When im using the oshonsoft programmer as a ICP (i think "in circiut prorgammer" that is) is it nessesery or do bootloaders only apply when you are using other typs of programmers?
In order to program the PIC without using a PIC programmer - the bootloader code in the PIC can program itself via a simple serial port connection - which is actually how the ICD2 and PICKit2 programmers work. The PIC actually in the programmer is updated via it's bootloader with the required firmware to program the target device selected.
Well I will try to ask again... Is it nessesary to load a bootloader when using the onshnosoft serial programmer device. As i have made the device allready I dont know wheter to use a bootloader first or if its unnessesary seeing that the programmer dont have a pic or anything like it.
What i have read so far (including om the TinyBootloader page) whith my setup i wont need it. Althou I might be wrong
More or less
You can't directly connect a microcontroller to the serial port, you need a level and logic inverter like the MAX232.
But don't think about bootloaders, you don't need one.
