+ | * The new flukso uses SPI for communication, which the current hardware cant handle, but the fluksousb v2 can (currently in planning) | ||
* Why does fluksoUSB only show reasonable values when more than 1.000 Watts are connected? | * Why does fluksoUSB only show reasonable values when more than 1.000 Watts are connected? | ||
+ | * this is due to the offset-error from the ADC of the Atmel, which is higher when running at 5V compared to the 3V in the original flukso v1. | ||
+ | * To resolv the issue, it is necessary to aply a voltage of about 20mV(for one current clamp, 3 not yet tested) to the ground connector(black wire) of the current clamp. This can be done using a voltage divider(or potentiometer) connected to JP3 1st and last pins. I will provide more detailed instructions (with images) soon. | ||
