Version 1.6.4 of the Arduino IDE has been out for a little while now, and it has a couple of notable changes. To our eyes, the most interesting change makes adding support for non-standard boards and their configurations within the Arduino IDE a lot simpler. We’ll get into details below.
Now on to the meat of this post. The new “Board Manager” functionality makes it significantly easier for other non-Arduino products to be programmed within the Arduino IDE. Adafruit has a tutorial on using the Board Manager functionality with their products, and it basically boils down to “enter the right URL, click on the boards you want, download, restart Arduino, bam!”
The list of unofficially supported third-party boards is still a bit short, but it includes some stellar entries. For instance, Adafruit has provided the files needed for the ESP8266, which recently received the Arduino treatment. This means that you can simply point your IDE at Adafruit’s URL, and it’ll set you up with everything needed to develop for the ESP8266 from within the comfy Arduino IDE.
We keep wondering where the Arduino world is headed with the hardware getting more and more powerful. If the IDE doesn’t keep up what’s the point? Now we have at least one answer to that problem. Energia is the Arduino-like-framework for Texas Instruments based boards. They just came out with a multitasking system built into Energia targeted at the ARM Cortex-M4F based MSP432 Launchpad which we covered a few weeks back.
The announcement post gives a couple of examples of uses for multitasking. The simplest is blinking LEDs at different rates. If you wanted to do this closer to the metal you’re talking about multiple timers, or multiple compares on a single timer, perhaps a interrupt-driven-system-tick that has a high enough resolution for a wide range of your blinking needs. But these are not always easy to set up unless you are intimately comfortable with this particular architecture. The Energia multitasking will handle this for you. It’s upon the TI Real Time Operating System (TI-RTOS) but wraped in the familiar IDE.
The UI divorces you from thinking about the hardware at all. You simply launch a new tab and start coding as if you’re using a completely separate piece of hardware. The announcement post linked above mentions that these Sketches are running “in parallel”. Well… we know it’s not a multi-core system like the Propeller but we’ll let it slide. It is certainly easier than building your own scheduler for this type of hardware.
A long time ago, [Martin] played with old 8-bit computers. Recently, he’s been honing his assembly skills again, and the idea of an IDE for a boatload of old systems came to him. After a year of work, he announced a multitarget IDE for 8-bit computers that works in your browser.
The project is called ASM80, and includes a code editor, a workspace to put all your code, compilers for the 8080/8085, Z80, 6502, 6800 and 6809 CPUs, emulators for all these CPUs, and emulators for a few Czech computers, the ZX Spectrum, and a few of [Grant Searle]’s single board computers.
What makes this project interesting is the syntax for all the different CPUs is pretty much the same. It’s a real, modular code editor that supports macros and everything you would expect for a code editor for ancient computers.
If you’re looking to connect things to the internet, with the goal of building some sort of “Internet of Things,” the new CC3200 chip from TI is an interesting option. Now you can get started quickly with the Energia development environment for the CC3200.
We discussed the CC3200 previously on Hackaday. The chip gives you an ARM Cortex M4 processor with a built-in WiFi stack and radio. It supports things like web servers and SSL out of the box.
Energia is an Arduino-like development environment for TI chips. It makes writing firmware for these devices easier, since a lot of the work is already done. The collection of libraries aids in getting prototypes running quickly. You can even debug Energia sketches using TI’s fully featured IDE.
With this new release of Energia, the existing Energia WiFi library supports the built-in WiFi radio on the CC3200. This should make prototyping of WiFi devices easier, and cheaper since the CC3200 Launchpad retails for $30.
With The Hackaday Prize, you’re not just limited to one entry. Of course it would be better to devote your time and efforts to only one project if you’re competing for a trip to space, but if you’re [Necromant], you might be working on two highly related project that are both good enough for The Hackaday Prize
[Necromant]’s first project is rf24boot, an over-the-air bootloader using the very cheap and very popular NRF24L01 2.4GHz wireless module. There have been many, many projects that add wireless bootloading to microcontrollers using XBees and the NRF24, but [Necromant] is doing something different with this project: he’s building in support for a wide variety of microcontrollers, that include the STM32, MSP430, PIC32, 8051, and of course AVR chips for that ever so popular Arduino compatibility.
The support of multiple microcontroller platforms is a result of [Necromant]’s other entry to The Hackaday Prize, Antares, the Linux kernel-like build system for microcontrollers. The idea behind Antares is to separate the writing of code from microcontrollers away from compiling and burning. Think of it as a giant makefile on steroids that works with everything, that also includes a few libraries for common projects.
Supported platforms for Antares include the popular aforementioned targets, and allow you to use any IDE you could possibly desire. emacs? Sure. Eclipse? Right on. Arduino? You’re a masochist. For a really great overview of Antares you can check out the Readme, or the post we did a year or so ago.
It’s all very cool stuff, and very easy to see the potential of what [Necromant]’s working on. Combining the two together, it’s almost a complete system for developing that Internet of Things we’ve been hearing about – uploading code to simple AVRs for simple sensors, and deploying significantly more complex code for your ARM-powered dishwasher or microwave.
Ever since I received my PSOC 4 Pioneer kit from Cypress I have wanted to play with this little mixed-signal Programmable System-on-Chip (PSOC) developer board. I love developer boards, providing that they are priced in a way to entice me to not only open my wallet but also make time in a busy schedule. I think my kit was free after winning a swag bag from Adafruit that they themselves obtained at the Open Hardware Summit and gave away on their weekly streamcast. Ultimately it was the invitation to beta test datasheet.net which also was included in that pile of swag that led to my getting involved with Hackaday.
What is Programmable System On Chip?
So what is a PSOC 4? A quick summary is that it’s based on an ARM Cortex reduced instruction set processor (RISC) and is somewhat capable of supporting shields based on the Arduino footprint, and it also uses a bright red PCB that I have come to associate with a Sparkfun PCB. What doesn’t show is the fact that this programmable system on chip has programmable analog function blocks in addition to programmable digital logic blocks. There is also some supporting input/output circuitry such as a multicolored LED and a capacitive touch sensor directly on the PCB.
This is an intriguing amount of programmability, so much so that Newark/Element 14 highlighted a “100 projects in 100 days” event on it.
Enter the IDE
Over the years I have had to create or install many Integrated Development Environments (IDE) that linked hardware to software. Knowing that you had to, and how to, implement an IDE was part of being an engineer. Nowadays with the Arduino type environment the user has an IDE pretty much as soon as they click on the executable which I find to be one of the best aspects of the genre. It was so quick in fact that I was able to get my teenaged son into writing his first program even before he remembered to do massive eye-rolls and make sounds of utter disdain. He did give up however, just shy of learning how to have the Arduino make sounds of disdain on his behalf.
