ThingSpeak

Verfolgen

Hi there, I am trying to implement the matlab function below (from a .m file) as a function block in simulink. The main gist is that it reads a string from thingspeak, then splits that string into data points. I am getting errors stating that most of the functions from matlab (split, thingspeak...) are unavailable for code generation. We cannot use the simulink thingspeak blocks as they only support numeric data, and we are processing large strings. What can I do to make this work? function [out0,out1,out2,out3,out4,out5,out6,out7,out8,out9,out10,out11,out12,out13,out14,out15,out16,out17,out18] = fcn() data = thingSpeakRead(1747813, "Fields",1,"ReadKey","M005PRKFNU6BQ3R3", OutputFormat="timetable"); disp(data) %defines delimiter delimiter1 = "*"; delimiter2 = ","; %converts timetable data into an array so it can be processed below dataConvert = table2array(data); %splits string into a 19x1 array stringSplit = split(dataConvert, delimiter1); %assigns location within array to variable val0 = stringSplit(1); val1 = stringSplit(2); val2 = stringSplit(3); val3 = stringSplit(4); val4 = stringSplit(5); val5 = stringSplit(6); val6 = stringSplit(7); val7 = stringSplit(8); val8 = stringSplit(9); val9 = stringSplit(10); val10 = stringSplit(11); val11 = stringSplit(12); val12 = stringSplit(13); val13 = stringSplit(14); val14 = stringSplit(15); val15 = stringSplit(16); val16 = stringSplit(17); val17 = stringSplit(18); val18 = stringSplit(19); %splits string a second time to a 1x2 array of shape [identifier,value] splitStringVal0 = split(val0,delimiter2); splitStringVal1 = split(val1,delimiter2); splitStringVal2 = split(val2,delimiter2); splitStringVal3 = split(val3,delimiter2); splitStringVal4 = split(val4,delimiter2); splitStringVal5 = split(val5,delimiter2); splitStringVal6 = split(val6,delimiter2); splitStringVal7 = split(val7,delimiter2); splitStringVal8 = split(val8,delimiter2); splitStringVal9 = split(val9,delimiter2); splitStringVal10 = split(val10,delimiter2); splitStringVal11 = split(val11,delimiter2); splitStringVal12 = split(val12,delimiter2); splitStringVal13 = split(val13,delimiter2); splitStringVal14 = split(val14,delimiter2); splitStringVal15 = split(val15,delimiter2); splitStringVal16 = split(val16,delimiter2); splitStringVal17 = split(val17,delimiter2); splitStringVal18 = split(val18,delimiter2); %assigns value to output variable to be used by simulink file out0 = splitStringVal0(2); out1 = splitStringVal1(2); out2 = splitStringVal2(2); out3 = splitStringVal3(2); out4 = splitStringVal4(2); out5 = splitStringVal5(2); out6 = splitStringVal6(2); out7 = splitStringVal7(2); out8 = splitStringVal8(2); out9 = splitStringVal9(2); out10 = splitStringVal10(2); out11 = splitStringVal11(2); out12 = splitStringVal12(2); out13 = splitStringVal13(2); out14 = splitStringVal14(2); out15 = splitStringVal15(2); out16 = splitStringVal16(2); out17 = splitStringVal17(2); out18 = splitStringVal18(2); end
