I recently participated in a Matlab course and was wondering how to readout a teensy over serial and how to search directly on temperature values ; current values and plot them against the time stamp from themicroprocessor Millis on the screen.
I looked up some code, but I can’t program at the moment due to no access of Matlab on my work/Homeoffice or try it out.
This the pseudo borrowed code, I know that I am in the right direction,
info = instrhwinfo('serial'); if isempty(info.AvailableSerialPorts) error('No ports free!'); end s = serial(info.AvailableSerialPorts{1}, 'BaudRate', 9600); open_data = fopen(s) line = fgetl (open_data) scan_line = sscanf (line, '%f,%f,%f) (depending on the output) % it returns as too many argument open_data = fopen(s)
Timestamp = millis();
Timeraw =char(sizeof(line)); Timemeasured=char(sizeof(line)) TimeTeensy=insertBefore(line,‘ms‘,Timemeasured));
%LineT= "78c 72c 64c 66c 49c"; degreeSymbol = char(sizeof(line); Tempraw = insertBefore(line,‘c‘,degreeSymbol)
%LineA= "3,1A 72A 64A 66A 49A"; Currentsymbol = char(sizeof(line); Ampere= insertBefore(line,‘a’,Current)
Plot(Time,T_TC1, linespec, Time, T_TC2, linespec2, Time,T_TC3, linespec, Time, T_TC4, linespec); Hold on;
Plot(Time,TEC_A1, linespec, Time, TEC_A2, linespec2, Time,TEC_A3, linespec, Time, TEC_A4, linespec);
Plot(Time,, linespec, Time, TEC_A2, linespec2, Time,TEC_A3, linespec, Time, TEC_A4, linespec);
Hold off Legend(); Xlabel(,); YLabel(,);
Many thanks for your time and your quick review
