I want to create a flexible signal shape that can be viewed using an oscilloscope by making a program. I am using an array to form the signal, such as {2048, 4026, 2048, 0}, where 2048 represents the flat line I want to adjust, 4026 represents the peak, and 0 represents the valley. I want to adjust the value of 2048 flexibly; for example, if I input x=3, it should output {2048, 4026, 2048, 2048, 2048, 0}. However, I am confused about how to use the for loop or if statements because I want to place the value in the middle. I need help with my code; please provide suggestions or possibly an example code.
That is the description of what I want to create, and here is my code.
The code that I commented on is the part that I want to make flexible.
#define NS 333
uint32_t Wave_LUT[NS] = {

Please help me, I really can’t analogize this anymore.
