chaotic spi in audioplayer #1

Closed LovelyA72 closed 2 years ago

LovelyA72 commented 2 years ago

Hello, I am currently trying to make audioplayer work on a PFS154. However, the example does not work at all. After probing on the SPI line I found that not only the timing is a mess, the padauk is driving the MISO pin which it needs to be listening to instead of driving.

SDCC changed assembler syntax for operations with IO.

All projects been updated with commit 0a82dfbfca3656f6f5e5c17c818249734a20f67c . They now require a recent SDCC (>=4.1.10) to be compiled.
