button-target.h H300: Don't read the button ADC as long as no button is pressed, utilising the PCF50606 accessory detect feature. Ported from X5. 2006-10-29 13:48:57 +00:00
system-iriver.c H300: (1) Use DMA for LCD updates, with auto-aligned line reads. Speeds up LCD updates by ~ 75% at 11MHz and 45MHz. Only ~ 11% speedup at 124MHz due to (2). (2) Less aggressive LCD transfer timing at 124MHz. With the previous timing, slightly corrupted display contents was reported, and with DMA transfers at least 4 waitstates are needed to make updates work at all. * A table in system-iriver.c shows settings for all integer multiples of the base clock frequency (info for developers, not yet complete). 2006-11-02 20:50:50 +00:00
