How to declare a string

[Rick Z]

I have a list of characters and trying to put them in a string.

char line[13]; /* Line buffer */

NRF_LOG_INFO("Playlist : %c", line[0]); this works displaying 1 character at a time

NRF_LOG_INFO("Playlist : %s", line); does not work displaying the 13 character as a string

What I am needing to do is create an array that has about 1000 x string(char(13)) and be able to read it back.

none of the string functions work I assume these are more c++

Thanks

NRF_LOG_INFO("Playlist : %s", line); does not work displaying the 13 character as a string

 If you use the placeholder %s, it will log all the bytes from the given address until it hits a NULL character. E.g the following (the characters are written as ASCII, convert it using http://www.asciitable.com/):

char line[4]= {0x48, 0x45, 0x59, NULL}; /* Line buffer */
NRF_LOG_INFO("%s", line);

Will print:

<info> app: HEY

If you have a NULL character in the middle of the string, it will only print the characters up to that point.

Best regards,

Unfortunately it does not print this but instead a garbage character is printed

Same as example i provided above which is essentially the same thing in your example

[Simon]

Can you provide your whole code? Or at least the source (.c) file where you assign values to line[].

The result back in log is as follow

<info> app: Playing PLAYLIST
<info> app: test 1
<info> app: I2S loopback example started.

next to test 1 is a weird character

    char line[4]= {0x48, 0x45, 0x59, NULL}; /* Line buffer */
    NRF_LOG_INFO("test 1 %s", line);
