-At a former employer, I had coded some embedded devices to spit out their bus address and current error code in morse code using the buzzer in the keypad. Saved me lots of time during initial debugging of new installations, then I'd just disable the buzzer before heading for home. (At least) on one occasion I forgot; years later a puzzled chief engineer calls me and says that his first officer had told him that E209 had a pending IGBT failure while they were discussing issues with the equipment we'd delivered over the din of the buzzers. Would that hypothesis have any possible merit? |
