Here's one for the Piclist - I can't answer this since I don't have access to a PICSTART. Our compiler produces hex files in a format that I believe is generally known as INHX8M - i.e. two bytes per PIC word, with the upper bits of the second byte unused. MPLAB has no problems with this. We also produce a .COD file. What does the PICSTART accept? -----Forwarded message from pakton@ozemail.com.au (Paul Thompson)----- > I am using the PICSTART -16B1 (firmware version 2.0) to blow a windowed > 16C71 but > it doesnt understand your intel hex file output. > I dont know whether the incompatibity lies in the firmware or the the MPS16B > program. > Is there another output file format that I should be using? -- Clyde Smith-Stubbs | HI-TECH Software, | Voice: +61 7 3354 2411 clyde@htsoft.com | P.O.
