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:
Now comparing with the previous launchpads LAUNCHX-F28069M & LAUNCHXL-F28027/F
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
2) ADCIN14 (Pin 23) when connected to 3.3V ie J1 Pin no.1 : RED LED Turns ON
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)
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
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to david zhang2:
david zhang2I 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
Math blocks : C:\ti\controlSUITE\libs\app_libs\motor_control\math_blocks
something that really catches my attention about this new MCU, is your name " C2000 Delfino" ?, why designers will put this name so quirky!!
In reply to Martin Valencia:
Martin, C2000 mcus are divided in to sub-classes:
and F28377S falls under Delfino family.
Check this link:
Delfino is Italian for Dolphin. These are our C2000 performance devices; they are fast and smart like a Dolphin. :)
