SDK • Re: Pico W noob, tried to modify httpd example, but no linkage - need to generate pico_fsdata.inc

Code:

import osdef generate_fsdata(directory, output_file):    with open(output_file, "w") as f:        f.write("// Generated file containing HTML data\n\n")        for root, dirs, files in os.walk(directory):            for file_name in files:                file_path = os.path.join(root, file_name)                with open(file_path, "r") as file:                    data = file.read()                    array_name = file_name.replace(".", "_")                    f.write(f"const char {array_name}[] = {{\n")                    for char in data:                        f.write(f"0x{ord(char):02x}, ")                    f.write("\n};\n\n")if __name__ == "__main__":    generate_fsdata("web", "pico_fsdata.inc")
