TMS320F28377D: Detailed schematic of the C2000 docking station[R4.1]

Rohan Chawhan

Part Number: TMS320F28377D
Other Parts Discussed in Thread: C2000WARE

I want to serially communicate with an external device via serial port of C2000 microcontroller TMS320F28377D.

// For this example, only init the pins for the SCI-A port.
//  GPIO_SetupPinMux() - Sets the GPxMUX1/2 and GPyMUX1/2 register bits
//  GPIO_SetupPinOptions() - Sets the direction and configuration of the GPIOS
// These functions are found in the F2837xD_Gpio.c file.
//
   GPIO_SetupPinMux(28, GPIO_MUX_CPU1, 1);
   GPIO_SetupPinOptions(28, GPIO_INPUT, GPIO_PUSHPULL);
   GPIO_SetupPinMux(29, GPIO_MUX_CPU1, 1);
   GPIO_SetupPinOptions(29, GPIO_OUTPUT, GPIO_ASYNC);

The above given piece of code should enable GPIO 28 & 29 for serial port.

Issue: I am not having a proper document for the docking station [R4.1] and the pin header outputs coming out of it.

PS - It will be great if a detailed pinout diagram or sheet is available to find different GPOIs separately, different ADC channels etc.

Hi Rohan,

I think you can find the schematics for your board by downloading C2000 Ware and then looking in the following directory:

\ti\c2000\C2000Ware_1_00_01_00\boards\ExperimenterKits

Hi Devin,

Thanks for quick reply.

I found the PDF files in the folder u suggested but they are not that descriptive. Can you tell me where would i find the pin GPIO28 & GPIO29 on docking station. Also how to read this schematic

Attaching a screenshot of my query for your reference.

Hi Rohan,

You can match the above pin number with the pinout mentioned in 180_HSEC8_DV_pinout_R1_1.pdf in the same directory.

Gautam

Hi Gautam,
The PDF you mentioned 180_HSEC8_DV_pinout_R1_1.pdf is again not descriptive.
although i found the required schematics in below location for R1 docking station.
ti\C2000Ware_1_00_01_00\boards\controlCARDs\TMDSCNCD28377D\R1_1

Will you be able to tell me if this same would/should work for R4.1 station as well?

Although it is not communicating with arduino quite well though. with GPIO 28 & 29 (sci).

I am able to communicate with arduino now. I wasn't sending the correct values which gave a garbage output at first. once i sent the ascii values it is showing good output.

That's Great, Rohan!

Goodluck & Regards,
