Fresh hacks every day
[Andrzej Surowiec] liked the functionality of the mass storage bootloader available on some NXP LPC development boards. His latest project was to write a mass storage bootloader for the Stellaris Launchpad. It allows you to flash your compiled firmware to the chip simply by mounting the board as a USB storage device and copying over the binary file. The chip has plenty of flash memory (the … [Read more...]
On the continuing list of homebrew ARM dev boards we've seen over the past few months, [Squonk42]'s USBug is one of the best we've seen. Like many other ARM boards, it breaks out a member of the Cortex M0/M3 family into a 40-pin DIP, but unlike all the others, [Squonk] designed it so you can drag and drop code onto the microcontroller just like a USB thumb drive. [Squonk]'s trick relies on a … [Read more...]
A few weeks ago, we saw codebender, an online replacement for the Arduino IDE that allowed you to upload a sketch to your board from a web browser. Over on the codebender blog [Vasilis] and his team are rolling out a way to remotely upload code to an Arduino over Ethernet. Now you don't even need a serial connection to program an Arduino; it can be done over the Internet to a board in the next … [Read more...]
Here's a way to program an Arduino wirelessly while still using the stock IDE. It uses an alternative bootloader called SuperDuplex along with an IR receiver like the ones used for TV remotes. As you can see, this does take two parts. There is the target device which has the IR receiver, as well as the transmitting unit which connects to the computer via USB. You can see a demonstration of the … [Read more...]
[Joby Taffey] just rolled out a serial bootloader for the Chipcon CC1110/CC1111 processors. The project is called CCTL and aims to make prototyping with the Girltech IM-ME a bit less tedious. Up until now firmware for the device had to be pushed in with a GoodFET or TI proprietary programmer which was quite slow. But this bootloader makes it possible to push your code via the chip's serial port … [Read more...]
[Fezoj] likes to play around with microcontrollers and decided that he wanted to try a Bus Pirate as a new tool in his adventures. Since it's open hardware he had his own board made and populated it himself. The trouble is, he works only with AVR chips and doesn't have a PIC programmer. No problem, he figured out how to flash the PIC24FJ using an ATmega8. To get started, he grabbed a copy of … [Read more...]
The weekend is almost here and if you're looking for an afternoon project consider building your own binary wall clock. [Emihackr97] built the one you see above using parts on hand, but even if you put in an order for everything, it won't cost you much. He used a cardboard box as the housing for the clock, marking a grid for the LEDs on the face and drilling holes to house them. Two columns for … [Read more...]
