teho Labs – inexpensive LM3S based boards

Procyon

Brian was on our show and tell so we asked him to send along a follow upteho Labs. He writes –

While Arduino gets the lions share of attention in the hobby community there are some limitations to 8-bit microcontrollers which have been recognized by the Arduino project with their recent announcement of plans to make ARM based development boards, as well at the Maple project (STM32 based). ARM microprocessors often offer significantly more RAM/Flash and peripherals at similar prices to traditional 8-bit microcontrollers, however they have a reputation for being harder to use.

In the maker community LPC and STM32 ARM based boards seem the norm, however in my experience LM3S (LM = Luminary Micro which is now owned by Ti) chips are far easier to work with. This is largely due to StellarisWare, which makes peripheral configuration uniform across devices. (See my comparison of UART configuration on many platforms here).

When I realized there were no inexpensive LM3S based boards available (now there are few on eBay as well) I decided to make some. I made a simple breakout style board called Cygni that was as inexpensive as possible so that people could try out ARM and find out that it wasn’t scary after all. And I made two more advanced boards one that could be a USB host (called Eridani) and one that was suitable for tasks requiring a lot of memory, internet access, USB hosting or all of the above (called Procyon).



Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. I also liked the Luminary Micro hardware, but the dev tools was another story. TI’s preferred solution is a Keil solution that runs north of $1K.

    Which tools is he using? (I couldn’t immediately tell from the web site).

  2. Generic GCC + Eclipse/GDB if you want to do JTAG debugging like IAR/Keil etc.

    PS: Being color blind makes that capcha petty hard.

  3. @J.Peterson

    Not true that TI/Luminary prefers Keil (which runs >$2K generally, by the way, as does IAR). When you order a dev/eval kit, you can choose among 4-5 tool chains on CD, but are free to download and use any of them.
