Chris Holden of NerdClub shares his tips on how he successfully program an ATMega128:
Finally got an ATMega128 chip coded and programmed successfully. The great news is it doesn’t require Arduino. The even better news is, we can use Oshonsoft to write the code! Yay.

There are a lot of little details you need to think about when taking a project from PoC (proof-of-concept) to production. Most projects today have some form of onboard microprocessor and require you to flash your custom bootloader and/or program code onto it at some point. There are many ways this can be accomplished but the most common method is using an ICP (in-circuit programmer) connected to a 6-pin ICP header somewhere on the PCB. [...]
Tag-Connect! I can’t remember exactly how I found out about this neat little connector, but I’ve been using it for a while and it’s actually very useful in a production environment. They provide the footprint for many of the popular PCB design programs so placing it is very straight forward. Pretty much just swap out the traditional header for the new tiny Tag-Connect version and you’re pretty much done.

Here is a very nice graph showing the most popular programming Languages of 2014.
Every year we release data on the “Most Popular Programming Languages” based on thousands of data points we’ve collected by processing over 100,000+ coding tests and challenges by over 2,000+ employers.
This gives us a pretty good idea on what the trends are for the upcoming year in terms of what companies are looking for. It’s data we hope will be especially helpful for new computer sciences graduates or coders looking to stay ahead of the curve.

Programming microcontrollers isn’t hard. Building a programmer makes a great first electronics project. The goal of this instructable is to explain the simple ‘in circuit serial programming’ method used with Microchip PICs.

Some key features:
- Supports all programmers and MCUs that AVRDUDE supports
- Supports presets, allowing you to change between devices and configurations quickly and easily
- Drag and drop files for easy uploading
- Automatically lists available COM ports

Picked up one of these IC test clips on eBay for a few quid.
The idea is that you clip it to a chip on a circuit board so you have easy access to the connections for use with test probes.
I’ve got a different use for it though. If you develop a circuit using an Atmega chip (like, say, a circuit you developed with an Arduino but have now moved to a custom board), reprogramming the chip is fiddly. The best way to make your circuit easily re-programmable is to build an ISP header onto your board – it’s just a 6-pin connector that lets you blast new programming onto the chip without removing it from the circuit.
