TMS320F28335

Hi,

I am looking for schematic examples to program a 28335 with host processor. I would like to use host UART to do this. Have you some hardware examples to be provided ?

Zanzibar,

You can find schematic example in F28335 control card schematics: http://focus.ti.com/docs/toolsw/folders/print/tmdsdock28335.html

In addition to Vamsi's resource, another resource is the TMS320F2833x Reference Design:

http://focus.ti.com/docs/toolsw/folders/print/sprc541.html

Page 6 of the 2833X_REFERENCE.pdf shows the schematic for an RS232 transceiver + RS232 connector port interfaced to the 2833x if this is what you are looking for. Then you can either use SDFlash Serial (downloadable from Spectrum Digital website) or C2000Prog with codeskin (downloadable from codeskin website) to program your device through SCI/UART.

Hello,

The F28335 Experimenter's Kit + F28335 controlCARD provides a communication link via UART, which seems like what you want. You could use this kit to try your communication on. From the Baseline installer from the link below, you could also find schematics, pcb files, and gerber files for each of these boards.

Hello Vamsi,

in the package the schematic for Rel1.2 has a marking "Release 1.1" and release date 4/24/2008, which is identical to Rel 1.1 schematic. Is this a typo or we actually have a wrong schematic diagram?

Also, if they ever update the schematic, just a suggestion. Is it possible to get the schematic diagram in color? It's much easier to read, and can be printed B/W at the user's side.

Arsen,

The marking of "1.1" on the Release 1.2 schematic is a typo. The only difference between revision 1.1 and 1.2 should be a change in X1's oscillator frequency. 30MHz is the recommended value.

You may be able to try editing the coloring, if you wish, by opening the schematic .sch with ExpressPCB and changing it's default color settings. I'm not sure if this would print in color, but it can at least help ease reading the schematic while viewing on the computer.

Thank you,
Brett
