<div class="markdown_content"><p>Hi Chris,</p> <p>Raspberry PI:</p> <p>think with a Pi2 or Pi3 this is sure possible (would apply an rt_preemt pacth or use a SD Image with already patched kernel)</p> <p>BBB:<br/> did not test this... it depends what else you application is doing<br/> If i find the time I'll give this a try.</p> <p>Sure for both you need for sure two Tasks - logtask - buffer - highspeed Task (500us)</p> <p>BR<br/> Edwin</p></div>

<div class="markdown_content"><p>Hello, </p> <p>Has anyone tested what the fastest cycle time you can achieve on the raspberry pi/Beaglebone with stability. I want to log somevariables to file at &gt;= 2000Hz (0.5ms). This is achievable with say Beckhoff controller but does anyone know if they have done this with Raspberry Pi or Beaglebone?</p> <p>Thanks, </p> <p>Chris</p></div>
