Anything in the archives yet? ASM or C would be fine.
Manual channel and trigger.
Thanks. Jim
Hi Jim,
Not yet, but we're working on it! What exactly is it that you are trying to do?

Tom,
Thanks for the quick response.
The design task is a 32 channel EEG data collector which both stores the data locally on an SD card and transmits it to a PC via Bluetooth in real time. The BT and SD are handled by coprocessors with UART interfaces. Each data channel is 0.1 to 70 Hz sampled 250 times per second. I am looking at a bank of 5 8332's (we need a calibrate channel for each 8332/OpAmp set and some spares)
A prototype exists based on the MSP430f5435 which works (it is actually in FDA test) but sort of grew like Topsy so a complete redesign is in order.
EEG signals are much weaker than EKG (a la ADS1198) so we are pretty much starting from scratch. The 8332 looks like a good fit.
I have done a lot of I2C but the SPI protocol seems much looser. No start bits and Full Duplex.
Thanks,
Jim

Very interesting! I've got something to share with you off line, so I'll be in touch...
Dear sir,
I am trying to SD CARD interface in MSC1210 for data logger, SD CARD is SPI Protocol , can you help me?, spi init and sample code for SPI and SD CARD
interfacing in MSC1210. please send sd card sample code. I am waiting for your valuable reply.
Thanks and Regards,
