thankyou for the hex file for my fluffy 2. now i need to know one last thing. i bought everything on the parts list. and i have 3 ic sockets 18 pin. the 16f84 fitted perfectly but the max232cpe has 16 pins. so obviously there will be 2 pins from the socket not used. another thing is that all the pins for the max232 are used. can someone tell me what wrong? thanks guys
well the max232CPE is a 16 pin chip
on the parts list which i just copy pasted from the one on the site it seems he might have made a small mistake on the sockets needed cause all u need is 2 18 pin 1 16pin and 1 28 pin
however if u have 2 8pin sockets which u may have used for pic12C508/9 chips just put 2 8pin dips lined up and u'll have your 16 pin socket
or u can just go grab one at your local eletronics dealer
oh ya and i forgot to say that on the design thats found on the fluffy2 site if u look at the completed picture found on the site you'll notice he didnt use a dip for the max232CPE its soldered directly onto the pcb
guys i finished the my fluffy 2 but i got a small problem i got 3 holes which are near the pic16f84 and 4 pins on the empty 18 pin socket. i dunno how to connect them to the pc
i also got another 2 holes in the upper part but those are for the 18v .... please hel me thanks a lot
What equivalent did you use for ztx ?
the 4 holes near the sx socket are for in circuit programming (ICP) and are not necessary
the 3 holes on the board edge near the pic are for connection to the serial port on your pc, for a 9 pin connector you connect ground or common on the fluffy to pin 5 on the serial, the pin closest to the capacitors around the max232 goes to pin 2 on the serial and pin 3 on the serial goes to the middle pin.
hope this helps, the schematic of the circuit shows this clearly
Since so many people are building the fluffy2, I was wondering if the pcb is available somewhere for purchase?
