Re: NRF24L01

Peak transmitter current is probably more than a 9V battery can supply.

Re: PIC Microcontroller

Just design a suitable PCB and get it made. Program the PIC with a PICkit 3 or ICD 3.

Re: Unable to Program the simplest function on PIC12f509

The posted code is the output from the assembler, which won't compile. You need to assemble the source code. Try assembling this using MPLAB IDE 8.93: ;test.asm #include <p12F508.inc> org 0 nop movlw 0 tris GPIO ;all GP pins set to output loop: movlw b'000010' ;toggle GP1 movwf GPIO movlw b'000000' ...

Re: how to design a pcb for manufacturing

Here are the ITEAD Studio requirements for PCBs they supply:

They are quite typical.

I have my PCB package (Pulsonix) set up for various board suppliers, which saves a lot of time.

Re: PCB house

FWIW, ITead and Seeed both use the same PCB manufacturer. ITead appears to be faster for delivery.

Re: nRF24L01+ does not work

First thing to check is that you are actually communicating with the nRF24L01+ registers.

Re: AVR Programmer query

It depends on the target board. Those different kits have different cables/connectors.

Re: AVR Programmer query

One that also supports debugging would be a good idea, like the Atmel AVR Dragon or the Atmel-ICE.
