I have built a circuit (poptronics & PE Jan 96) by Robert Gotchall. the asm file from gernsback has errors mostly due to a missing include file that is different from the std microchip file that was not in the download. There are also errors such as portb defined as port_b etc. and some registers that are not defined. Does anyone have one of these working and can supply the error free code?? or any other solution?? such as Robert Gotchall are you out there??? The project I am doing is an autoranging cap tester that uses a pic 16c57 as its main component I can't believe the mess gernsback is in. there are always PAGES of error corrections for the prev. issue projects and articles and when you try to use the links on their home pages to contact them they either go to some poor stranger who has no idea what you are on about or they are returned undeliverable. Anybody else have the same problem?? I however, have elected build this project and the code with some 300+ errors is beyond my scope to repair Thanks Wil Reeder Vancouver Canada teachtech@bc.sympatico.ca
