Counting led blinks..

**tacbanon** · - 3rd November 2011, 10:10

Hi, I'm sorry about that(I'm misleading the thread), anyway I borrowed an sdcard from a friend...but he never tested it yet and doesn't have datasheet..hopefully I don't blow it up

Here are the List I done & planning to do on my project in this thread.
1. Use Timer/Counter from TIMER0 for multi coin-acceptor(pic16F877 and 18F4550) -Done
2. Test RTC and Sdcard separate program- Done
3. Incorporating Multi coin acceptor-RTC and Keypad on 4550 - Done (I need the keypad for access and view settings.)
4. Incorporate SDcard for saving RTC data and number of coins dropped - not yet
5. Use USB CDC to dump data(rtc and number of coins) from SDcard to terminal communicator - not yet

I appreciated the help and the knowledge I got on this forum...not easy task(for me) but you encourage me to try it out...

thanks again,
tacbanon

Hi, I have only one 4550 and I want to try it to another chip, I only have pic18f2550..I followed some instructions to comment the default config fuse in PBP INC files. I tried to compile this part of the code..

Code:

    '<FL_PIC18F2550>'    '<FL_PBPL>'
    DEFINE OSC 48

    @ __CONFIG   _CONFIG3H, _PBADEN_OFF_3H & _MCLRE_OFF_3H
    @ __CONFIG   _CONFIG4L, _LVP_OFF_4L & _XINST_OFF_4L
    Include "modedefs.bas"
        ' Alias PIC pins and registers for SD/MMC card

    SDO_TRIS     VAR    TRISC.1    ' SPI data out direction

But gives me the following compilation error...

Use the same configs for the 2550 as you did for the 4550.

The only thing you need to do to move to the 2550 is change some pin assignments if you were using some on the 4550 that the 2550 does not have.

Make sure you have all of the needed files in the new project directory.

Thanks mackrackit, I just found out that the sdcard module I ordered will take a while(2weeks from china). The sdcard I borrowed did not work either.In the meantime...I will be working on the keypad codes for accessibility feature of this project...be back soon.

Hi, I got my new sdcard just the other day...now I've been trying to make following code work... I did tried to connect to another ports/pins but was not able to make it run.

The alias PIC pins and registers for SDcard is a copy from Macrackit, Can you tell me what I'm doing wrong?
The alias pins below works with no problem..

Code:

' Alias PIC pins and registers for SD/MMC card
SD_WE        Var    PORTA.4    ' SD card write protect
SD_WE_TRIS    Var    TRISA.4    ' SD card write protect direction
SDI        Var    PORTB.0    ' SPI data in
SDI_TRIS    Var    TRISB.0    ' SPI data in direction
SCL        Var    PORTB.1    ' SPI clock
SCL_TRIS    Var    TRISB.1    ' SPI clock direction
SD_CS        Var    PORTB.3    ' SD card chip select
SD_CS_TRIS    Var    TRISB.3    ' SD card chip select direction
SD_CD        Var    PORTB.4    ' SD card detect
SD_CD_TRIS    Var    TRISB.4    ' SD card detect direction
SDO        Var    PORTC.7    ' SPI data out
SDO_TRIS    Var    TRISC.7    ' SPI data out direction

But I want to move the pins off from PortB.

Thanks and regards,
tacbanon

What errors are you getting?

**tacbanon** · - 26th November 2011, 23:59

Hi macrackit, I do not have any errors, I've been playing with it the whole night last night but no progress...
I also tried the following alias pins configurations from a book..(uising pic18F452) but no luck.

Code:

 ' Alias PIC pins and registers for SD/MMC card
    SD_WE        VAR    PORTA.4    ' SD card write protect
    SD_WE_TRIS   VAR    TRISA.4    ' SD card write protect direction
    SDI          VAR    PORTC.5    ' SPI data in SD #7
    SDI_TRIS     VAR    TRISC.5    ' SPI data in direction
    SCL          VAR    PORTC.3    ' SPI clock  SD #5
    SCL_TRIS     VAR    TRISC.3    ' SPI clock direction
    SD_CS        VAR    PORTC.2    ' SD card chip select SD #1
    SD_CS_TRIS   VAR    TRISC.2    ' SD card chip select direction
    SD_CD        VAR    PORTC.0    ' SD card detect
    SD_CD_TRIS   VAR    TRISC.0    ' SD card detect direction
    SDO          VAR    PORTC.4    ' SPI data out   SD #2
    SDO_TRIS     VAR    TRISC.4    ' SPI data out direction

Hmm..I don't understand, CS -> RB3, MOSI -> RC7, SCLK -> RB1 and MISO -> RB0 works fine without a problem, but assigning them to another port/pins giving me trouble.

(BTW I'm using Pic18F4550, crystal 20Mhz)

Hi, Sorry I spoke too soon, this is what I get when I'm trying to transfer to another port/pins "’nit: 6 2 0"

**mackrackit** · - 27th November 2011, 01:43

From the SDFS file, the 6 and 2 from the generated errors.

CE_INIT_ERROR Con 6 ' An initialization error has occured
sdcCardNotInitFailure Con 2

From section 10.3 18F4550 data sheet.

On a Power-on Reset, these pins, except
RC4 and RC5, are configured as digital
inputs. To use pins RC4 and RC5 as digi-
tal inputs, the USB module must be dis-
abled (UCON<3> = 0) and the on-chip
USB transceiver must be disabled
(UCFG<3> = 1).

And do you have the Capture / Compare turned off for PORTC?

**tacbanon** · - 27th November 2011, 04:10

SDC_UseHardSPI = TRUE ' Use hardware SSP port for SPI.

Should be FALSE

**tacbanon** · - 27th November 2011, 14:29

That was it Dave, thank you for sharing your time...

But I have another question, can I still make USB CDC with the setup we modified?regards,tacbanon

**mackrackit** · - 27th November 2011, 15:33

RC4 and RC5 are the USB pins.
