Part Number: TMS570LS0232

Hello Team,

I have a customer who wants to start a new design with Hercules family.
Thier application needs are very simple but the requirement of working temperature range must be -40 up to + 125 degrees.
I found that this family supports desired temperatures and automotive interfaces like CAN and LIN as well.
In addition, there is a requirement of using SD Card when SPI MODE should be more than enough (so far so good).

My questions are:

whether this family is recommending for a new design? I found out this family support was drop out from CSS 7 and examples are limited?

This cause to the customer for a bit concern for lack of examples and support.

additionally, there is a need to add a small LCD display if the device support that?

Can you please advise for the above, Thanks

Best regards,

Shai

Shai,

The TMS570LSx family of MCUs is certainly not NRND, and is actively supported and promoted. Even the latest version of CCS supports these MCUs. They do appear in a class of devices called "Unclassified Devices" for reasons unknown to me. I will certainly find out why this is the case and remedy it.

The TMS570 MCUs do not include an LCD controller/driver though. So these MCUs will have to interface to an external LCD driver IC if that is a mandatory requirement.

Regards,
Sunil

Sunil,

I still find it hard to see where I can download working examples which can be imported to CCS 8 (or there is a limit to use CCS6.2).
I have reviewed the following pages:
processors.wiki.ti.com/.../Category:TMS570
processors.wiki.ti.com/.../Hercules_LaunchPad
Unfortunately, they did not contribute much for me to move forward, the customer is planning to use LAUNCHXL-TMS57004 and I have found it difficult to bring up a working environment can you please assist.
The main use case is to read from ADC and save the captured data on SD Card via SPI Mode.
Do you have any guidance for interfacing with SD Card and if you have any recommendation for LCD driver?
Thanks in advance

Best regards,

Shai

Shai,

The best place to start with examples is HALCoGen. The Help menu in this tool includes several examples with detailed instructions that walk you through each step of the process of configuring the relevant module(s), generating the required driver(s), and accessing the generated code in a CCS project.

I believe we have an example code for accessing an SD card on the HDK via the SPI2 port. It may be in the form of a bootloader, but you can certainly use it as a reference for the SPI communication.

For the LCD driver, as I said the TMS570 MCUs do not include a segmented LCD driver. You can use the SPI or I2C ports to drive an LCD that supports a SPI/I2C interface. See this example: www.ti.com/.../BOOSTXL-K350QVG-S1

Sunil, Thank you I'll look into it.
there is example code of using BOOSTXL-K350QVG-S1 LCD display for the LAUNCHXL-TMS57004?

Shai,
There is example code that runs on the MSP432 launchpad for the www.ti.com/.../BOOSTXL-K350QVG-S1 boosterpack. You can port the code over to TMS570. The porting is not already done.

Shai,

Is there anything else that I can help answer related to this post? Is your customer looking to port the graphics library over to the Hercules MCUs?

I will mark this post as closed and answered. You can post a follow-up questions if any.
