What is the meaning of development board ?? |

Hi,
What is the meaning of development board. Is it possible to program the PIC directly from the PC or does the PIC have to be removed and put in a seperate programmer ??
thanks

Many of the "development boards" have the in-circuit serial programming (ICSP) connector on the board and you can program the PIC right on the board. A few even have the entire programmer circuit on the development board.
With the ICSP connector you still have to have an external programmer/interface between the PC and the board like the ICD2 or the ICDU-40 or ICS-40. If you want to buld your own ICSP interface there are a number of them out there to choose from.

I think most people on this forum use a programmer or a boot loader.
So
PC connects to a programmer. ((programmer is ICD2 or CCS_ICD-U40))
programmer connects to target board through the ICD port.
Or
You can re-program a board directly from a PC IF [[IF]] that board has allready been programmed with a boot loader.
To get the ' ' ' FIRST' ' ' boot loader on the PICyou still need a programmer. |

I figured a "development board" is synonymous with a "demo board". They have enough sample circuits on there to fulfill a "proof of concept".
Before the days of ICSP in PICs, your development/demo board obviously didn't have rj11 jacks to program the chip in-circuit. But it was still a development board. |

The meaning of a developemnt board is to charge you a few hundred bucks. |

Hi,
Is it OK to have a development board and not have ICD or ICSP ,and no on board programming ???
thanks

No! I haven't seen a PIC development board, which wouldn't require some kind of programmer. |

Before flash chips and ICSP it was common for development boards to just have the uC in a socket so you could pop it out to erase and program elsewhere. _________________ The search for better is endless. Instead simply find very good and get the job done. |

Actually there are several develoment boards that have embedded bootloaders and do not reuire ICD or ICSP

Back in the pre-ICSP days of OTP and UV erasable PICs (e.g. PIC16C72), they also sold boards to develop code on. What were those boards called? |
