It's all about speed...


Early in development, someone asked me how fast Swift for Arduino was, compared to the standard IDE.

I recently did a speed test and the answer is... "fast"!

On this speed test it's 10% faster.  The test was simple, digitalWrite on then off, on off, on off, etc. 8 times, then measure the results with a Saleae logic analyser.

Here's the test running on a classic Arduino IDE...


And now on Swift for Arduino...


... this, on a plain, unmodified, out of the box Arduino UNO, in a simple test and using the standard pin functions for flipping pins, Swift For Arduino took 3.8us (3.8 microseconds) and the classic Arduino IDE took 4.2us (4.2 microseconds). Without any modification, without any tricks and on a normal test, Swift for Arduino, writing using Swift code is 10% faster than the standard Arduino IDE using C code. We are very pleased with the results! ðŸ˜€


UPDATE: Tested on version 4.0 of Swift for Arduino, this is even faster! It now flips pins in 3.5us, which is 20% faster than the Arduino IDE version.

Halloween LED lights on a plastic trick or treat cauldron

Image
Halloween has past but it wasn’t uneventful. My two year old daughter went trick or treating for the first time and it was all so exciting! When i saw the plastic cauldron she was carrying as a trick or treat bag i had an idea. I could use an arduino to operate red LEDs and make the cauldron flash on and off like little evil eyes. I knew she would love it! Once I drilled the holes and got all the pieces I needed: 2 red LEDs soldered in series with a resistor. I connected those to a breadboard arduino I had spare. (See my blog post on making a breadboard arduino.) You can just use a normal Arduino UNO here instead if you prefer. My reasons are because they're cheaper, and also because a breadboard Arduino uses less power and I wanted this to be battery powered. I'm powering the whole thing with 3 AA batteries in a battery case. Because Maplin has shut down in the UK :((( I will have to wait for the battery holder to be delivered... no more weekend fun popping down t

All about bootloaders

 BOOTLOADERS *** Some interesting general boot loader facts: The Boot Loader is basically a section at the top of flash memory, how big it is depends on the BOOTSZ1 and BOOTSZ0 bits in the Low Fuse byte. It has the special property that ONLY while the core is running instructions in the bootloader, a special instruction called SPM will function. This function allows writing data to the flash memory. As normal with all flash, you need to erase the page you are writing first, otherwise your write operation will often not function correctly. I think you can change 1 bits to 0 bits but not the other way around, which is true for all flash writing. So the flash erase process always sets a flash memory page to all 0xFF (all 1 bits) The usual way the boot loader runs is if the fuse bit BOOTRST is active (i.e. it reads as a 0!) then when the MCU is reset, it will start execution at the beginning of the bootloader (as defined above). If the bit is not set, it will start execution at 0x0000. But

Pushing the limits

 The nice thing about Swift for Arduino these days is we are having a lot of conversations like "exactly how much performance can you get from an atmega328p, how much program space is the limit? what about RAM?" To me it shows we've gone far beyond the 'hobbyist' place we started from and now as we build professional products, we are dealing with the same issues all professional embedded developers grapple with... in a word efficiency. To that end I thought it might be worth me putting down some thoughts on what some of the numbers are, where the overheads are, what are the limits on RAM and program memory? I'm talking here to the atmega328p as that's what most of our work uses.. the classic Arduino UNO heart, but of course similar things would apply for other chips. In spec, we have 2k RAM, 32k program memory? Can I use all of those? Of course not. ;-) Let's break it down. PROGRAM MEMORY You might have seen my earlier article with a breakdown of what
