Re: How to support the XY2-100 protocol for laser mirror sca

The problem I'm facing now is that my driver board takes 5v and my logic level converter is not fast enough to create a 5v square wave with the 2 Mhz signal produced by the board. I hope this is a small problem, any thoughts on how to fix this? I am hoping for an off-the-shelf solution. Please note ...

Thanks for your response, I have decided to go with a BeagleBone Black and found somebody to help me out, but it's always good to know some more options so thanks!

How to support the XY2-100 protocol for laser mirror scannin

Hi, I am trying to figure out how to support the XY2-100 protocol: http://www.newson.be/files/TD_XY2-100_R0703.pdf The signal looks quite similar to SPI. For a single axis I need to produce 3 signals: 2MHz clock Sync -> goes high on the first data bit and goes low on the parity bit Data -> 20 bits: ...

Re: I2S: Anyone got it running?

We've got the I2s interface woring with a Twisted Pair Buffalo DAC, as it doesn't require the master clock (MCLK) input. We're hoping to get it working with a cheaper DAC, hopefully with the Pi supplying the MCLK. The LRCLK translates to the PCM_FS available via one of the tiny resistors not fitted...
