FAT16_32 via SoftSPI

· Posted: 27.06.2020 - 15:08 · #1

Ich verwende gerade eine SD-Karte via Soft-SPI und habe folgendes festgestellt .....

funktioniert:

Code

  FAT16           = MMC_Soft, iData;
  F16_MMCPort     = PortA.3,PortA.1,PortA.2,PortA.0;
  F16_MMCspeed    = standard;               { standard, slow, fast             }
  F16_FileHandles = 1;
  F16_DirLevels   = 1;
  F16_StrLen      = 90;

Im Handbuch staht, daß das erlaubt ist:

Quote

Define
FAT16 = MMC_SOFT, iData;
F16_MMCport = PortX, SS, SCK, MOSI, MISO;

Das funktioniert aber nicht:

Code

F16_MMCPort = PortA,3,1,2,0;

Will jemand danach schauen?

Gruss

When you say it doesn't work, what do you mean? Doesn't compile or doesn't function?

Bizzarely, I get the opposite;

Code

F16_MMCPort = PortA,3,1,2,0;

works, but

Code

F16_MMCPort = PortA.3,PortA.1,PortA.2,PortA.0;

does not

Perhaps you should publish your full unit so we can see what the differences are.

Here is mine

Code

program Test;

Device = mega2560, VCC=5;

import SerPort1, FAT16;

define
  ProcClock      = 16000000;
  StackSize      = 512, iData;
  FrameSize      = 512, iData;
  SerPort1       = 19200, Stop1;
  RxBuffer1      = 128, iData;
  TxBuffer1      = 128, iData;
  FAT16           = MMC_Soft, iData;
  //F16_MMCPort     = PortA.3,PortA.1,PortA.2,PortA.0;
  F16_MMCPort     = PortA,3,1,2,0;
  F16_MMCspeed    = standard;               { standard, slow, fast             }
  F16_FileHandles = 1;
  F16_DirLevels   = 1;
  F16_StrLen      = 90;

Uses UFAT16;

Implementation

const

type

var
{$IDATA}

begin
  EnableInts;
  loop
  endloop;
end.
