To program a pic18f4550 you simply have to connect pin mclr to pin 1 of the pickit3,
pin pgd to pin 4 of the pickit 3
pin pgc to pin 5 of the pickit 3
then from vdd and vss connect to a +5v source, and connect this source +5v to pin 2 of the pickit3 and 0gnd to pin 3 of the pickit3
Then simply...
I have a pickit3, and I've been programming a dspic30f4011.
I used the sample code from the back of the programming guide.(I'm using the C30 library)
I have a 10k resistor from Vdd to MCLR, a 10ohm from Vdd to Avv, a 1uF cap across the primary vdd/vss line, and I have the cables all hooked up...
clock out contents of visi register
I've been working on a programmer for the dspic33\24-series and I'm on the final stage.
I have all the binary files setup to write to the chip, disassembling the microchip firmware and I'm using python to send these over the serial port. And a BS2 for MCLR...
Okay, so I built the IDC2 clone, and I'm missing one component (lost to my room's sly habit of making things dissapear. The one component is the oscillator :\
What would happen if I put in a 16mhz ceramic oscillator into the circuit rather than the 20mhz? Is there some sort of internal looping...
in system programing on the pic 18f4550
I believe that any arbirtrary system could propriaterily program your PIC, probably even with those particular pins. The trick is in getting the code which will write correct sequences with proper timing to actually have the code get into the...
I built a Schaer+ and programmed my 18f with it, then tried to use it to program my ds30, and it didn't work.
Checked the pinout, realized the difference in pins, and corrected them all save one.
I was wondering if anybody knew the ds30 equivalent of the 18f's RD/AN5/RE0
Thanks

Alright, I decided to try the Schaer, but I had no 7407N's to use, so instead I'm using hex inverters as my buffer, then feeding the inverted signal into a multiplexer, then used a BASIC stamp to both control a transistor network from the op-amped signal, then the...
Multiplexer
If you have a multiplexer which has an output set to ground, will the signal that's getting muxed into the output go to ground, or would the input voltage fluctuate at all?
Trying to imagine a mux backwards connected to a memory grouping :\
ds pic30f programmer
I used the PG1 circuit from Olimex to create the programming circuit. I'm not sure which software is supposed to work with the dsPIC30f, since it seems that a lot of examples that people give to you are pointed towards chip programmers that don't have it in its choices...
