WAIT GPIO n for n > 32 and when using gpio_base = 16
- fix bug: pioasm was spilling bit 5 of arg2 into arg1 - make pio_add_program flip bit 5 of a WAIT GPIO instruction if gpio_base is 16 Note: pioasm will encode only the bits 4-0 of arg2 (the GPIO number), however it does indicate whether 0-15 means 0-15 or 32-47. This can only be fixed up when loading the program, and indeed once the GPIO base is known. pio_can_add_program and friends already detected the cases where this was impossible

There was a problem hiding this comment.
Ok. After staring at this for awhile it looks good. We really should have an example of using this. Any suggestions?
