SPI and ADF4360 PLL

[Roberto.Ambrosone]

I have to make an a oscillator with PLL adf4360.
It uses the SPI interface.
I really need some info on flowcode and SPI.
Why the window SPI flowcode tells me that the component has no external connections?

thank you

how I can help windows start the context of the window open?
SPI window has the help but it do not start.
I found the file spi.help in the directory flowcode

thanks

Hello Roberto

Let us know if you cannt get the device working and we should be able to point you in the right direction. Ths SPI component has no external connections as it uses the hardware SPI peripheral pins. Eg SDI, SDO and SCK plus an I/O pin of your choice for the CS line.

I COMPLETED THE PROGRAM AND I TRIED IT ON A PLL TSA5511 TYPE WITH INTERFACE I2C.
THE ADF4360 PLL HAVE SPI INTERFACE, WITH THE CLOCK DATE AND LATCH ENABLE .
CONNECTIONS FOR CLOCK AND DATA ARE (16F876A) PIN14 PIN15. HOW TO CONNECT THE LATCH ENABLE?

I SHOULD USE Pic16f876a To drive the two PLL CHIP.

I HAVE NO NEED OF CS (CHIP SELECT).
I NEED LE (LATCH ENABLE).

FLOWCODE CREATE AUTOMATICALLY THIS SIGNAL LINE?

YOU KNOW SOME ROUTINE IN C LANGUAGE THAT MAY BE IN MY HELP?

Hello Roberto

The LE latch enable input sounds like a chip select to me. You should be able to use the SPI component in Flowcode to communicate with your device. You can either manually set and clear the chip enable output or get the SPI component to perform this for you.
