OK, cutting and pasting just the config lines into a blank page in Microcode studio, remming out the config lines in the 18F2550.INC file in the PBP folder so as not to get the warnings about overwritting values I can confirm that the LST file produces the same results as yoursOriginally Posted by mister_e

Like I said, I'm a little out of my depth, so can't shed any light why or what the settings / numbers mean, I can only report them back to you. The only other programmer I have is a PicKit1, which doesn't support these devices
Where those numer comes from. Open the p18F2550.INC in the MPASM foler, scroll to the bottom and you'll discover
let's see CONFIG1L and CONFIG1H optionsCode:_CONFIG1L EQU H'300000' _CONFIG1H EQU H'300001' _CONFIG2L EQU H'300002' _CONFIG2H EQU H'300003' _CONFIG3H EQU H'300005' _CONFIG4L EQU H'300006'
using our settings, we keepCode:;----- CONFIG1L Options -------------------------------------------------- _PLLDIV_1_1L EQU H'F8' ; No prescale (4 MHz oscillator input drives PLL directly) _PLLDIV_2_1L EQU H'F9' ; Divide by 2 (8 MHz oscillator input) _PLLDIV_3_1L EQU H'FA' ; Divide by 3 (12 MHz oscillator input) _PLLDIV_4_1L EQU H'FB' ; Divide by 4 (16 MHz oscillator input) _PLLDIV_5_1L EQU H'FC' ; Divide by 5 (20 MHz oscillator input) _PLLDIV_6_1L EQU H'FD' ; Divide by 6 (24 MHz oscillator input) _PLLDIV_10_1L EQU H'FE' ; Divide by 10 (40 MHz oscillator input) _PLLDIV_12_1L EQU H'FF' ; Divide by 12 (48 MHz oscillator input) _CPUDIV_OSC1_PLL2_1L EQU H'E7' ; [OSC1/OSC2 Src: /1][96 MHz PLL Src: /2] _CPUDIV_OSC2_PLL3_1L EQU H'EF' ; [OSC1/OSC2 Src: /2][96 MHz PLL Src: /3] _CPUDIV_OSC3_PLL4_1L EQU H'F7' ; [OSC1/OSC2 Src: /3][96 MHz PLL Src: /4] _CPUDIV_OSC4_PLL6_1L EQU H'FF' ; [OSC1/OSC2 Src: /4][96 MHz PLL Src: /6] _USBDIV_1_1L EQU H'DF' ; USB clock source comes directly from the primary oscillator block with no postscale _USBDIV_2_1L EQU H'FF' ; USB clock source comes from the 96 MHz PLL divided by 2 ;----- CONFIG1H Options -------------------------------------------------- _FOSC_XT_XT_1H EQU H'F0' ; XT oscillator, XT used by USB _FOSC_XTPLL_XT_1H EQU H'F2' ; XT oscillator, PLL enabled, XT used by USB _FOSC_ECIO_EC_1H EQU H'F4' ; External clock, port function on RA6, EC used by USB _FOSC_EC_EC_1H EQU H'F5' ; External clock, CLKOUT on RA6, EC used by USB _FOSC_ECPLLIO_EC_1H EQU H'F6' ; External clock, PLL enabled, port function on RA6, EC used by USB _FOSC_ECPLL_EC_1H EQU H'F7' ; External clock, PLL enabled, CLKOUT on RA6, EC used by USB _FOSC_INTOSCIO_EC_1H EQU H'F8' ; Internal oscillator, port function on RA6, EC used by USB _FOSC_INTOSC_EC_1H EQU H'F9' ; Internal oscillator, CLKOUT on RA6, EC used by USB _FOSC_INTOSC_XT_1H EQU H'FA' ; Internal oscillator, XT used by USB _FOSC_INTOSC_HS_1H EQU H'FB' ; Internal oscillator, HS used by USB _FOSC_HS_1H EQU H'FC' ; HS oscillator, HS used by USB _FOSC_HSPLL_HS_1H EQU H'FE' ; HS oscillator, PLL enabled, HS used by USB _FCMEN_OFF_1H EQU H'BF' ; Fail-Safe Clock Monitor disabled _FCMEN_ON_1H EQU H'FF' ; Fail-Safe Clock Monitor enabled _IESO_OFF_1H EQU H'7F' ; Oscillator Switchover mode disabled _IESO_ON_1H EQU H'FF' ; Oscillator Switchover mode enabled
combining both L and H we have F0E7... same for all other Config stuff.Code:_CONFIG1L EQU H'300000' _CONFIG1H EQU H'300001' _CPUDIV_OSC1_PLL2_1L EQU H'E7' _FOSC_XT_XT_1H EQU H'F0'
It doesn't explain your config2 stuff... If it's a config fuse, it's not valid, well i don't see how we can have 1F... it could be a device programmer behaviour... i think
OK copying and pasting that example into a blank page on Microcode studio and hitting F9 to compile produces an error. 113 (path and file name).asm59: symbol not previously defined (_FCMEN_OFF_1H)let's try to set ALL available config fuses BUT NOT the code protect stuff. And while we're at it, let's try a simple program too.
Code:ASM __CONFIG _CONFIG1L, _PLLDIV_1_1L & _CPUDIV_OSC1_PLL2_1L & _USBDIV_1_1L __CONFIG _CONFIG1H, _FOSC_XT_XT_1H & _FCMEN_OFF_1H & _IESO_OFF_1H __CONFIG _CONFIG2L, _PWRT_ON_2L & _BOR_ON_2L & _BORV_1_2L & _VREGEN_OFF_2L __CONFIG _CONFIG2H, _WDT_OFF_2H __CONFIG _CONFIG3H, _MCLRE_ON_3H & _LPT1OSC_OFF_3H & _PBADEN_OFF_3H & _CCP2MX_OFF_3H __CONFIG _CONFIG4L, _STVREN_ON_4L & _LVP_OFF_4L & _XINST_OFF_4L & _DEBUG_OFF_4L ENDASM ADCON1=$0F TRISB=%00000000 'set PORTB as all output PORTB=0 ByteA var byte main: for bytea=0 to 7 PORTB=DCD BYTEA PAUSE 250 NEXT PORTB=255 PAUSE 250 goto main
Regret that I can't see where the error is coming from as there is nothing in the INC file (BPB folder) or am I looking in the wrong place?now it give us those config values
and it's still working here. here's the .HEX dumpCode:00102 __CONFIG _CONFIG1L, _PLLDIV_1_1L & _CPUDIV_OSC1_PLL2_1L & _USBDIV_1_1L 300000 30C0 00103 __CONFIG _CONFIG1H, _FOSC_XT_XT_1H & _FCMEN_OFF_1H & _IESO_OFF_1H 00104 __CONFIG _CONFIG2L, _PWRT_ON_2L & _BOR_ON_2L & _BORV_1_2L & _VREGEN_OFF_2L 300002 FECE 00105 __CONFIG _CONFIG2H, _WDT_OFF_2H 300004 F8FF 00106 __CONFIG _CONFIG3H, _MCLRE_ON_3H & _LPT1OSC_OFF_3H & _PBADEN_OFF_3H & _CCP2MX_OFF_3H 300006 FFBB 00107 __CONFIG _CONFIG4L, _STVREN_ON_4L & _LVP_OFF_4L & _XINST_OFF_4L & _DEBUG_OFF_4L 00108

Yes - JDM as detailed above, with the chip pluged in to the programmer rathet than using ISCPWich adapter you're using JDM?
ICSP or not?
I've tried grounding PGM with a wire whilst programming and leaving the jumper off, whilst programming the code in post# above the config settings in Winpic are displayed as FFFF and FFFF (config word 1 and 2), and with PGM grounded the programming failed. I erased and read back the PIC to make sure there was no code in the PIC. Disconnected the serial cable and re-connected, re-launched WinPIC and loaded the same code. Again it errored when programming. I then used PICpgm to program the code - it reported it programmed without errors (I did erase the PIC first). I then closed PICpgm and re-opened winpic and read the code back in to the application. Under Winpic the config words are reported as CF3F (word 1) and 1F3F (word 2)When you program your PIC, pull the PGM pin to GND, erase the chip firstm then retry and post your results.
I think I might invest in a decent programmer - I have a PICkit1 as mentioned above, and it works really well - maybe I'll treat myself to an early christmas pressy
I can't comment on JDM or else programmer like that, if you want a nice one and cheap, i buyed few months ago a Microchip PICKit 2 for some on-the road service job. For a <40$ and USB PIC programmer it's really nice.
I don't mind trying stuff and it helps learing what and how things work, I just don't want to take up too much of your time in trying to resolve my problem.
Yeah it's kind of hard to know where the problem come from... The most strange thing... only one a single pin... and you tried on another board...
Don't give up!
Many thanks as always
