The LPC810 - an 8-pin DIP ARM processor

LPC810
If you're interested in Electronics you will know that ARM-based chips are found at the heart of many fantastic consumer products: mobile phones, tablets, and of course the Raspberry Pi.

ARM technology has been hackable for a while. I first met the mbed a couple of years back. It's useful, and fun, but what I want now is an ARM board that I've designed and built myself.

Sadly, my ageing eyes and fingers make SMD soldering a challenge. What I need is an ARM processor in DIP format.

And here it is!

nxp actually make two DIP ARM chips. This one is the LP810 - a 32-bit processor in an amazing DIP8 package. Adafruit have a super tutorial on how to breadboard and program it - just what I want.

That promises to be fun, and opens up all sorts of possibilities: imagine stripboard-based projects with a 50MHz 32-bit processor at their heart.

The LCP801 should keep me busy for a while, but I've just ordered its big brother, the LPC1114. That offers
  • 50 MHz
  • 32KB Flash
  • 8KB SRAM
  • SPI
  • I2C
  • USART
  • 10-bit ADC
  • 1×16-bit timer
  • 2×32-bit timers
in a DIP28 package.

Farnell does not carry the DIP version of the LPC1114 but I got a single chip at a reasonable price from a UK seller on eBay. Now I just need to buy some time :)

Farnell does carry the LPC810, which costs an amazing £0.82 + VAT.

Controlling a Raspberry Pi Pico remotely using PySerial

Update : I'm using thie code below in another project, and found that I had not correctly fixed the reported bug. The new version passes automated tests, and I am pretty sure it works OK. I have changed the name of the class to Talker  since it can both send and receive information. Apologies to all concerned for the bug! Introduction You can use a Raspberry Pi Pico as a powerful peripheral to a host - a Raspberry Pi, a Jetson Nano, a laptop or workstation. In this article you'll see how to interact with a Pico running MicroPython or CircuitPython by writing some Python code that runs on the host. The software is easy to use. It enables you to send a Python statement to the Pico and read the results. The statement can be any valid MicroPython code. Setting up the host and the Pico For this article I've used a Raspberry Pi as the host, but any computer running Windows, Linux or Mac OS will do so long as it has Python 3.5 or later installed. In particular, you can use this t...

Five steps to connect Jetson Nano and Arduino

Yesterday's post showed how to link a micro:bit to the Jetson Nano. One of the members of the (unofficial) NVIDIA Jetson Nano group on Facebook asked about connecting an Arduino to the Jetson. Here's a simple recipe for getting data from the Arduino to the Jetson Nano. It should work on all the Jetson models, not just the Nano, but I only have Nanos to hand. On request, I've added a recipe at the end of this post which sends data from the Jetson Nano to the Arduino; it turns the default LED on the Arduino on or off. The recipe for sending data from the Arduino to the Jetson has just 5 stages: Program the Arduino. (I used the ASCIITable example). Connect the Arduino to the Jetson using a USB connector Install pyserial on the Jetson Download a three-line Python script Run the script.   Programming the Arduino I used an Arduino Uno, and checked it on a verteran Duemilanove (above), but any Arduino should work. You'll need to do this step usi...

Raspberry Pi Pico project 2 - MCP3008

This post show you how to drive the MCP3008 8-channel ADC using a Raspberry Pi Pico. I'll start with a personally embarrassing and annoyingly relevant story. I'll also tell you about a minor 'gotcha' when using SPI on the Pico, and how you can avoid it. Finally, I've include the code and fritzing diagram I used to test the interface. First, the story. Back in 2012, when the Raspberry Pi was fresh and new, I was running a startup called Quick2Wire.  We made add-on boards for the Pi. Just before Christmas we sent out our first batch of boards to a small army of beta-testers. The beta boards didn't work. Somehow a single trace on the pcb had got deleted and one of the GPIO pins was isolated. The boards were still usable and it wasn't too hard to solder in a jumper wire to replace the missing trace, but it was very embarrassing. It wasn't just that we'd shipped boards with a defect. The really annoying thing was that I'd set up an  automated loop-bac...
