I was interested in this topic and sent for the hardware which just arrived, it took 2 months. I revisited the post HERE only to find that it stopped rather abruptly. Was there more work done on it.

Hi Palcal,

I stopped working on it, just because my high priority intention was to be able to display the ECG graph AND save the data to the SD card "at the same" time. But this is not easily possible I learned. I would have to use a second picoMite for storing the data or do some tricky circle buffering I am not able to implement via MMBASIC now, since I am a newbe and still learning the basic things. But if you just want to display OR log the data, everything does work :)

Maybe someone with more skill than me could use my code snippets and develop them further

Greetings
Daniel

Perhaps I'd better stop messing with PicoGAME and sort out the gerbers for the PicoMite Pear...

For a circular buffer can't you just use an array with a pointer? When the pointer reaches the last element+1 simply reset the pointer to zero. On each store into the array increment the pointer. That way you never run out of array. You just dimension it to what you might need. You can also plot a section of the array by plotting from element n to element n+width_of_plot.

Mick,

of course you are right. I've done this with C/C++ but I have so many projects running parallel including my main profession of designing PCBs that the time is limited. I have so much fun experimenting with the picoMite and the BASIC language /MMBasic dialect and this forum is a huge (!) help. In the future I will resume the work on the ECG. Until then I discover piece by piece the MMBASIC features, for example I try to built some pseudo (?) operating system with the picoMite to launch some of my applications and just for fun to learn and solve some of the limitations of BASIC by myself (no sprites, woraround with blit).

Greetings
Daniel
