May be it's better to formulate my question in a different way.
We know that all SPI settings are determined by the Arduino SPI Control Register (SPCR).
The question is:
How can I read out values for each of the specifc bits and store each of them into a different variable?
In SPI these bits are:
SPIE, SPE, DORD, MSTR, CPOL, CPHA, SPR1, SPR0
I'd like the values to displayed on screen and then be put into string-variables named like:
v_SPIE, v_SPE, v_DORD, v_MSTR, v_CPOL, v_CPHA, v-SPR1, v_SPR0.
Displaying the values of SPCR on screen is not a problem, except the leading zero's are omitted. The command is Serial.print(SPCR,BIN);
How can I avoid leading zero's?
How can I read each bit separately?
Help and advice is appreciated.
Thanks.
