|Phenoptix AVR ISP|
I decided a few days ago that I'd use a Zero Insertion Force (ZIF) socket for the programming. These allow you to drop a chip in, close the gripper of the ZIF, program the chip and then release it. You can then remove the chip easily without any risk of damage.
It's a ZIF socket, Jim, but not as we know itI got a couple of sockets which were surprisingly hard to find in the UK. When they arrived I discovered that they had pins 0.6" apart, rather than the 0.3" that the Phenoptix board expects.
No problem, thought I. I can use a bit of stripboard and add two rows of header pins 0.3" apart, solder in the ZIF socket, and plug the whole thing into the Phenoptix shield.
Today I tried. It won't work, because the pins on the ZIF socket are too short. Even worse, the pins are so short that they won't work reliably in a breadboard.
Plan B - DIY ISP
Luckily I still have plenty of time in hand, so don't worry if you're planning to attend Monday's Shrimping session.
If you are coming to Monday's DiversionRemember:
- Sign up on Monday Morning. We're limited to twenty people.
- Bring a Laptop with WiFi and a spare USB port, and
- Install version 1.0.5 of the Arduino IDE before you come
