Dear all tone() is not supported. If I compile a Sketch with tone() I get error message: - error: 'tone' was not declared in the scope There is...
But less often jitter... Also when I stop xserver I have less often jitter...
When I Shutdown Linux it's still the same output jitter...
Andrea, thank you for testing with oscilloscope! Please, do me a favor and change "Persist Time" in the oscilloscope to 30 seconds (or better...
When I disable the timer GPT I have no more output jitter! But Linux does not work any more. GPT_CR&=(~(1U<<0)); Any comments on this?
It's now running from I-TCM and still the same...
Thank you!
Hi Is there a way to use tcm ram from a sketch? Thank you for helping me!
See the sketch with IOMUX configuration: #include <mqx.h> void setup() { // iomuxc #define GPIO4_SPEED (3U<<6) /* 0..3 = 50mhz, 100mhz,...
Thank you, I've already tried this. It's still the same.
Thank you! Good idea, is it possibel to do that in a sketch?
If we solve this "udoo neo" comes par with Beaglebone concerning Realtime...
Thank you for the code... My delay() can be unstable, I don't care about that. What I'm pointig out is the time between _int_disbale() and...
I disable interrupt to do my output for a defined time...
[ATTACH] This is how the output signals looks like...
Thanks for the answer! Below the new sketch. The output is faster put still has 400ns jitter. #include <mqx.h> void setup() {...
Hi For driving some micro valves I need to generate pulses (no pwm!) with bitbanging. With the oscilloscope I see the pulsewidth with 500ns...
Ok, I will do it with attachInterrupt() and detachInterrupt() for testing. 1) Does the interrups all have the same priority? 2) Have you planned...
Hi Andrea We got our first NEOs today and I've start with testings. Our MCU based controler for realtime applications needs for some products big...
Hi UDOOs The functions Interrupts() / NoInterrupts() are not supported as of July 2016. How do you handle this for critical time sensitive code...
