Remony,
You need to configure 2 GPIOs as regular output pins and route them to your slave devices as shown below.
From Code configuration standpoint :-
Configure C2000 SPI as master device in normal 4-wire SPI mode (SPIPRI.TRIWIRE = 0)
Configure…
Hi, I have a couple questions about SPI on the C2000.
I would like to setup a master to multi-slave SPI bus, where an F28069 is the master, and there are three slave devices (MCP2515s, which are SPI-CAN converters). Along with SPIA-SIMO, SPIA-SOMI and…
Part Number: TMS320F28375D Hi Champs,
According to this TRM page 2127 on "Configuring a GPIO to emulate SPISTE",
C2000 SPI seems not support "multiple SPI Slave" connection like a cathcade.
However, GPIO is possilbe to emulate SPI slave. is it…
Hi Maria,

I think we determined that if you are SPI master, you shouldn't have any problem using GPIOs for slave select.

We want to interface to 4 slaves and the TMS320F28069 only has 2 SPI’s. Can we do this? If so, what is the recommended method?
Here are two methods for you to consider.
Chip-Enabled Multi-Node
Addressed Multi-Node

Changbum,
1./3. The SPI chip select (i.e. SPISTE, CS, CS0, CS1, etc) is a signal that will enable the Slave device to be able to communicate. As the master, the SPI will drive this signal when data is being transmitted. On the slave side, the CS signal…
Hello,
Unfortunately there are no reference designs with multiple SPI devices on the bus.
However, please feel free to look through the following:

Varun,
If you're getting started with F28379D, I would suggest you to make use online worshop training materials which included lab exercises and example projects. It gives a very good overview of various features on this device and its peripherals…
Hi Omer, For some reason Ankit, our customer was unable to upload the files in subject so I'll be uploading the files on his behalf. Piccolo workshop PDF.pdf Module 17 TMDSPREX28335 workshop PDF by Frank Bormann.pdf Kind Regards, Jejomar
Part Number: TMS320F280049 Tool/software: Code Composer Studio Hi
What about the range on the analog inputs for the channels with A/D converters on them of the TI controller TMS320F280049 ? I don't see it in the datasheet.
