Re: Where are all the Minimigs?

RE PIC programming questions, it is possible to assemble a cheap programmer out of readily available parts.

The Minimig currently uses a PIC18LF252. I think 'F' refers to Flash memory. Can anyone tell me what the 'L' stands for?

I am currently assuming the PIC18LF252 is pin compatible with the PIC18F252. If this is the case, this is a suitable PIC programming solution:

Website: http://www.ic-prog.com/index1.htm
Hardware: http://www.ic-prog.com/ER1400.jpg
Software: http://www.ic-prog.com/download.html
More Software: http://www.electronics-lab.com/downloads/mcu/001/index.html

Can someone with more electronics experience please tell me if the ER1400 programmer will support the PIC18LF252. Thanks.

@henry case

why u want to build it your own if u can buy them for cheap on ripoffbay?


I didn't realise you could buy PIC programmers so cheaply off eBay, thanks for the tip Amazing. If anyone living in the UK is looking for a cheap PIC programmer (that will work with the Minimig PIC chip I believe), check this out: http://tinyurl.com/yru47g

According to the Digi-Key catalog the LF version operates with a VCC range of 2.0 ~ 5.5V and the F version with a range of 4.2 ~ 5.5V :-)


CD32Freak, thanks for the info. So I'm guessing L = Low Voltage.

By the way, the RoHS Replacement of PIC18LF252-I/SP is the PIC18LF2520-I/SP and the RoHS Replacement of PIC18F252-I/SP is the PIC18F2520-I/SP ;-)


I got the part name off the American Digikey price list I found on this forum. Am I right in thinking the US doesn't have to follow RoHS guidelines (I thought it was a EU directive)?

Another question, where is the best place to get MMC cards that work the best with Minimeg?


Pyromania, I wanted to reply to this because I've seen you ask this question a couple of times without much of a response.

I guess as one of the early owners of a Minimig, the responsibility for finding the best supplier of MMCs might be down to you (trial and error and all that). However, that isn't being helpful. Take a look at this picture:

Looks like Dennis used an Apacer MMC.
Google US product search:
http://www.google.com/products?hl=en&q=Apacer+MMC&um=1&ie=UTF-8
So prices are around $17.98 USD for a 1GB card.

Hope that helps.

Thanks very much for the info HenryCase, now if I can only track down that elusive power supply for the USA.


Would any of these be suitable as a Minimig power supply?

I'm going on info from wizard66's post, but I really don't have much of a clue!
