From 1aa0e17df7c325a41de8cf8a57f52ed853f08bf3 Mon Sep 17 00:00:00 2001 From: "John Wilbert M. Villamor" Date: Fri, 24 Apr 2020 19:01:28 +0800 Subject: Refined toolchain instructions, organized examples, added automatic retry for CdRead(), added FIOCSCAN ioctl in psxsio TTY driver, added tty and console examples. --- examples/system/console/main.c | 284 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 284 insertions(+) create mode 100644 examples/system/console/main.c (limited to 'examples/system/console/main.c') diff --git a/examples/system/console/main.c b/examples/system/console/main.c new file mode 100644 index 0000000..988b428 --- /dev/null +++ b/examples/system/console/main.c @@ -0,0 +1,284 @@ +/* + * LibPSn00b Example Programs + * + * Text Console Example + * 2020 Meido-Tek Productions / PSn00bSDK Project + * + * This example demonstrates a tty text console implementation for gameplay + * sections, or sections with continuously updating graphics.
