Not a USB podule but a way to connect a USB mouse (or keyboard if I can finish the software).

Looks very professional.

Very nice and definitely needed. Does this work on any Arc with a standard podule slot?

[cmj6502]

The boards are from JLCPCB. I’m pleased with the result.

I’m hoping it will work on anything with a podule connector but have been developing it on a risc pc.

Still a work in progress - more software to do, and at least one PCB error to fix (mine).

Cool.

Now seen by *podules

Interesting.

If you are looking for feature-creep, can I suggest joystick support? You could probably use most of USBJoystick for the HID-to-SWI stuff.

This isn't entirely serious. I have done nothing with USBJoystick itself for a long while! But it could be a bit of polish for a rainy day...

Nice!

I had no idea there was such a thing as a microcontroller with USB Host capability in a DIP package

[cmj6502]

Progress - I've added the second PIC so it can now talk to TWO devices The LEDs change colour depending on what's plugged in - purple for keyboard and green for mouse

On the downside - the podule talks to the PICs over I2C, which means it's spending a lot of time in IIC_Control which runs with interupts disabled. Need to think about this a bit.

The PIC can do it, so it’s possible. One for the to do list

[cmj6502]

another update. In order to speed up transfer (to not spend too long checking the pics every timerV) I have changed from IIC to SPI. It’s looking promising, although will need a redesign of the board.

Is it just me, or have the images in this thread gone missing?

Edit, ah they are hosted on imgshare:

Not just you. Images are on an external site - e.g. https://imgshare.io/images/2019/08/14/1 ... 115134.jpg
I guess they do some referer checking to prevent linking. (Even that link may not work, if you get a 404, try a refresh)

[cmj6502]

It’s probably me. I need to sort out some hosting.. it’s on the list. If only this work stuff didn’t take so much time!
