Hello Everyone,

Here’s the most powerful and compact C2000 launchpad “LAUNCHXL-F28377S” which is equipped with TMS320F28377S Delfino Controller. Received the kit couple of days back and I’m back with a quick hands-on as usual.

Previous Hands-on LAUNCHXL-F28069M:

Box Contents:

Now comparing with the previous launchpads LAUNCHX-F28069M & LAUNCHXL-F28027/F

FASTEST @ 200 MHz compared to 90MHz (LAUNCHX-F28069M) & 60MHz (LAUNCHXL-F28027/F).
16-Bit ADC as compared to 12-bit in previous launchpads
Additional peripherals like DACs, EMIF, DMA, McBSP, uPP that were absent in previous ones.
Has CLA, TMU & VCU II accelerators
Finally more memory (RAM & Flash)

First-time connection with PC:

The moment F28377S based launchpad is connected to PC, respective drivers get installed and a Virtual COM Port is assigned. This COM Port value can be verified by navigating to device manager:

In my case, BeagleBone USB Serial Port (COM49)

Running the Out-of-box demo:

This demo demonstrates the ADC sampling phenomenon by comparing the digital values with the mid-scale value (2048) to blink the respective LED (red or blue).

In short, if ADC value is less than 2048 : blue led would glow else if greater, then red led would glow. You can monitor the digital values on terminal application using COM Port.

I used Hyperterminal for monitoring digital values.

1) ADCIN14 (Pin 23) when left open ie floating or grounded: BLUE LED Turns ON

On Hyperterminal

Floating:

2. Grounded:

2) ADCIN14 (Pin 23) when connected to 3.3V ie J1 Pin no.1 : RED LED Turns ON

On Hyperterminal:

Conclusion and my quick thought on the launchpad:

By launching this kit, C2000 family is now well equipped with launchpads meant for basic to advanced applications covering real-time control applications such as motor control, digital power supplies, solar and renewable energy, LED lighting, smart grid, radar and more…

With LAUNCHXL-F28377S one can feel the power of Delfino mcu group with 5ns CPU cycle time!

Note: Don't forget to update your controlSuite for the board design files and out-of-box source code.

DUAL-SCI Communication with LAUNCHXL-F28377S Launchpad

SCI Communication with:

1. PC (SCI-A)

2. Serial LCD (SCI-B)

Posting an interactive C2000 Encyclopedia (With some information on C2000, Delfino, F28377S and above launchpad)

Description:

So what I'm doing here is:

a. Accept an input from user on which he/she is looking info on -> through LCD and GPIO interface.

b. Once the input is received -> the information on that topic is displayed on the terminal application in PC.

As simple as that :)

Let me share you my setup:

Let me give you technical details:

Button 1 : GPIO14 (J4:38)

Button 2 : GPIO15 (J4:37)

Button 3 : GPIO16 (J4:36)

Button 4 : GPIO17 (J4:35)

Enter Button : GPIO12 (J4:40)

Instead of button I'm using an open ended plug-in cable that is connected to 3.3V and the logic is that GPIO 14,15,16,17 are configured as inputs and as soon as I make a contact with 3.3V cable I can notice the toggling by reading their respective GPADAT register.

Here's the open-ended plug-n cable I'm talking about:

Now about the SCI configuration:

1. SCI-A connected to GPIO84 (SCITXDA) & GPIO85 (SCIRXDA) through FTDI chip ie Virtual COM Port.

2. SCI-B connected to GPIO10 (SCITXDA) & GPIO11 (SCIRXDA) through a level shifter circuitry to Serial LCD.

I'm attaching a video for everyone to understand how all this works:

Also, here's the out file for you guys to try out: Dual_SCI_F28377S_GGI.zip

I just bought LAUNCHXL-F28377S and BOOSTXL-DRV8301 (TI conbined two boards as a bundle), but I can't find example project (motor control) for these boards.
Does any one know how to get the code?

Chris Clearman would you like to take this?

David you should be able to use the motor library: C:\ti\controlSUITE\libs\app_libs\motor_control

and drivers meant for F28335 (ie defino floating point) : C:\ti\controlSUITE\libs\app_libs\motor_control\drivers\f2833x_v2.0

something that really catches my attention about this new MCU, is your name " C2000 Delfino" ?, why designers will put this name so quirky!!

Gautam Iyer over 9 years ago in reply to Martin Valencia

Guru 192875 points

Martin, C2000 mcus are divided in to sub-classes:

1. Piccolo

2. Delfino

3. Concerto

4. Instaspin

and F28377S falls under Delfino family.

Hi,

When will the F28277S processors be available? I can't find them at distributors and the TI web site shows them as backordered (for the 100 pin package) and "Preview" for the BGA packages. In particular I need to have a prototype up and running by December, will the 100 pin packages be off backorder and available before then?

These processors look great, even better than the 335 which I've been previously using. I just purchased a Launchpad to get started for now.

Thanks for your help,

Mike

Hi Mike,

We are in the process of transitioning to the final production silicon which will begin sampling at the end of Oct. We should be able to support TMX samples in the next few weeks before the production silicon is available. Also in the meantime you could easily begin development with either the F2837xD or the F2807x. These variants are pin and software compatible so if you can easily migrate from either of these devices to the F2837xS once it's available.

Hi!

i just purchased the delfino launchpad , i tried this tutorial:

i cant understand from where he takes the code example ?

please advise me if you can

it seems that the example in Ken Schachter's video , and the launchpad demo provided in the controlsuitear are different ,

what do i missing?

Ken's tutorial he walks through is different from the example in controlSUITE which Gautam shows. To follow Gautam's video, use the code in controlSUITE.

Hi Gautam,

Great post. I received my LAUNCHXL-F28377S a few weeks ago. Just FYI the COM port enumerates in Device Manager on my PC (Windows 8.1) as "USB Serial Port (COMxx)" (xx is 19 on my PC), not "Beagle Bone USB Serial Port (COMxx)". Maybe they made a change. But I don't see how since the FTDI USB to Serial chip is being used, along with it's driver.

Anyway, to my question: Out of the box it communicated at 115,200 baud. After playing around and loading other code, I reloaded the original code, "F28377S LaunchPad Out of Box Demo" project, "Example_28377SLaunchPad". Now it communicates at 57,600 baud, half the 115,200.. (Initially I got garbage, so I changed the baud rate to discover this.) Is the code supplied in ControlSuite possibly running at one-half the clock frequency? My code's release date is July 15, 2015. Is that the latest? Do you know where this is done in the code?

Thanks,

Gautam Iyer over 8 years ago in reply to Edward Schwartz

Guru 192875 points

I'm not aware of the latest software change in controlSuite. But my suggestion would be to play with the baudrate or clock.
Either of the modifications would help you achieve the communication.

Edward Schwartz over 8 years ago in reply to Vivek Singh

Intellectual 880 points

Thanks. I knew it had to be something like this. I looked briefly at the code but it wasn't immediately obvious where in the code it was, so I thought it would be more efficient for me to ask on the forum. (This is a great time saver!)

Is this the correct thread, or should I have posted on the C2000 general forum?

Also, I'm not seeing the green "Verify Answer" button (I used it the other day in another post). Do you know where it is?

Thread is currently set as a discussion thread which leaves off the verify and suggested answer buttons.

Gautam Iyer - Feel free to flip it to Q&A thread type if it makes sense to change so that verify/suggested buttons are available on this thread.

Edward Schwartz over 8 years ago in reply to Gautam Iyer

Intellectual 880 points

Thanks. Mr. Singh also linked to this bug. Doubling the main clock (from 100 to 200 MHz) might have repercussions elsewhere. I see from the Tech Ref Manual, "The internally-generated serial clock is determined by the low speed peripheral clock (LSPCLK)", so I'll check where else that's used, etc. I imagine these things will be (should be) controlled either by #defines or variables, so all the registers affected are automatically set correctly whenever the main clock is changed. At least that's what I do in my code when I need to have a few different clock frequencies for different product variations.

I'm really having fun analyzing the code! It's much more advanced than, for instance, the example code for CCE3 and CCS5.5 for the MSP430 family I'm coming from. There's quite a bit to learn about this chip in addition to the new syntax for register structures (which should help greatly when porting code to other chips).

Thanks for sharing. I got this a few months back. My biggest problem, is the exposed pwm channels. Why not have 6 contiguous pwm available? It is not enough to control a motor without complicating the external circuits.

Gautam Iyer over 8 years ago in reply to Leong

Guru 192875 points

Your requirement is 6 ePWM modules available with both A & B channels? Do check the schematic of the launchpad present here:

my original idea was to use this as a daughter board sitting on a interface board with simple routing and connectors to control a three phase inverter.. but without complimentary pwms the dead time has to be generated elsewhere.. which defeats the purpose of a simple board..

Hi Gautam,

A quick glance at the TRM of F28377S makes me think that F28377S is a F28075 clocked at 200 MHz with more memory. Then why is it a Delfino? What is the major difference?

ChrisClearman over 8 years ago in reply to Prakash Kumar Thulasi Kumar

TI__Guru** 118320 points

actually the inverse:

The F28075 appears to be a F28377S clocked at 120 MHz, why is it a Piccolo?

is a better way to frame it.

The C2000 family is split into

Delfino - high performance, higher memories, larger pin-outs

Piccolo - low-mid performance, smaller memories, smaller pin-out

The F28075 straddles between the two, but for marketing reasons we decided to name it a Piccolo device.
