Hi guys,
I'm have problem with RC3700.
I use RC3700 and development board with DC9.25.
I use ADC and serial flash together but ADC not work.
If serial flash disable, ADC run normally. After i'm check, PB0 use
together for ADC on development board and serial flash on RC3700 for CLK.
Can you give me pointer what i'm must doing ? Or maybe you have sample
program like i'm doing ?
Thank you very much.
Regards,
Stev

First off, upgrade to Dynamic C 9.62 and try again. The RCM3700 was designed so
the serial flash and ADC use separate chip select pins so they can share the
other SPI lines.
Are you using the APIs provided in RCM3700.LIB and SFLASH.LIB? They appear to properly assert/deassert the ADC and flash chip select pins, so the shared SPI bus shouldn't be a problem. Perhaps there was a bug in that code in Dynamic C 9.25, and it was fixed before the 9.62 release.

Dear Tom,
I'm already upgrade to DC 9.62 and same result, ADC value still 0.
I'm use RCM37xx.lib included in folder sample/rcm3700 and sflash.lib.
Thanks.

Stev,
Please email me your test code off-list (t...@tomlogic.com) and I'll take a look at it when I'm back in the office later this week. I'd like to see an example program that has valid ADC readings until it accesses the serial flash. My goal will be to make updates to the program or libraries so the ADC continues working after reading/writing the serial flash.

Tom, thanks for your attention.
Problem already solved. I'm make mistake on my software, cs for adc always
low.
