pilo Posted May 14, 2003 Report Share Posted May 14, 2003 hi!I found a new PIC18f programmer :http://members.naspa.net/djs/software/pic18f.htmlwhich is a plug on the parallel port... And the woftware works under linux.I think I can use it without any care?thanks! Quote Link to comment Share on other sites More sharing options...

TK. Posted May 15, 2003 Report Share Posted May 15, 2003 Hi Pilo,the problem with this programmer is, that it uses the low-voltage programming mode and therefore allocates pin RB5, which - once the mode has been enabled - cannot be used for any other purpose anymore. Consequentialy you cannot drive a LCD module, which requires RB5 as data pin.Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...

pilo Posted May 15, 2003 Author Report Share Posted May 15, 2003 hum... But, I put the pic on the programmer, then put it in the midibox... Because I use RB5 in the programmaing sequence then i can't use it anymore??!!?? Maybe I should download the PIC18F datasheet....I want to make a stand-alone programmer (not in the midibox)... ???

Posted May 15, 2003 Report Share Posted May 15, 2003 Hi,Because I use RB5 in the programmaing sequence then i can't use it anymore??!!??yes!From the PIC18F452 datasheetThe High Voltage Programming mode is always available, regardless of the state of the LVP bit, by applying VIHH to the MCLR# pinWhile in low voltage ICSP mode, the RB5 pin can no longer be used as a general purpose I/O pin.Best Regards, Thorsten.
