Sorry... I work with ponyprog only with AVR family... I don´t like Microchip. -----Mensagem original----- De: abbas raftari [mailto:araftary1@yahoo.com] Enviada em: quarta-feira, 20 de outubro de 2004 09:39 Para: avr-chat@yahoogroups.com Cc: araftary1@yahoo.com Assunto: [AVR-Chat

Good question. I've heard of the Ponyprog but I'm not familiar with it. I thought it just programmed PIC's. I use a MicroEngineering EPIC Plus programmer for PIC's and have had no trouble with it at all. They update their software every time a new device comes out. I have had no

Hi; I work with Ponyprog program for AVR & PIC programing . I made a SI-prog programer and PIC programer adapter for PIC programing. I can program (read & write) many PIC series for exampel 16F84A but I can't program PIC 12C5xx series. I can just only read it but i can't write it

We have a chain of stores locally that sells loads of things, all at 1UK pound. Most interesting lately were some mobile telephone chargers intended for use in a car.They contained a complete switching regulator - already set to 5V and capable of delivering a few hundred milliAmp

I used SPASM, an 8051-like assembler for PIC's, but when I looked at the code generated and the redundancy in some cases, I stuck with Microchip MPASM assembler to write programs. Mine always came out quite a bit shorter. I haven't tried any program that uses 8051-like assembler

Actually with the butterfly, programming is real simple, it has a serial port on it, you just need to wire it up, you can get the info from the datasheet. - Mike On Tue, 19 Oct 2004 09:07:12 +1000, Dingo wrote: > > I remember a person posting photos of his AVR based lock over on

Hi Gang...!! I was searching for a new MCU and started looking at the AVR line of MCU chips. I had seen the butterfly card for $20 and having read the chat from here decided to get the "carrier" board kit from echos for $20 to go with that. I also got the Bascom program for $85 f

I've seen this before - the 2 pin approach is to use the transmitter in a "push-pull" manner. set pin A to high and pin B to low, after 12.5 uS, pin A to low and pin B to high. wait 12.5 uS, repeat for the number of cycles you want in your pulse. You could also just connect one p
