pulseio.PWMOuts share duty cycle values when many of them are created #1106
Description
I tested it with the following code on my custom board:
=== ROWS = (
=== pulseio.PWMOut(board.R8, frequency=200000),
=== pulseio.PWMOut(board.R7, frequency=200000),
=== pulseio.PWMOut(board.R6, frequency=200000),
=== pulseio.PWMOut(board.R5, frequency=200000),
=== pulseio.PWMOut(board.R4, frequency=200000),
=== pulseio.PWMOut(board.R3, frequency=200000),
=== pulseio.PWMOut(board.R2, frequency=200000),
=== pulseio.PWMOut(board.R1, frequency=200000),
=== )
===
>>> ROWS[4].duty_cycle
0
>>> ROWS[6].duty_cycle
0
>>> ROWS[6].duty_cycle = 500
>>> ROWS[6].duty_cycle
274
>>> ROWS[4].duty_cycle
274
Where the pins are:
{ MP_ROM_QSTR(MP_QSTR_R1), MP_ROM_PTR(&pin_PA14) },
{ MP_ROM_QSTR(MP_QSTR_R2), MP_ROM_PTR(&pin_PA19) },
{ MP_ROM_QSTR(MP_QSTR_R3), MP_ROM_PTR(&pin_PA05) },
{ MP_ROM_QSTR(MP_QSTR_R4), MP_ROM_PTR(&pin_PA17) },
{ MP_ROM_QSTR(MP_QSTR_R5), MP_ROM_PTR(&pin_PA11) },
{ MP_ROM_QSTR(MP_QSTR_R6), MP_ROM_PTR(&pin_PA04) },
{ MP_ROM_QSTR(MP_QSTR_R7), MP_ROM_PTR(&pin_PA10) },
{ MP_ROM_QSTR(MP_QSTR_R8), MP_ROM_PTR(&pin_PA00) },
