TLC6C5716-Q1: Need Sample code for TLC6C5716-Q1

Sumit Kumar

Part Number: TLC6C5716-Q1

Hi Team,

I am working on TLC6C5716-Q1 communication to micro via SPI. Is there any reference guide/ sample code/ fit data documents available to Kick start the project.

Hi Simit,

You could refer to this:

TLC6C5716-Q1 EVM Programming.pptx

Hi Gracie,
Sorry for the late reply i was on vacation and thanks for the support.
i am not able to relate page 3 and 4 of the ppt you have shared. can you please help me out bit more on it.

Hi Sumit,

It's just the procedure of starting this LED driver. You may refer to the datasheet to see each command and that should be matching the log detail in page 4.

Hi Gracie,
Thanks for the sample code, but i am not getting how the LEDs are being controlled using these two functions. Please brief it, it will be very helpful.

0 Gracie Guo over 1 year ago in reply to Sumit Kumar

TI__Genius 15496 points

Hi Sumit,

What's your application of this device? The end equipment? one or daisy chain?

And could you elaborate which 2 functions?

This LED driver is a sires interface, common shift register to transfer the brightness (GS data) and store the control data.

BR, Gracie

0 Sumit Kumar over 1 year ago in reply to Gracie Guo

Prodigy 40 points

Hi Gracie,
the 2 function i am talking about is the SendDCData() & SendGSData().

The end equipment is, i have a Microcontroller which is connected to only one TLC6C5716-Q1 via SPI to control 10 LEDs.

Hi, Sumit

Our expert is out of office and will reply you on Thursday.

0 Gracie Guo over 1 year ago in reply to Sumit Kumar

TI__Genius 15496 points

Hi Sumit,

Basically you need to send DC data to the corresponding location

You can see at start, you need to configure to low 205-bit FC-BC-DC Data in the 288-bit shift register. It's the initial setting. And then you can send GS data to refresh the brightness.

Hi Gracie,

Thanks for your continuous support, please clarify one last question.

Q1. //Send DC/BC/FC data thru GS Data Path............ you can find this comment at line no. 104 of the software you have provided. what does GS data path mean, is it sending data thru SendGSData() function? according to my understanding we software is sending FC BC DC data thru SendDCData().

Q2. In function SendDCData() how to set the values of these arguments "char DC_Range_Blue, char DC_Range_Green, char DC_Range_Red, char BCB, char BCG, char BCR," please let me know where can i find it i am using TLC6C5716-Q1 Automotive 16-Channel, Full Diagnostics, Constant-Current LED Driver document for reference.

Thanks,

Sumit

Hi Sumit,

Sorry for replying late. I was on sick leave..

I didn't see any conflicts here.

GS_mode is defined in sendDCdata() because GS_mode could be selected 8/10/12 bit for the resolution.

The GS data is in sendGSdtata.

BR, Gracie
