Re: USB-RFM70 RF transceiver adapter

Hi,
I needed more than 2kB of boot space, as my bootloader is >3kB (which includes HID bootloader plus a functionality to program remote AVRs through the RF module over the air). ATmega8 can be used if only HID-bootloader is enough.
Thanks

USB-RFM70 RF transceiver adapter

Hi all, Here is my project called usbXR, an adapter for RFM70/73/75 2.4 GHz RF transceiver: https://github.com/visakhanc/usbXR . The intention of the project is to communicate with other RFM70 based remote nodes bi-directionally from a PC, for any kind of application. It features the original HID-Bo...

Re: Simultaneous In and Out interrupt transfers

I have synchronized the input thread and the output thread of the C# application and now the crashing problem is solved. When the input thread received an interrupt in packet, an event is set so that output thread can send out packet. It seems like there is no collisions of in and out packets with t...

Re: Simultaneous In and Out interrupt transfers

Yes, I know v-usb will not give the real performance of usb chip. But the biggest advantage here is that it is the cheapest alternative for a usb enabled solution. And this opens up so much possibilities in my opinion. For now, doing In and Out transfers at same time really does some nasty things to...

Re: Simultaneous In and Out interrupt transfers

Thanks for reply.
I don't know that much about what is going on inside the driver. So it requires some looking up before I could find out what modifications are needed.

Simultaneous In and Out interrupt transfers

I have built an Hid device which is going to be used as a general purpose RF transceiver. I have successfully tested input and output transfers (separately) through interrupt endpoints at the maximum polling speed (around 8ms) with 8 bytes packet. This was done using separate C# WPF applications whi...
