From bcd68f9e44a70c73bde08e612a28e413570dc039 Mon Sep 17 00:00:00 2001 From: James Bowman Date: Tue, 22 Sep 2015 22:43:56 -0400 Subject: sim: ft32: add character input port The FT32 simulator has character output, of course. This patch adds character input, which lets the simulator run interactive FT32 applications, e.g. language interpreters. --- sim/ft32/ChangeLog | 4 ++++ sim/ft32/interp.c | 2 ++ 2 files changed, 6 insertions(+) (limited to 'sim') diff --git a/sim/ft32/ChangeLog b/sim/ft32/ChangeLog index 988413f..29f661f 100644 --- a/sim/ft32/ChangeLog +++ b/sim/ft32/ChangeLog @@ -1,3 +1,7 @@ +2015-09-22 James Bowman + + * ft32/interp.c (cpu_mem_read): Call getchar when ea is 0x10000. + 2015-06-23 Mike Frysinger * configure: Regenerate. diff --git a/sim/ft32/interp.c b/sim/ft32/interp.c index 404683d..a20907c 100644 --- a/sim/ft32/interp.c +++ b/sim/ft32/interp.c @@ -169,6 +169,8 @@ static uint32_t cpu_mem_read (SIM_DESC sd, uint32_t dw, uint32_t ea) /* Simulate some IO devices */ switch (ea) { + case 0x10000: + return getchar (); case 0x1fff4: /* Read the simulator cycle timer. */ return cpu->state.cycles / 100; -- cgit v1.1
