The MMC e-block has two constraits with flowcode and the multiprogrammer:
1) All 16 Series chips are out and many 18 also, such as 18F2455 on memory grounds.
2) Many 18 series chips split SDI/SDO accross two ports so are unsuitable for harware SPI.
Any suggestion of a chip than has been used successfully used on either the Multiprogrammer or HP-488 boards directly with flowcode?
Thanks.

Re: EB037 MMC Card Reader e-block, Suitable Chips
Hi Mark
Have a look at my Temp Logger Project, I use the MMC card reader on that
http://www.matrixmultimedia.com/mmforum ... emperature
I tried both the 18F4550 and the 18F4455
Did initally find the E-block would only work with a class 2 SD card, after chatting with Benj I added a delay to the custom component and that got it to work with the class 4 sd card.
Not tried using it on the FC4.5 so dont know if the mod is still needed.
