Hi !

So I modified my program inspiring from your code and it seems to work very well !

Thanks

Hi ! Thank you for your answer ! So I noticed your algorithm is something like : - HID_Enable - try HID_Write - If fail : HID_Disable, then return to HID_Enable, try HID_Write... In mine, I just do HID_Enable() once, in the very top of my program, and then try and retry HID_Write to get return value...

Hi there ! I'm currently working on a project with PIC 18F2550 in which I need to check the USB HID status but I can't find how I can do that. The project must be able to run "alone" (without PC), or connected to a PC over USB for configuration and advanced features. My problem is how to have the in...

Hi ! Thanks for your answers ! So, Milos, I tried your code and that is what happens : - If SD card is plugged in, none of the Leds glows. - If SD card isn't plugged, led2 glows... So I think it is stuck in MMC_ fat_init ()... I checked timings of the uC and for a test with LEDS using delay_ms () ro...

Hi ! Yes, my SD card is powered in 3.3 V, using three diodes in series from the 5V, I checked the Vcc pin of the SD and it is 3.23V. Off couse, lines from the PIC connected to the SD are dropped to 3.3V using resistors. I recently added a 10k pull-up resistor on the output pin of the SD and now Mmc_...

Hi !

Thanks for your answer !
So here's the complete project (attached *.zip file).

Hope you'll be able to help me, I think it's an issue from me, because MikroC Compilers is used to work nice ^^


Thanks !!

Thanks for your answer, milos, The card used for my tests is a 2GB SanDisk MicroSD. I checked in the datasheet if it supports SPI : all right. So it is formatted in FAT 16 using Windows 7. But even if it was a formatting problem, won't Mmc_format () routine format it as it wants it to be ? I'll try ...

Hi !

I'm wondering something : maybe SPI needs the use of an external clock source ? I'm using int osc.

Has someone ever tried SPI or MMC/SD Card with PIC 18F4550 ?

Hello ! Thanks for your answers ! I tried what you said, changing RB7_bit into LATB7_bit and then I programmed... Still the same... It seems to stay stuck into Mmc_Fat_Init() routine. I also tried just Mmc_Init() routine but I've got the same issue.. Here I give you a screenshot of my project settin...

Hi ! I'm on a project that needs my 18F4550 to communicate with an SD Card using SPI so I tried MikroC SD/MMC Libraries but I can't get it work. The problem is that my PIC goes to Mmc_Init() routines but seems to get stuck in there. In explaination, I made a simple code to try it : It uses two LEDs....

Thanks for your answers !

Toley, your screenshot is quite interesting )

I've already seen topics explaining that EasyPIC6 is not hardware compatible with K-series, yes..

Ok, so let's wait for Monday to have a MikroE Team answer !

see you,
dadoubou

Thanks for your answer,
I hope you're right

Is there a MikroE team member to confirm that, please ?

Have a good day !

Hi there ! I'm starting a project using a 18F45K50 as µC, I already bought some of these to make some tests, thinking my EasyPIC6 will program it but it CAN'T !! So I thought EasyPIC v7 or MikroProg could program it but it seems not to be truth, so could you tell me if there is a MikroE solution to ...

After some tries, It seems that it also works with the '64's...

Strange behaviors those PICs ^^

Problem seems to be solved ! I just replaced each '64' with an '8' in the example and in the 'USBdc.c', and I set 480h to 488h for the USB RAM adresses. So the example looks like this to work with a 18F2450 : unsigned char readbuff[8] absolute 0x480; // Buffers should be in USB RAM, please consult d...
