Hi Benj,
Finally found the problem - I was using an old ECIO programmer. On using mLoader it run first time and code is performing as expected with compiler switches as suggested. Thanks for your help.

Further investigation revealed that the hex file generated by the hitech compiler does not load properly even though the hex output format is inhx032. When read back via the programmer the device is empty ! Eyeballing the hex file and comparing it with a working FCV4 hex file they look similar in fo...

Hi Benj, When I load a FCV4 test programme via the ECIO programmer it loads and only runs when I issue a reset command ( ^T). When the HITECH compiled code is loaded it fails to run after a reset. Looking at the hex file : in the flowcode example the code starts thus 1025 0800 EF26 GOTO 0x84c 1026 0...

Hi Benj,
Soruce and .hex attached.

Hi Benj, Thanks for your detailed reply, however I still cannot get it to load correctly after setting switches as suggested. I am using picc-18 ver 9.63 in lite mode. On peeking the .hex file code in my application is offset at 0x800 but a bulk of the code is loaded at the top ( high address) end o...

I am using the ECIO programmer in standalone mode and tried to load the hex file compiled under MPLAB V 8.76. The file loads and attempts program the device but fails to complete. The last block fails to load and led remains in a flashing state. It does this also with a pre-compiled code from fCV4. ...

Further to my last post. This test code works fine on on a PIC18F452.

Hi Benj,

Code attached. When blown into ECIO 28 I2C pins on port B just generate a single square pulse. BTW the port D problem goes away if you select software settings on I2C component properties and select bits 1 and 0. This should be the default setting for the 28 pin Pic18F2455.

Hi, I have a compiled a simple programme to access the I2C bus, but the compiler throws an exception C:\teaching\b38DB\display3.c(250:4): error: unknown identifier 'trisd' C:\teaching\b38DB\display3.c(250:4): error: invalid operand 'trisd' C:\teaching\b38DB\display3.c(250:11): error: failed to gener...

Hi Medelec35, Thanks for the information. My compile target is PIC18F452 That's interesting because sprintf is listed in the boostC compiler manual; that's why I used it. Also when I requested a return value of string pointer the macro ( function ) it constructed in the C listed it as returning void...

I have a C-code macro thus in FCV4.1 C-code macro #include <stdio.h> FCL_TEMP=sprintf(FCL_TEMP,"%d-150",FCL_NUMB); return(FCL_TEMP); and compiler, when compile to chip is select returns an C:\PROGRA~1\MATRIX~1\FLOWCO~2\BoostC\include\stdio.h(17): error: missing right paren C:\PROGRA~1\MATRIX~1\FLOWC...

I have the same problem - it won't recognise the chip. I'm using an EB006 development board
