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/capacity.rs | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'examples/capacity.rs') diff --git a/examples/capacity.rs b/examples/capacity.rs index e50f929..00cec34 100644 --- a/examples/capacity.rs +++ b/examples/capacity.rs @@ -38,8 +38,10 @@ const APP: () = { debug::exit(debug::EXIT_SUCCESS); } - // Interrupt handlers used to dispatch software tasks + // 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 UART1(); + fn SSI0(); } }; -- cgit v1.2.3
