2. The second step is to transmit the data. The bootloader programs on a page of 128 bytes basis when it is possible. The host must take care that: • The data to program transmitted within a CAN frame are in the same page. • To transmit 8 data bytes in CAN message when it is possible 3. To start the
because the measurment voltage is only between 0.3 V and at most 1.3 V, the polarity doesnt matter. When the part is connected, you should not touch it during the measurement. You should put it down to a nonconducting pad if it is not placed in a socket. You should also not touch to the isolation of wires

However, we can now remove the two while loops | since the ISR only ▯res when a byte is received, and only one byte is sent after each reception, we can guarantee that both checks are now redundant.

deviation of the actual ADC’s transfer function from the ideal straight line at zero input voltage.

With positive offset errors, the output value is larger than 0 when the
another criteria for a successful enhancement of the resolution is that the input signal has to vary when sampled. This may look like a contradiction, but in this case variation means just a few LSB. The variation should be seen as the noise-component of the signal. When oversampling a signal, there should
