Hi

I thought it's already supported?

New Project > AVR Based > ATTiny shows the 88 and 88TQFP

Hope this helps
Regards

But I can not connect it. I have not drivers or something else. There is "Unknown USB device".

Hi Sergejs

To make your Attiny88 work with Flowcode,
I assume you need a USB driver for the Attiny88 for your windows system
You can find and install this online.

search for: USB driver Attiny88 windows

Hello,

USB could just be for power, I don't think the tiny88 is capable of USB comms and I'm not seeing an external USB IC though it could be on the underside.

It looks like there is the standard 6-way socket towards the top of the board for an AVRISP or USBtinyISP to allow programming.

A link to the eBay sales page might help.

Ok So it's a ATmega328 which doesn't have hardware USB, I beleive you can bit bang USB on an AVR but I certainly wouldn't recommend it.

Certainly the standard Arduino bootloader won't work as that uses a UART and a USB to Serial external IC.

So it looks like you will need an ISP programmer to reprogram the thing and you will have to be careful about which IO you toggle when powered via USB.
