From 8e636f0d1286cf905518022d42adf9624bed44df Mon Sep 17 00:00:00 2001 From: Danilo Bargen Date: Fri, 26 Jun 2020 23:46:09 +0200 Subject: Examples: Clarify extern section Some beginners are confused about the "extern" section, so I added an explanation comment to all examples. Furthermore, using the UARTx interrupts when UART is actually being used in the same example may be confusing, so I changed them all to SSI0/QEI0. --- examples/not-sync.rs | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'examples/not-sync.rs') diff --git a/examples/not-sync.rs b/examples/not-sync.rs index 57b18d7..a7eaac8 100644 --- a/examples/not-sync.rs +++ b/examples/not-sync.rs @@ -36,7 +36,10 @@ const APP: () = { let _: &NotSync = c.resources.shared; } + // RTIC requires that unused interrupts are declared in an extern block when + // using software tasks; these free interrupts will be used to dispatch the + // software tasks. extern "C" { - fn UART0(); + fn SSI0(); } }; -- cgit v1.2.3
