I've been using the new Code Composer Studio reincarnation for a while now. I like Eclipse, but it shows its age in some corners.

CCS20 is a full redesign based on Theia - with the same fundamentals as VSCode. It's lighter than Eclipse. And just like VSCode, sometimes you 'll need to edit config files to get something done.
Overall experience is positive. This is an easy to use IDE for develop and debug work. Intuitive for VSCode users. Not a steep adoption ramp for CCS Eclipse style users. It took me an evening to get it working. After 2 months, I'm very comfortable.

If you plan to use Code Composer Studio, it's best to skip current version 20.3.x. That version has a defect that it doesn't show errors, and build doesn't complete, if you have syntax errors in your code.

20.2 works.

I'll write a follow up post on advanced debugger use.

The XDS110 can provide board power and has a UART - USB bridge.
There's also a more exciting feature: EnergyTrace:

This is only available from the XDS110 probe. If you use the XDS110 emulator from a LaunchPad, you don't get the energy trace part. The LaunchPads don't have the circuitry for that.

The trace above is the EasyL1105 running in normal power mode. Sending data over UART, receiving some date/ There are no low power modes involved. I'm curious to see if I can manage to trace the behaviour in the lower (and sleep) modes ...

Well done Jan.

Incidentally for anyone wanting this easyL1105 development kit, the steps are easy:

1. Order a PCB using the zipped Gerber files.

2. Order parts using the parts list PDF

3. Build it! Refer to the circuit diagram PDF.

For programming and debugging (e.g. step-by-step debugging, variable content inspection, memory examination): The XDS110 debug tool that Jan is using (super-useful product, works with a huge range of TI microcontrollers), or possibly a TI Launchpad could be repurposed

For programming (no debugging): USB-C cable

The setup works with the GCC ARM Toolchains too. Just tested it for the windows arm cross compiler 14.3:

Build works, and the debug session too. Good news, because the GCC 14.3 has loads of modern C++ goodies.
And the debugger works better. Variables, and hover-over info, are better supported:

In a drive to make PCBs usable with not-so-young eyes any more : ) I was experimenting with the silkscreen text size on the board, I don't know if it's more readable than usual or not. The text size on the pins is 1.2 x 1.5 mm and 0.2 mm thick. The component legends are 1.4 x 1.2 mm and 0.15 mm thick. I believe KiCad default is 1x1 mm and 0.1 mm thickness which is too fine.

To me the text still looks too fine, I will thicken further on any future board. But maybe the font needs consideration too, maybe the KiCad default font isn't the most readable one at small size. I don't know what other people use.

On schematics, I've decided to move to Verdana, it's a lot more readable when printed out.

Hi Jan,

That's more straightforward than I thought it would be. The process seems about as smooth as it possibly could be, and nice to see the debugger just worked!

The SDK that got downloaded contains an example folder, although for different MSPM0 parts, but still interesting to explore. Also it could be maybe worth checking out the SysConfig tool to see how any arbitrary integrated peripherals are configured, since it will generate the C code for that, which can then be inspected and copy-pasted, or the generated files used directly. I've only briefly tried it so far.

I downloaded the standalone version of SysConfig, but I'm guessing it is also embedded in CCStudio), and key tip, is to select "Board". I wasted a very long time not realizing that! : )
