Fresh hacks every day
[Andy] loves his Memotech MTX computer. It’s an oldie with a Z80 running at 4MHz; the perfect target for an FPGA port. The ReMemotech has everything the old one has – cassette interface and all – and can run up to six times faster than the original.
If you’re going … Read the rest
Two months ago we featured a transceiver based on the Microchip MRF49XA, and a lot of feedback was sent to [hpux735] requesting that some brains be added onto the system. [hpux735] decided that if he was going to do it, might as well go the distance and make a make a native USB transceiver.
The prototype model is designed … Read the rest
A couple of weeks ago we put up a post titled Addressing Microchip’s open source problem where we talked about some of their shortcomings as far as open source code goes, specifically the TCP/IP stack and the USB stack. The comments were predictably fairly negative. The interesting part here is that Microchip actually listened. If you read through all of … Read the rest
Hackaday alum and owner of Dangerous Prototypes [Ian Lesnet] recently wrote an editorial piece calling out Microchip on some of their less than friendly attitudes towards open source.
[Ian] and his company use PIC microcontrollers extensively in their projects, and they have quite a high opinion of their products overall. The gripe that he has (and thinks you should have … Read the rest
There are times when you don’t need much processing power for your project but you do need a lot of I/O pins. It often doesn’t make economic sense to choose a larger microcontroller just to get extra pins so the answer is to use a port expander chip. [Raendra] posted a guide for using one of these chips, it’s … Read the rest
If you’ve been hungry for more power for your microcontroller projects, but reluctant to dump your investment in Arduino shields or the libraries and community knowledge that go with them all, Digilent has you covered. Their new chipKIT boards are built around the Microchip PIC32 MCU…a powerful 32-bit chip that until recently was left out of the cross-platform scene. A … Read the rest
We asked for responses to our last Development Board post, and you all followed through. We got comments, forum posts, and emails filled with your opinions. Like last time, there is no way we could cover every board, so here are a few more that seemed to be popular crowd choices. Feel free to keep sending us your favorite … Read the rest
