Hi, web configurtion work nice now

. At the moment I am working on status page with mining statistics.

it will be going out monday now....sorry didnt get out today to post it

Ok,thanks.

At the moment I am implementing Web Configurator for Ardulon miner.

[UPDATE]
Ethernet part work fine but avalon is not working properly. I am waiting for another one.

This is universal miner with USB connection for minning via PC or with direct connection (via ethernet) to bitcoin pool.

Hi, Blue line represents REPORT_N and yellow REPORT_P

so IDLE, SEND1, SEND0, SEND1, SEND1,SEND0,SEND1,SEND1,SEND1 = 0xED - LSB BYTE

0xF78A00ED is received nonce

heh .. my bad point of view Wink

As long as I will not have another avalon for testing I'm working on the Ethernet layer for my miner

Hi Explorer232,

I tried to decode part of nonce, showed on picture.
If I'm right, the sequence from left to right on the picture is:

IDLE, SEND0, SEND1, SEND0, SEND0, SEND1, SEND0, SEND0, SEND0 it means 01001000 == 0x48h

But in LSB scheme it means 00010010 == 0x12h

It isn't part of 0xF78A00ED you decoded.Correct me if I'm wrong.
Or 0xF78A00ED is golden nonce = received nonce - 0xC0?

If it is faulty lemme know, I have a few samples left too, though I think marto's will get their quicker now...

I'll send you today another one

Thank you , I have only one chip at the moment.

This is one received nonce from chip.
Decoded - F78A00ED

Hi, I have problem with my miner.

1. I send config to Avalon (I checked this part many many times and it seems to be okay) LSB (first bit, byte, word) [8B - Clock Config] , [12B - data], [4B a1],[4B a0],[4B e2],[4B e1],[4B e0], [32B midstate], [4B a2], [4B nonce - 0x00000000 - 1 Avalon chip]
I use multibit transfer ---- IDLE first bit ...... last bit IDLE
Avalon is clocked to 256Mhz.

Precalculations: I think its ok. Precalculated values are generated from midstate & data. I could like to send precalculated values for specified btc block [data, midstate]

2. Avalon send me nonce, nonce is correctly decoded by arduino (checked by osciloscope)

3. Received nonce is shifted about 0xC0

BUT golden nonce is not valid.

Config frame:

I dont know if I have a bug somewhere or my avalon is faulty Sad

Arduino read / write config from/to AVALON correctly

Nice work!
Greetings to Slovakia from Ukraine! Wink

I have two questions:
- Will this shield be backward compatible with Arduino Uno?
- And what is needed to adopt the shield/rig board to bitfury's chip?

Thanks!

Very very very unlikely: the DUE has an ARM-A3 and communicates at 3.3v compared to the 328's 5v!

ARM-A3:
A 32-bit core, that allows operations on 4 bytes wide data within a single CPU clock. (for more information look int type page).
CPU Clock at 84Mhz.
96 KBytes of SRAM.
512 KBytes of Flash memory for code.
a DMA controller, that can relieve the CPU from doing memory intensive tasks.

Whereas an Uno has a 16Mhz 8bit CPU with 16KB of ram.

Loving the work btw, hope you get some bitfury chips! At 0.5w/ghash they look great.

Thanks for the answer!

Bitfury is out of testing chips right now. There's a big boom about this small hulk.
I saw them in my hands, but since I am not a skilled engineer, there were no use for me to take them alone.
But since the project for Arduino is kind of niche market and I like the idea, I will do my best to have the chips, when they will be available.

P.S. You mean, UNO is too weak to serve as a tunnel from ASIC-rig to Host (PC)?
