The Mikrobus header is a 0.1" pitch 2x8 header which supports the Mikroe Click board ecosystem. This header features 3.3V, 5V, SPI, GPIO, ADC, PWM, a UART, and PWM. All IO are 3.3V tolerant.

By default all of these headers default to their non-gpio functions. These can be changed in the FPGA syscon register 0x08. For example: 

# Make all mikrobus header pins GPIO:
peekpoke 32 0x50004008 0xF0

# Set only SPI to GPIO:
peekpoke 32 0x50004008 0x10

  1. ↑ This signal does not require a mux to use as a GPIO or ADC. To use the ADC signal the GPIO should be an input which is the reset default.
  2. ↑ This signal is pulled high, but your specific click card may require a specific reset duration.
