16f628a Simple Programs
May 24, 2011 - There is a C compiler for MPLab, do you have that? If you do, then you should just be able to go into the menu and select your specific PIC and compile for that chip. 2012-5-22 Programming the PIC 16F 16F628A and 16F1828 Reply to Thread. As you can see the code is very accessible, where to do that came task in assembler is nowhere near as simple or as easy to write. The PICKIT2 still programs a good range of chips, some of them you have to use the separate PICKIT2 application to program, but that's.
What's the physical configuration of your MCLR pin? Your config has MCLR enabled, so if you aren't supplying VCC to the MCLR pin(pin4/RA5) then you're basically holding down the reset button. Change your config statement to: uint16t at 0x2007 CONFIG = CPOFF & LVPOFF & BORENOFF & MCLREOFF & WDTOFF & PWRTEON & INTOSCOSCNOCLKOUT; In more general advice, I have found it useful to explicitly disable all the config options I'm not using. It prevents things like being bitten by MCLR, but it also forces me to read more of the datasheet and learn more of the microcontroller's features. I also see from your comment that you're using SDCC 3.3. As of this post, SDCC 3.5.5 is available. The current SDCC manual recommends using #pragma config to set configuration bits, as the method used in your example is deprecated.
Programs And Features
Here's an excerpt from the manual: 4.6.17 Configuration Bits Configuration bits (also known as fuses) can be configured using one of two methods:. using #pragma config (see section 4.6.6), which is a preferred method for the new code. Example: #pragma config CP0=OFF,OSCS=ON,OSC=LP,BOR=ON,BORV=25,WDT=ON,WDTPS=128,CCP2MUX=ON #pragma config STVR=ON. using ‘code’ and ‘at’ modifiers. This method is deprecated.
Ubc Programs
Possible options should be ANDed and can be found in your processor header file. Example for PIC18F2550: #include //Contains config addresses and options static code char at(CONFIG1L) configword1l = USBPLLCLOCKSRCFROM96MHZPLL21L & PLLDIVNODIVIDE4MHZINPUT1L &.; static code char at(CONFIG1H) configword1h =.; static code char at(CONFIG2L) configword2l =.; //More configuration words Mixing both methods is not allowed and throws an error message ”mixing CONFIG and CONFIG directives”. So, using the method recommended in the SDCC manual, your config block would be: /. CONFIGURATION Bits./ #pragma config CP=OFF,CPD=OFF,LVP=OFF,BOREN=OFF #pragma config MCLRE=OFF,PWRTE=OFF,WDTE=OFF #pragma config FOSC=INTOSCIO.
