RTOS/CC2650EM-7ID-RD: Help required in understanding Fontfixed6x8.c

Part Number: CC2650EM-7ID-RD
Other Parts Discussed in Thread: MSP430WARE

Tool/software: TI-RTOS

I am trying understand the contents of Fontfixed6x8.c, unable to correlate the font data with the actual characters. The snippet of which is pasted below:

static const uint8_t g_pucFontFixed6x8Data[760] =
{
  8,   6,   0,   0,   0,   0,   0,   0,   //Space

 8,   6,  32, 130,  8,   0,   2,   0,   //!

 8,   6,  81,  69,   0,   0,   0,   0, //"

 8,   6,  81,  79, 148, 249,  69,   0, //#  

..

..

..}

I understand that first two bytes corresponds to height and width, I am not clear on what basis the other bytes are derived for e.g (81,  79, 148, 249,  69,   0) for '#'.

Please clarify

    Hi Naveen,

    The graphics library is more or less borrowed from MSP430Ware, for the 430BOOST-SHARP96 boosterpack in particular.

    The above site is all I could find for documentation. The API documentation has a small section about fonts:  

    There is also a repository on GitHub where someone has uploaded converted open source fonts:

    Finally there is a post where a user describes making a font and has uploaded a conversion tool:
     

    If this doesn't help you I would suggest you post on the Tiva or MSP430 forum here on E2E as they would have more direct experience with this.

    Best regards,
    Aslak

    Hi Aslak,

    Thanks for sharing this information.

    I am yet to understand the correlation between these fonts data, actual character and pixel mapping.

    I will give another try by posting on the Tiva forum.

    Thanks again

    Naveen
