#147652 - glue a cheap EEPROM Responding to: ???'s previous message |
Erik Malund said:
glue a cheap EEPROM to the sensor and store the calibration data there. That way the sensor becomes replacable. Many forms of use of that data can be chosen e.g. values for compensation in the uC (been there, done that) maybe now that they are abundant and cheap it could be values for some digipots on the board. PPS 'my' scale sold 620,000 units last I heard (I am, as many have figured out, not making scales any more) 620000 units , Great!. I wont ask propritory details neither those should be told as its against norms. But no two sensors share the same calibration data , that will also require software finetuning each sensor.Can we get rid of this with some automatic feature. APC |
