GPIO on robotic cape

[ith...@gmail.com]

Hi, on BB blue there were gpio sockets, they do not exists on the robotic cape. The cape is not also "thru", i.e. no sockets for another cape. How can I use GPIO when the robotic cape is plugged? There is a socket SPI1.1 with pins SPI11_MOSI, SPI11_MISO, SPI11_SCK, SPI11_SS1, can there be reutilised as GPIO? If yes, how to translate their names to values for gpio_export etc.?

Guessing from this https://github.com/StrawsonDesign/Robotics_Cape_Documentation/blob/master/SD-101D_header_pin_table.ods, gpio1[17], gpio3[17] are free. Is it also the case for gpio3[21] if IMU is not used? I need 3 x GPIO.
