  1. Hi Reynard, Thank you very much.... It works fine. Best regards and greetings from germany Coder
  2. Hello, i have a problem with following code: asm { LABEL1: goto LABEL1; } =>internal error: can't add label 'LABEL1' I looked at the forum and found different solutions for that, but nothing works: 1.) asm => _asm the same Error 2.) LABEL1: => LABEL1: => error: error in built-in assembly 3.) :Label1 or :Label1 => error: error in built-in assembly 4.) LABEL1: => _LABEL1: Compiler hangs My equipment: - Windows 7 prof - MPLab X IDE v1.95 - BoostC Optimizing C Compiler Version 7.20 (for PIC16 architecture) - PIC16F1825 Any other suggestions of how to solve this? Please help.... kind regards Coder
  3. Hello, sorry, i found a problem, that i can't understood. Hope someone can help me... I used following code: ########## unsigned char cFilter = 0x80; for (char c=0; c<8; c++) { ToggleOutput(); // toggle a output on the pic cFilter >>= 1; // or /=2; Same result } ########## I connected a Oszi on the output and look at the screen. I saw that the output toggle not on a staibe frequency. It startet slow and with every toggle faster (half time). After some tests i found out, that some changes set the code in correct function: ########## char cFilter = 0x80; for (char c=0; c<8; c++) { ToggleOutput(); // toggle a output on the pic cFilter >>= 1; // or /=2; Same result } ########## Could someone explain me, why this is like that. In the manual we could read: "Use unsigned data types wherever you can, and signed only when necessary" Thank you for your help. Coder
  4. Hi Pavel, ok, nice description. But i'm missing a description of what is done after we report a bug. Would be nice to get a little statement like: - Bug could be reproduced - Solved at version... .... Something like that. Will that be done? Greetings Coder
  5. Hi, there is a problem with all optimation off and the eeprom_write(). The disassembled code looks like this (optimation off): --- E:\Prg\compiler.6\picantc\libc\eeprom\eeprom.c --------------------------------------------- ... 020D 3055 MOVLW 0x55 020E 1683 BSF 0x3, 0x5 020F 1703 BSF 0x3, 0x6 0210 008D MOVWF 0xd 0211 30AA MOVLW 0xaa 0212 1683 BSF 0x3, 0x5 0213 1703 BSF 0x3, 0x6 0214 008D MOVWF 0xd ... The disassembled code for optimation on looks like this: --- E:\Prg\compiler.6\picantc\libc\eeprom\eeprom.c --------------------------------------------- ... 0111 3055 MOVLW 0x55 0112 1683 BSF 0x3, 0x5 0113 1703 BSF 0x3, 0x6 0114 008D MOVWF 0xd 0115 30AA MOVLW 0xaa 0116 008D MOVWF 0xd ... The first version don't work (EEProm not changed). Bankswitching is not needed here, but done if the optimation is off. 0212 1683 BSF 0x3, 0x5 0213 1703 BSF 0x3, 0x6 But this distroed the needed sequence (Writing to Data EEPROM Memory in the datasheet): >>Execute the special five instruction sequence: >>• Write 55h to EECON2 in two steps (first >>to W, then to EECON2) >>• Write AAh to EECON2 in two steps (first >>to W, then to EECON2) Basics: Device: PIC16F876A BoostC Optimizing C Compiler Version 6.96 (for PIC16 architecture) BoostLink Optimizing Linker Version 6.96 I switched the optimation on, but i think it should also work with optimation off. Any Idea? Greetings from Germany Coder
  6. Hello Pavel, Now i use 6.96! Result after that: cOut = 0x07; Result after that: Coder happy! Thank you very much! Coder
  7. Hi Pavel, Sorry, you wrote that you need it and i forgott it... IDE Version 6.6 CCompiler Version? how can i get it? No File-Version, no entry in the IDE, no idea... Helpfile BoostC.pdf Version 1.18 I translate it for a PIC16F876A Thank you and Greetings Coder
  8. Hello, i dont understand following problem: char c = 9; int i = 9; int iCode = 0xFFFF; char cOut = 0; if (test_bit(iCode,9)) set_bit(cOut,0); if (test_bit(iCode,c)) set_bit(cOut,1); if (test_bit(iCode,i)) set_bit(cOut,2); Result after that: cOut = 0x01; ??? Why word the first if (or the first test_bit - or the combination - don't knew) correct and the other not? Could somebody help? Thanks alot Coder
