Hey.. I have been wondering .. i am now the owner of a PicKit 2 and have some Low voltage chips... Would i use a normal ICSP connection to program it? Well how would i connect it since its 3.3v and not 5v
Those are Low voltage chips, not LVP. I've updated the Junebug manual with a 3.3V 24F PIC connection.
In a nutshell if the target PICs have their own power supply and you add the clamp diodes (1N4148 should work with a 3.3v supply) it should work.
Instead of a LM1117 can i use a LM317 and adjust it to 3.3v? Only because i have many on hand and locally is easy to obtain the LM1117 i will of course order but will take like a week or so to get here.
LM317 is fine, you could even use a couple of fresh AA batteries in a pinch. Some folks even use a set of 2 or 3 standard diodes inline with 5V to drop the voltage. Use the unswitched U5V pin if you want your Junebug to supply the 5V.
If you are using a solderless breadboard, there's this product **broken link removed**
It is similar to other breadboard mounted power supplies, but it delivers both 5V and 3.3V. Even if your PIC is 3.3V, you may still have a need for 5V for some of your other components.
