hi everyone
was woundering if it could be done and if so how
i'll try to show in my example below
and trying to get more of an understanding of how to make an adapter for this to be able
to plug a sim card into the adapter and use the sd slot to read & write from
[sim card]
1 vcc 4 ground
2 reset 5 vpp
3 clock 6 in/out
----------------------------
[sd mem card]
1 CD/DAT3 I/O/PP Card detection / Connector data line 3 CS I Chip selection in low status
2 CMD PP Command/Response line DI I Data input
3 Vss1 S Supply voltage (earth) VSS S Supply voltage
4 Vdd S Power supply VDD S Power supply
5 CLK I Clock SCLK I Clock
6 Vss2 S Supply voltage VSS2 S Supply voltage
7 DAT0 I/O/PP Connector data line 0 DO O/PP Data output
8 DAT1 I/O/PP Connector data line 1 RSV
9 DAT2 I/O/PP Connector data line 2 RSV
sim to sd
1 6
4 3
6 7or 1
3 5
if someone could help me figure this out i would really appreciate it so much
this would just give me more of an idea on how these things click
thank you for reading my post
have a great day
