Does the spiethconfig work for anybody?
I tested a lot, but i don't find the problem.
I insert printf commands in the code and get strange outputs. I change from picocom to putty, the same.

The command in short and long version:
spiethconfig -s 19 -i 23 -c 18 -e 0 -t 4
spiethconfig --miso 19 --mosi 23 --sck 18 --csenable 0 --interrupt 4
The output:
Invalid or missing Chip Select pin (0>128)
Command returned non-zero error code: 0x1 (ERROR)

I insert some printf-commands ( bold my changes):
            printf("argc: %d\r\n", argc);     

            if (result.count("s")) { miso_pin = result["s"].as<int>;(); }
            printf("MISO pin: %d \r\n", miso_pin);
            if (miso_pin < 0 || miso_pin > 128 ) { printf_P(PSTR("Invalid or missing MISO pin (0>128)\n")); return EXIT_FAILURE;}
            
            if (result.count("i")) { mosi_pin = result["i"].as<int>;(); }
            printf("MOSI pin: %d \r\n", mosi_pin);
            if (mosi_pin < 0 || mosi_pin > 128 ) { printf_P(PSTR("Invalid or missing MOSI pin (0>128)\n")); return EXIT_FAILURE;}

            if (result.count("c")) { sck_pin = result["c"].as<int>;(); }
            printf("SCK pin: %d \r\n", sck_pin);
            if (sck_pin < 0 || sck_pin > 128 ) { printf_P(PSTR("Invalid or missing SCK pin (0>128)\n")); return EXIT_FAILURE;}

            if (result.count("e")) { cs_pin = result["e"].as<int>;(); }
            printf("CS pin: %d \r\n", cs_pin);
            if (cs_pin < 0 || cs_pin > 128 ) { printf_P(PSTR("Invalid or missing Chip Select pin (0>128)\n")); return EXIT_FAILURE;}

            if (result.count("t")) { int_pin = result["t"].as<int>;(); }
            printf("INT pin: %d \r\n", int_pin);
            if (int_pin < 0 || int_pin > 128 ) { printf_P(PSTR("Invalid or missing Interrupt pin (0>128)\n")); return EXIT_FAILURE;}

and get the result:
argc: 7
MISO pin: 19
MOSI pin: 23
SCK pin: 18
CS pin: 255
Invalid or missing Chip Select pin (0>128)
Command returned non-zero error code: 0x1 (ERROR)

After that i change the sequence of the variables, the problems stay at the forth position. i saw that the out from argc stay at maximum 7 (in my opinion it should be 11).

Does it work for anybody?
If yes, what does is made wrong?

Thanks and best regards
