* Allow GPIO 9 and 10 for waveform generation While most ESP8266 modules use quad-io mode for their SPI flash ROM, there are some which only use dual-io mode. Allow the unused pins (GPIO 9 and 10) to have waveforms generated on them. Should the user try this on a quad-io mode board, expect very bad things to happen. * Add variant for 8285 to init GPIO 9/10 The 8285 only has 2-bit flash IO, so the other two pins can be used as inputs (9/10). Set them to input to mirror the way other pins are set up. * Update waveform gen to only allow 9/10 on 8285 Update the common.h in both generic (remove TODO, it's done!) and the 8285 variant to make isFlashInterfacePin macro correct. Use that macro to disable pins 9 and 10 in the common, non-8285 case.
