I'm wondering why I'm getting lots of these warnings - (A12004) Value is truncated to two bytes. ?? They are all indicated with a JSR instruction. The code compiles and runs - but since I moved some of the routines into paged memory, rather then the non paged area - I get these warnings. Do I need to change a setting in CodeWarrior ? I know you have to be careful with JSR and paged memory...

Hello, I am using a Wytec microdragon with serial monitor & trying to get a 25ms interrupt. I had it working in a previous similar project, so I believe the code should work. The keypad & lcd work fine. My question is: is there some input pin that could be affecting the modulus counter? As soon as the interrupts turn on all control is lost. Any code after (interrupts_on) is not executed - Je...

Hello, I am using 5 mhz CLK in source and i need 1.25 mhz Bus clk so i used internal PLL for that ,i have done following thing for that is 1)SYNR=00; 2)REFDIV=03; EX CODE IS: /*PLLCTL=0xB1; /*PLL off */ /*goto PLL_BYPASS; */ CLKSEL=0x00; REFDV=03; /* BUSCLK=5MHZ*(0+1)/(3+1) */ SYNR=00; Lock_loop: for (i=0; i < 30000;i++){} /* Delay some time ... */ bit=CRGFLG & LOCK; if(bit ==0x00)

Hi everyone I am using the the Dragon 12 Plus and the GNU compiler. I am having a major problem using interrupts to completing my project. For my project I am using a sensor to measure a distance and when the distance is under 30 ins it should activate a timer that would count to 10 (displayed on the seven segment) and stop but if the sensor measures under 30 ins again it should restart the count...

I'm very new to embedded systems programming and learning about scheduling. I am getting a Trigger A occurred in the command window of the debugger when I hit RUN. When I step through the code it seems to reset? at asm cli at the end of the code. Please let me know if you all have any ideas. /* Started with Valvano Fixed Priority Scheduler.

Hello, I am going t use 9s12d64 for my older design with replacing this.In older design MC68HC11 was used.on that design an FPGA used on 0x8000 to 0x803f adress.So now i wanted to use same adress for an FPGA so is it possible in 9s12d64 controller? Since i have read that 0x8000 to 0xBFFF is used for program memory using page window.And insight of micro internal flash is available in this locatio...

Hello; I am using an ICC12 compiler and NOICE debugger with a USB pod with an HC12 128kB chip running with a 16MHz crystal. My problem is that when I try to set the PLL up for about 40MHz, the code does not seem to work in the way it should and I can't get a LOCK - or even a TRACK signal. I have to turn off the PLLSEL bit before trying to set up the mult and divide registers and turning the...
