I have found that the programs from the on-line book use have a different 'flavor' than the familiar microchip 'style': the use of res instead of equ, and use of macro-type commands that are a little startling at first. They also use language like, btfss 3,0 ;which translates to btfss status,carry ;a little clearer This might be a bit confusing to someone just starting out. I'm glad i Didnt come across it sooner, and had a little experience before trying to modifiy the routines. alice > Auracher wrote: > > > > Im serarching for an RS232 Programm that is easy and working on > > on an PIC16F84 with 4MHz and an MAX232. > > > > The samples I found in the web dont work! pleas send me some > > links or programmes that are working > > Need RS-232 routines for PICmicros without UARTs? > > Basic Stamp Compatible PIC Source Book/Disk On-Line Version Free! > Now converted to MicroChip Code, still available in Parallax Code. > > A collection of ready-to-use assembly language routines > based on the instruction set of the BASIC Stamp ¨ single-board > computer by Scott Edwards Electronics. > > Serin (receive data) receives a byte or string of bytes serially. > Optionally filters incoming data to a particular range of ASCII > characters, such as numbers. > > Serin (convert # data) converts a numeric text string received > by Serin into a 16-bit number. > > Serin (check qualifiers) determines whether text received by > Serin matches a table of qualifiers (password). > > Serout (send data) transmits a byte or string of bytes serially > > Serout (format # data) converts a 16-bit number into a counted > string for transmission by Serout. > > Includes useful schematics. > For MicroChip code: > http://www.dontronics.com/convert.html > For Parallax code: > http://www.dontronics.com/see.html > > Don McKenzie mailto:don@dontronics.com http://www.dontronics.com > > World's Largest Range of Atmel/AVR and PICmicro Hardware and Software. > Free Basic Compiler and Programmer http://www.dontronics.com/runavr.html
