It fixed the problem for me. I made a similar #define for __write.</p> <p>That was good --- got further along the compile without error until an "undefined reference to 'systick_uptime_millis'" in usb_serial.cpp. systick.h is included in usb_serial.cpp which does have systick_uptime_millis defined and initialised.<br /> But at the line number 74 of usb_serial.cpp there is no 'systick_uptime_millis' at all, only a 'millis'.</p> <p>millis is defined in wirish_time.h, and wirish_time.h is indeed included in usb_serial.cpp</p> <p>So there should be no error relating to 'millis' or 'systick_uptime_millis'. ( how compiler appears to detect 'systick_uptime_millis' in place of 'millis' is itself a mystery.</p> <p>Am beginning to think that the systick.h and systick.c that go with MapleCoOS are maybe too far behind the current release to be adjusted successfully. </p> http://forums.leaflabs.com/topic.php?id=14268#post-29500 Sun, 08 Sep 2013 19:17:35 +0000 ala42 29500@http://forums.leaflabs.com/ <p>This should do what is needed<br /> #define __read(p) (*(volatile unsigned int*)(p)) </p> http://forums.leaflabs.com/topic.php?id=14268#post-29497 Sun, 08 Sep 2013 14:50:43 +0000 seandeg 29497@http://forums.leaflabs.com/ <p>Hi All,</p> <p>Am trying out the blink .pde program from <a href="http://akb77.com/g/mcu/maplecoos/" rel="nofollow">http://akb77.com/g/mcu/maplecoos/</a><br /> Have placed the MapleCoOS directory under libraries in the IDE.<br /> Have replaced the systick.c and systick.h in hardware/leaflabs/cores/maple with the alternative dot c and dot h files from <a href="http://akb77.com/g/files/media/systick.c" rel="nofollow">http://akb77.com/g/files/media/systick.c</a> and <a href="http://akb77.com/g/files/media/systick.h" rel="nofollow">http://akb77.com/g/files/media/systick.h</a></p> <p>Getting compile error<br /> "Settings\Admin\Desktop\maple-ide-0.0.12-windowsxp32\maple-ide-0.0.12-windowsxp32\hardware\leaflabs\cores\maple\/systick.h:52: </p> <p>error: '__read' was not declared in this scope"</p> <p>I can not find where __read comes from --- can not find it at any scope.
