Is there a lib for SSD1306 I2c OLED displays ?


Thankyou

What would cause this command to hang ?

Using Mmc_Fat_Assign(filename, 0) to get known files from the card

Working OK most of the time, then suddenly won't get past the command.


Any ideas ?



Thanks

What's the maximum filename length that can be used with this library ?


Thanks

filename = "TESTFILE.txt"
FAT32_Open(@filename, FILE_WRITE_F32)
FAT32_Dir()
FAT32_Put_Char(SD_data)
FAT32_Write(0, @SD_data, 1)
FAT32_Close(0)

The above does not work.

How do you test that the Dir command has finished ?

How do I read the directory and store it (as a text file) on the card ?

Thanks

The FAT32_Read command in this code example is locking up. Any ideas why ? filename = "TestFile.txt" FAT32_Open(@filename, FILE_READ_F32) FAT32_Size(@filename, @filesize) while filesize > 0 SRAM_addr_lo = lo(SD_addr) SRAM_addr_hi = hi(SD_addr) FAT32_Read(0, @SD_data, 1) 'PROBLEM HERE !!! SRAM_data =...

Which MCU and development board are you using?

PIC18F4525 on my own board.

The circuit works, and when it initialises, the software works too.

What can influence the SPI module and cause problems ?

I'm having trouble with initialising - SPI1_Init_Advanced(_SPI_MASTER_OSC_DIV64, _SPI_DATA_SAMPLE_MIDDLE, _SPI_CLK_IDLE_LOW, _SPI_LOW_2_HIGH) while FAT32_Init() <> 0 wend SPI1_Init_Advanced(_SPI_MASTER_OSC_DIV4, _SPI_DATA_SAMPLE_MIDDLE, _SPI_CLK_IDLE_LOW, _SPI_LOW_2_HIGH) It either never initialises...

Thankyou. (it didn't say _F32 in the help file)


BTW is it possible to get the number of files in a directory ?

Also, is it possible to read all the filenames in a directory (and place into an array) ?

I'm using the FAT32 lib with mikroe Basic pro for PIC. The following throws up the error - filename = 'TestFile.txt' FAT32_Open(@filename, FILE_READ) 248 303 Identifier "FILE_READ" was not declared Test.mbas 248 301 ")"is not valid identifier Test.mbas 249 304 Syntax error: Expected "end" but "FAT32...

I've downloaded the FAT32 .mpkg file, but in ver 7.1.0 (because I'm using WinXP) I can't find a way to install it. I must be missing something.

Are you sure that you have set OSCCON and OSCTUNE registers properly while going through internal oscillator block?

I will check that.

BTW how do you install new libraries (such as FAT32) into mikroBasic Pro ver 7.1.0 ?

Does it have to be manually placed into a folder somewhere ?


Thanks

Swapped over to an external oscillator, and it's now appears to work OK.

AAMOI does the FAT32 library work with a PIC18F4520 ?

Also, I cannot find the help for the library.

Just came back to this (code based on the MMC example) I'm getting no read from the card, or partial reads before it corrupts. I've also had the file not being assigned and the file I'm trying to read get corrupted on the SD card. I'm using a ready-built SD card module (with built-in level shifters)...

Is it OK to use the internal oscillator (32MHz) when using the MMC card functions ?

I'm having some read problems, and was wondering if that could be the cause.


Thankyou
