Rumble issues in Windows CE titles about maplepad HOT 5 OPEN

Sega Rally 2 test from 9/17/22:

Absolutely baffling... So in Sega Rally, going into the settings, selecting a rumble strength and pressing A will make the game send a SetCondition command to the rumble pack. But with Maplepad, the SetCondition command never gets sent when I press A.
In fact the game instantly freezes
how the controller could make the entire game loop freeze is beyond me

MaplePad's SendControllerStatus packet (A press) looks the same as the HKT-7700's in this capture. I did see some spurious spikes on the data lines after turning off the glitch filter in DSView. Maybe the next step is to capture this particular transaction with the scope and make sure this isn't a SI issue or a bug in the PIO engine.

the problem is that the current implementation of maple in pio is very crap and misses some packets, you need to completely rewrite the pio rx module and get rid of state_machine.c
advice from an experienced programmer, if you want to do it well, write your code, other people's code always contains errors

Thanks for the heads up! I'm no longer working on this project, but feel free to open a PR if you want to contribute

I'm currently busy with my project of connecting USB keyboards/mouses to DreamCast.
initially I also used this library to process maple, but when I tried to connect a PS3 controller, I encountered the same problems as you, in the end I had to write PIO RX from scratch and change PIO TX so that it would work stably
P.S. I use only one core for maple, the second core is used for USB processing, and I do not use DMA for maple transfers

Sounds like your rewritten Maple Bus core works well. If it's abstracted enough to merge into MaplePad you're welcome to open a PR.
