GPIO number for spi1_cs1

SPI1_CS1 is GPIO3_PDD.00, It’s not PD.00,

Is there a rule for this type GPIO?

Thanks!

hello felixch,

please access pinmux spreadsheets from download center to review the default configuration.
you may also check Nano J41 Header Pinout for the look-up table of GPIO numbers.
thanks

Pinmux speadsheets does not contain gpio number info.

Checked Nano J41 Header Pinout & find out PortDD.0 IS 232.

So, For normal PortA to PortZ , The numer = Port Index * 8 + Bit index.
For PortAA, Port BB… The number = 26*8 + PortNN index * 8 + Bit index
PortDD.0 is 208 + 3 * 8 + 0 = 232.
