to pronounce the German words, so I can practise how to say them.

The Explore64 and 100 look to have lots of pins not taken anywhere - is that right and if so why?

Don't think that's the case when you look at the schematics.
They appear to be all utilised.

If you work with mmbasic, instead of 'C' you have enough time to learn another Language like.🇩🇪, or🇫🇷🇰🇷
Another reason to say Thank you to Geoff 😉😉

Oh... I was looking at schematics ... maybe not the right ones or something. Found them in http://www.rictech.nz/files/132/file/Explore64-Constructors-Pack-zip and http://www.rictech.nz/files/136/file/Explore100-Constructors-Pack-zip
I'm probably looking at the wrong things (or looking at them wrongly!) but not having SC may be the underlying problem. No worries as I suppose more will be on Geoff's site soonish.

Depending on how you interpret this, then you could say that lots of pins are taken nowhere.
They are ALL assigned in one way or another, but many of them are routed to the likes of the Chick board sockets and the GPIO header. If these pins are not actually used by you, then technically you could say they go nowhere.
Invariably, there will be some pins you will never use, but they will appear to be routed out to somewhere - even though you are not using them.
I am pleased you found the constructor's packs - that's what they are there for. Smoke makes things work. When the smoke gets out, it stops!

I think it's just me. I'm used to seeing the outline of a CPU (on some schematics shown more than once) with its pin numbers all shown on the outline(s).
On the E100, for example, are (a lot of) the numbers actually CPU pin numbers? I now think they must be but didn't realise that.
