Flowcode V5 AVR with MMC and test with ISIS 7

[ylanchec]

Hi,

I have made a simple software with a FAT16 component and an LCD 16x2, i'm just trying the function Fat16_INIT, it works in simulation but not with a simulation with Proteus 7.

What is the problem ?

Hello,

First of all I recommend that you either output a value to pin B2 or you pull B2 up to VDD using say a 10K resistor. If B2 is left as an input and has a logic low signal then the SPI will go into slave mode and lock up any master SPI communications. This is one to look out for on the AVR devices, caught me out a few times.

What's the Proteus simulation doing? Are you getting any error codes on the LCD?
