Bus Pirate Support / I2C bus slowdown
Hello,
I would like to use the BusPirate to sniff a I2C bus and if possible to inject commands. My concern is that this particular bus runs slow, like 12kHz.

Would It be possible to slow down the I2C feature at that speed?

I see there is a RAW mode that could be set @5kHz but probably using the I2C feature could be better.

Any chance is there a firmware "hack" to create such a feature?

I could use a Raspberry PI (that should be able to slow down the bus) but I would rather prefer to use the BusPirate for both sniffing and injection.

Peripherals should support 100kHz no problem but at least one component is bitbanging the bus, so I am not sure yet it would work @ 100kHz.

Thanks in advance.

Open Bench Logic Sniffer / OLS - Digilient Spartan3 Original board support
Hello,
I would like to know if the latest version of OLS still does support the original Sump board, thank you. I had also the Oakmicros protective board for the inputs.

I need to fiddle with i2c, so I both need high speed analysis (better up to 1MHz) and I2C arbitrary data generation.
My idea was to stick with this board for sniffing and use something like the I2C provided by Devantech (or buspirate maybe) to interact with the I2C using Lazarus(using a serial port for example).

Thanks in advance.
