Kickstarter and LPLC PIC18 development board

It looks like this is a good time of year for Kickstarter projects to turn up. Not only did I receive my MoPi board yesterday, but today I got three of Mike Hibbett’s LPLC PIC18 development board in the post. I must admit that I am a complete newbie when it comes to PIC development. …

MoPi has arrived

A pleasant surprise today – I received two packages. One was a bunch of stuff from Cool Components, who are having a summer sale for just a few days, and had tempted me to spend more cash. I’ll work through those bits another time. The smaller, but potentially more interesting package was the MoPi board …

A new meeting place for the Ipswich Makerspace

Yesterday I went along to another meeting of the Ipswich Makerspace. This time we were in a larger hall at Holy Trinity Church, just across from the small room we met in last time. We had a few more people turn up, but there’s still plenty of room to grow! This week we had a …

Dangerous Prototypes bench power supply

Generic PC components are astonishingly cheap, due mainly to economies of scale and the continuing demand for the newest and greatest. This gives a lot of opportunities for anyone with an interest in tinkering. Take for example the PC power supply unit. Since the introduction of the ATX connection standard about 20 years ago, pretty …

Arduino serial communication finally working

After several attempts ( blogged here, here, and here ) at getting an Atmel AVR chip on a daughter board to communicate with a Raspberry Pi, I am now excited to report that I have it working. I turned out here were several things wrong: I needed to stop the Raspberry Pi serial port console …

Using a timer interrupt with KDS and K64F

Another demo that I saw while at the Freescale Tech Day was also pretty simple, but already moving a step beyond the traditional Arduino examples. It’s just blinking a LED, but rather than the “brute force” approach of switching the pin then forcing a wait before switching it again (the algorithm in the classic Arduino …

An inspiring day at Reading University

Yesterday I drove my daughter over to Reading for a university open day. Even though it feels as though she has just started A-levels, it’s time to think about what happens after sixth-form. Things kicked off at the university at 09:30, so we left a little before 07:00 to drive the 130 miles or so. …

More serial port foolishness

So I’m still banging my head against the difficulty of making a simple serial connection between my Raspberry Pi and an ATMega chip on a daughter board. And I still have not got it working properly. Overnight it occurred to me that I ought to have turned off the serial port login on the Raspberry …

A first project with FRDM-K64F and Kinetis Design Studio

Today, I thought I’d have a go at running one of the simple demonstrations I saw at the recent Freescale Tech Day in Milton Keynes. I have a FRDM-K64F development board which I bought a few weeks ago, and my fresh installation of the KDS IDE. The K64F is a lovely board with a powerful …

Freescale Tech Day in Milton Keynes

No post yesterday, as I was attending a “Designing with Freescale” Tech Day. If you have been reading this blog for a while, you will probably know that I like working with Freescale ARM microcontrollers, particularly with their low cost and surprisingly powerful FRDM range of development boards. For once, I had a day where …
