我是靠谱客的博主欣慰舞蹈，最近开发中收集的这篇文章主要介绍signature=6f5e2c2ca9ff7789e7ace6a5cd40e4d0,mame/mpu3.cpp at 6e46aed3ef86b87e02dbd13f00949ed020548c28...，觉得挺不错的，现在分享给大家，希望可以做个参考。

/* Notes 17/07/11 DH

added most other MPU3 sets

most fail to boot, giving the CPU a 'WAIT' instruction then sitting there

some complain about Characterizer (protection) and then do the same

a few boot to show light displays with no LED text

some display misaligned LED text

many run VERY slowly, even when the CPU is inactive (inefficient MAME timer system overhead?)

/***********************************************************************************************************

Barcrest MPU3 highly preliminary driver

based on MPU4 driver (see mpu4.cpp for credits)

Thanks to Chris Wren and MFME for documentation, particularly of meters and characteriser.
