The reference manual will come in handy but the handler you need is:</p> <blockquote><p><code>.extern "C" {<br /> . void __irq_spi1(void) {<br /> . // Insert code here<br /> . }<br /> .}</code></p></blockquote> http://forums.leaflabs.com/topic.php?id=9906#post-21664 Sat, 15 Dec 2012 02:13:34 +0000 mh555 21664@http://forums.leaflabs.com/ <p>PS. This is restricted to D5. D15 works well even with the SPI interrupt active. </p> http://forums.leaflabs.com/topic.php?id=9906#post-21663 Sat, 15 Dec 2012 02:12:28 +0000 mh555 21663@http://forums.leaflabs.com/ <p>Hi!</p> <p>An interrupt on D5 (attachInterrupt(D5, ...)) works fine, but when there is an active SPI interrupt (spi_irq_enable(SPI1, SPI_TXE_INTERRUPT);) it stops firing. The SPI interrupt works as expected. Is this a hardware related issue? Or some libmaple bug? Or my mistake? </p>
