From: kub Date: Sun, 17 Mar 2024 09:44:57 +0000 (+0100) Subject: core+platforms, revise pico pen handling X-Git-Tag: v2.00~90 X-Git-Url: https://notaz.gp2x.de/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c87e36d750d712d199df366cf7d74f778b34f1f0;p=picodrive.git core+platforms, revise pico pen handling the MSB in the tablet position register denotes pen on surface. add logic and a hotkey for handling pen not on surface. This allows for repositioning of the pen without the storyware reacting to it. --- diff --git a/pico/pico/pico.c b/pico/pico/pico.c index d190a940..99f21f4a 100644 --- a/pico/pico/pico.c +++ b/pico/pico/pico.c @@ -36,6 +36,8 @@ static void PicoResetPico(void) PicoPicohw.fifo_bytes = 0; PicoPicohw.r12 = 0; + PicoPicohw.pen_pos[0] = PicoPicohw.pen_pos[1] = 0x8000; + PicoPicoPCMIrqEn(0); PicoPicoPCMFilter(0); PicoPicoPCMGain(8); diff --git a/platform/common/emu.c b/platform/common/emu.c index 6895498c..d576b439 100644 --- a/platform/common/emu.c +++ b/platform/common/emu.c @@ -1050,10 +1050,9 @@ void run_events_pico(unsigned int events) switch (pico_inp_mode) { case 2: emu_status_msg("Input: Pen on Pad"); break; case 1: emu_status_msg("Input: Pen on Storyware"); break; - case 0: emu_status_msg("Input: Joystick"); - PicoPicohw.pen_pos[0] = PicoPicohw.pen_pos[1] = 0x8000; - break; + case 0: emu_status_msg("Input: Joystick"); break; } + PicoPicohw.pen_pos[0] = PicoPicohw.pen_pos[1] = 0x8000; } if (events & PEV_PICO_PPREV) { PicoPicohw.page--; @@ -1067,10 +1066,15 @@ void run_events_pico(unsigned int events) PicoPicohw.page = 6; emu_status_msg("Page %i", PicoPicohw.page); } - if (events & PEV_PICO_PEN) { + if (events & PEV_PICO_SHPEN) { currentConfig.EmuOpt ^= EOPT_PICO_PEN; emu_status_msg("%s Pen", currentConfig.EmuOpt & EOPT_PICO_PEN ?
