Hello All,

I've made some progress. At least the MISO pin is "singing" with 1's and 0's. But I can't seem to get the chip to record or play. I'm using the LED off of pin 2 as an indicator. I even put a test probe and monitored the pin 2 just in case the LED was put in backwards.

I also started monitoring pins for more "foolproof" software rather than guessing at delays. One of the things I realized that after sending the record command, 0x51 (bit 4 set for LED) and 0x00 (data byte), the interrupt bit in SR0 never gets set. And according to the datasheet I believe it's suppose to get set after executing that command. I also tried sending the stop command right after the record command, thinking that maybe the interrupt bit is set after the record command is stopped, and this still doesn't result in the interrupt bit being set.

I just want to make sure I'm using the latest datasheet. Is revision 1.1 from May 2007 the latest?

Thanks, Alan
