Hi List, I've started playing around with the PIC10Fs. Of course I have already erased the calibration memory for OSCCAL. Now, how do I restore that value with a PicKit1 and MPLAB V7.31 ? Can I, rather? It won't do to write code for the appropriate address (like, MOVLW 0xC) because this address just doesn't seem to be programmed. In the settings for the MPLAB ICD2 I can choose to program calibration memory, for the PicKit there's no such thing. Another question: Using MPLAB ICD2 as a debugger with the PIC10Fs: what can I debug with it? Do I need a special adapter or even a special chip for that? Has anyone published code examples for the PIC10Fs? Is there any "PIC10F Freak Website" around? Googles finds lots of commercials ... Thanks, Christoph Oh, b.t.w.: as I'm just starting (again) with assembler: I've had a look at Farnell's PIC10F Quick Start Guide: what is the deeper sense of that: ORG 0x3FF ; I thought there were just 512 "bytes" ? why "3FF"? ORG 0x00 ; no code between the two ORGs: sense? -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
