Hi , finally i found my beloved explore 64 1.b from rictech.
( hidden in an old project) . Unfortunately i can’t connect with usb serial , i get no data in teraterm under win10.

Geoff‘s site say i need a serial modul for , but if i remember right i never need one for this module.
Whats wrong , serial port will open if i connect the modul but no data ? Is it me , windows , the module itself?

Thx for help

The original Explore boards did use the inbuilt USB but later versions included a 'microbridge' to enable programming the firmware and run as the console normally.

The 1B boards use the inbuilt USB console (I think).

I remember having to install the USB driver to get my Explore to communicate. The driver should be listed on Geoff's site.

Jim is correct, and there were several versions of this module.

1A: Original version - prototype, not generally sold.(PIC32 USB)
1B: First commercial release (PIC32 USB)
1C: Updated release, added 130 CPU voltage monitor chip thing
1D: Added 1455 daughterboard you could plug into the top of the module
1E: Moved 1455 USB chip to the module itself
1F: Moved W25Q memory CS pin from pin1 to pin30

Which one of all of those variants do you have?


EDIT: Whoops, you said 1B.  This version does need the USB driver installed.  All other versions do not, as the 1455 chip on either the daughterboard or with it included onboard, are natively supported in Win10 and usually Win8 also.  You might need drivers for Win7 even with the later versions.

Years ago my E64 reached a point where I could reflash it, but could never get a prompt. I didn't pursue the issue for long.

W10 device manager should indicate if a driver is needed.
After you get Teraterm to connect you will need to work out what baud rate the E64 was last set to.

I've had like 5 E-100s and apart from that initial issue with the driver (oh but I was using XP), never had a problem.
I still have an E-100 that I use for testing Mikroe Click modules.

A Picomite with Click sockets would be cool

I've never even seen a Click socket. Are they available or some sort of proprietary thing? I'm sure some sort of add-on for a PicoMite could be done.

After a reflash with a compare read the chip will not work. A new clean with isopropyl make it run!
Unfortunately the old basic programm is killed.

When using the inbuilt USB console connection, the baud rate is not relevant.
Any setting should work.


I don't think W10 will enumerate the port if the chip is not functioning at least partially.

If you had AUTORUN set, you may be stuck in a loop and need to reset the device.

Sending a stream of exclamation marks (!) to the console on boot is still the method but can be trick to get the done quickly enough with the USB connection.

Reflashing might be easier.

Found the spec on mikro BUS, Craig. Would you like me to see about a PCB? It would probably have 2 sockets as there are two of each sort of interface. It would use up a lot of I/O pins though (20 min.).

Yes, the E100 board had a couple of Click sockets also, and last time I looked, there were lots of different modules to choose from, but I myself never used any Click modules.

@ Mick - if you do a layout, make sure to allow for the long version of the Click module.  Or simply allow for it to stick out the top of the PCB or something.

Yes/No  

I have this other thing coming your way and thus far it has 4 Picomites, a Prop-2 and 156 I/O

On the Explore-100, the pins are not necessarily tied-up with the Click sockets. They are also brought out to the headers.

The neat thing about these Click modules is that they are tested/proven circuitry and they also provide the module's schematic and sample code in BASIC (albeit MikroBasic).
Simply download the file and unzip it (they have their own file extension but it is actually a zipped file).

No prob - nice to see a proper one. :)
I hadn't realised that SPI and I2C could be shared or that RST was individual to the module. I didn't bother with level shifting either - it's 3V3 or don't bother.
I'll not chase it further.

Actually, Mick....

I think I might be interested in a Click socket with one of those tiny 2040 modules...just had a cool idea
