Re: SMT Programming

> But wait! you can also buy SOIC test clips that clip onto soldered-in SOICs and will work just fine for ICSP of SOICs. Of course, I discovered this AFTER I went to all that trouble.<p>That sounds like a great solution. The SMT ZIF sockets I've seen are hideously expensive and you don't need to add...

Re: SMT Programming

I built an adapter using .1" breakaway pins and a custom PCB. I tinned only the pads that are required for progamming and hot glued some scrap PCB to help align the part over the pads. I insert the chip into the adapter and apply finger pressure to make sure the pins make contact with the pad. This ...

Re: I2C terminal for pc

I think what your asking is for some simple routines to do RS-232 comm with a PC for debugging purposes. This is easily achieved with minimal hardware. I forego a TTL->RS232 level shifter in favor of a couple of resistors all the time in my designs and, at speeds <= 9600 baud never have any trouble ...

Re: PICing it or How I learned to love Microcontrollers

Chris,<p>I've been reading your posts and trying to figure out your argument. I can't decide if you think PICs (really, uC in general) are overkill or if they are under-achievers. I've seen many, beginner uC projects and books that don't do much more than give one simple programs that could easily b...

Re: OTP Replacement for PIC16f84

> Are they flash as well? Does Picbasic work with them as easily as the 16f84? Can I access there A/D with Picbasic standard or must I have pro?<p>Yes, They are flash based so they can be reprogrammed numerous times. The memory layouts and ports are very similar so most code should work no problem. ...

Re: OTP Replacement for PIC16f84

If you can modify the code slightly then consider porting to a PIC 16F627A or 16F819. For the most part you need only add a few instructions to set the comparators and A/D off. These chips are about 1/3 the cost of the 16F84 (why? I have no idea) and have more features. You can even utilize their in...
