CCS/TMS320F28027: Guide me through how to use piccolo micro controller I'm very new to this

Nikhil,

To learn about the F28027 device, you might want to start by running the lab exercises in the F28027 one-day workshop:

processors.wiki.ti.com/.../C2000_Archived_Workshops

Run the Piccolo One-Day Workshop Installer to set up the workshop files. This workshop was developed with an obsolete kit (controlSTICK) and you are most likely using the F28027 LaunchPad. Additionally, this workshop was developed with CCSv4. However, using a newer version of CCS will work but the lab directions may need to be slightly modified.

In the workshop an LED is toggled as a visual indicator. The LED is connected to a different GPIO pin on the LaunchPad (compared to the controlSTICK). You will need to make a minor modification to the code to have the LED blink. To use GPIO1 to blink the LED, please make the following changes to the Lab 3 and 4 files:

In Gpio.c modify the following two lines at the bottom of the file (note GPA for group A, so change ...GPB... to ...GPA...):

//--- Selected pin configurations
GpioCtrlRegs.GPADIR.bit.GPIO1 = 1;
GpioDataRegs.GPASET.bit.GPIO1 = 1;

Next, in DefaultIsr_3_4 modify the following code lines in the ADC_INT1 ISR at line 168 :

static volatile Uint16 GPIO1_count = 0; // Counter for pin toggle

And the following code lines starting at line 193 (again note ...GPA... and not ...GPB...):

if(GPIO1_count++ > 25000) // Toggle slowly to see the LED blink
{
GpioDataRegs.GPATOGGLE.bit.GPIO1 = 1; // Toggle the pin
GPIO1_count = 0; // Reset the counter
}

I hope this helps. If this answers your question, please click the green "Verified Answer" button. Thanks.

Thank you for replying it helped me to get start with this MC, can you guide me throught to How to program to drive mosfets of buck and boost in converter circuit at 200Khz also How can I program to measure input current, output current, input voltage, output voltage of the converter circuit through diffeereent ADC pins?

Nikhil,

This is a good starting point

Also on the same page Ken pointed to you , we have a 1 day workshop material that steps you through some of the aspects you are looking at.

Also, if you are starting to learn and there is no business reason to use F28027 ,

I will recommend using the latest F2804x or F2807x type of platform to learn. The archived workshop does not use this new device, so you should use that one only for the F2803x/2x training.

You can refer to the BOOSTXL-BUCKCONV to understand digital power code on the new devices such as F2807x and F28069 etc.

Help me with the code, where can I foun dthe code for this?

Nikhil,

I understand i have provided an appropriate answer to your question and have not heard back for more than 2 weeks.

I will have to close this thread, please post any further questions on a new thread.

if you strongly feel the above did not help, please clarify.
