The spi.begin(...) modifies the gpio, so you want to configure it afterwards -- though this shouldn't matter technically. </p> http://forums.leaflabs.com/topic.php?id=921#post-5698 Thu, 21 Jul 2011 14:07:33 +0000 josiah47 5698@http://forums.leaflabs.com/ <p>This does not work, pin 31 does not go on and off,<br /> HardwareSPI spi(2);</p> <p>void setup() {<br /> pinMode(31, OUTPUT);<br /> spi.begin(SPI_18MHZ, MSBFIRST, 0);<br /> }</p> <p>void loop() {<br /> digitalWrite(31, LOW);<br /> delay(1000);<br /> digitalWrite(31, HIGH);<br /> delay(1000);<br /> }<br /> if you comment out spi.begin line out it does work.</p> <p>Is it supposed to work like this? if so how does one turn and and off CS line to start data transmission from SPI device? </p>
