    [PIC] Using Hardware and Software SPIs wtih 18F8722

    Firstly thank you so much for your kindly replies. My two encoders are linear type magnetic and incremental encoders. Resolution = 5μm 6 outputs but i use A, B channels and Z reference Traverse speed (max) = 2m/s Travel Length = 25 cm Other one is Incremental Rotary encoder. Maximum rpm =...

    [PIC] Using Hardware and Software SPIs wtih 18F8722

    Hello bigdogguru, I should read two encoders at same time and they should move to forward or backward synchronously. On the other hand i want to read one more encoder, not same time with others. So i need three separeted spi lines. As i said 18f8722 has only two HW SPIs. I have already designed...

    [PIC] 18F4550 to read Analog value

    Hi, I use 18 F 4550 to read 12 chanels analog values. I couldn't read values from portB. As you see i use PortE and PortB. I can read form PortE (except one pin) but i couldn't read any value from PortB. I tried many ways but i couldn't find the reason. is there anybody to help me. #include...

    [PIC] Boatloader problem in CCS

    I loaded bootloader to PIC18F2550. And I send my codes several prog. languages. I used theese codes. Only CCS C didn't work. After sebding C codes to PIC, bootloader program gives message like "reset failed". Other programs working nicely. DEFINE RESET_ORG 1000h //it worked PICBASIC Declare...

    [PIC] Boatloader problem in CCS

    I am using usb communication and bootloader provided by microchip. I have already tried codes written with PICBASIC, PROTON and C18. They are work. As you said i tried #include <usb_bootlader.h> but program doesn't work.

    [PIC] Boatloader problem in CCS

    I send my ccs program to PIC18F2550 with bootloader. But it is not work. I have tried with PICBASIC and PROTON. They are worked but my program which written in ccs is not work. What is my mistake? This is my program. #include <18F2550.h> #fuses HSPLL, NOWDT, NOPROTECT, NOLVP, NODEBUG, USBDIV...
