Algorithm 1 The microcontroller-based main program

Initialize the microcontroller and configure the output pins;
Set the length N of sequences, the Number M of interpolation;
Set intermediate variables step_1,2,3,4, temp_1,2,3,4 and value_1,2,3,4;
while true
Set four sets of (a_i, b_i, x_i_,0, y_i_,0) (i = 1,2,3,4);
for i = 1 to N
//system equation
x_1,i+1 = 1 − a₁|x_1,i| + y_1,i; y_1,i+1 = b_1×1,i;
…
x_4,i+1 = 1 − a₄|x_4,i| + y_4,i; y_4,i+1 = b_4×4,i;
//interpolation
step₁ = (x_1,i+1 − x_1,i)/M; … step₄ = (x_4,i+1 − x_4,i)/M;
for j = 0 to M − 1
temp₁ = x_1,i + j∙step₁; value₁ = (temp₁ + 15)*4096/30;
…
temp₄ = x_4,i + j∙step₄; value₄ = (temp₄ + 15)*4096/30;
Transfer the value_1,2,3,4 to TLV5618;
end
