'[PIC]: interfacing PIC16F877 with AD7713(adc)'

Hello Sivaram & PIC.ers,

One of my designs uses the I2C bus, controlled by the 16f877 MSSP.
It *also* has to communicate with an ad7715  16bit adc, this has an
SPI digital i/f.

Apparantly it's possible to run both I2C and SPI from one MSSP in
the PIC, but my attempts failed so I ended up doing the SPI > ad7715
in software. No big deal... at least the SPI bit, as for getting the adc
and PIC to talk sense to each other - a whole nother deal.
If this is of any interest to you let me know.

       best regards,   John

Hi,

We use an AD7710 in a project and have a 5.1K resistor between SDO and
SDI (MOSI and MISO). The SDI line is connected directly to the SDATA I/O
line of the 7710.  There are additional pins going to the A0, RFS and
TFS lines to select registers and reading/writing.

The same board also has conventional SPI devices like EEROMs and those
signals are connected directly to the SDI, SDO and SCLK of the 877.

I have one function for all the SPI communications and a special
function for the AD7710 communications and I do use the hardware SPI
registers to do all this.
