It's a prototype and I've been going through churn-n-burn development to pin down some coefficients. If I've programmed it enough times to hit the write endurance limits (DSPIC parts are only 1k write cycles) - assuming it verifies ok - is it likely to lose bits after I ship it? It'll only be a couple weeks of acceptance testing. -Denny -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
