Description Luke Kenneth Casson Leighton 2018-07-30 13:24:56 BST 
BSV auto-gen from spec

also multiple maps, selectable via an external pin at boot time (not to be put onto the pinmux!!!)
Comment 1 Luke Kenneth Casson Leighton 2018-08-03 06:28:59 BST 
src/bsv/peripheral_gen/gpio.py:

    def mkslow_peripheral(self, size=0):
        print "gpioslow", self.peripheral, dir(self.peripheral)
        size = len(self.peripheral.pinspecs)
        dflt = "%s" % ("0"*size*2) # XX TODO: read default from config
        return "MUX#(%d) mux{0} <- mkmux(`b%s);\n" % (size, dflt)+ \
               "GPIO#(%d) gpio{0} <- mkgpio();" % size

src/spec/microtest.py:

    config = {'muxdefaults': {'A': '001010' # binary (2-bit)?
                             }
             }
    ps = PinSpec(pinbanks, fixedpins, function_names, config)

maybe there are better ways to spec this, e.g. pass in a dictionary of muxer defaults {"A": {0: 0b01, 5: 0b10 } } which are turned into the binary string, later?
