Revert to actual BF font, now that DJI fixed G2 and newer

It would be worth adding to the release notes that Goggles V2 will have some issues. Also that Goggles 2 and above will need to be on the latest firmware.

Hi @mmosca ,

I think you may have forgotten a few icons that can be used:

LQ symbol:

        case SYM_RSSI:
            return DJI_SYM_RSSI;

        case SYM_LQ:
            return DJI_SYM_LQ;

// RSSI
#define DJI_SYM_RSSI                    0x01 // RSSI bars
#define DJI_SYM_LQ                      0x7B // RSSI bars with LQ on top

Compass symbol:

The betaflight speed icon also looks alittle bit like half of a compass:

        case SYM_DEGREES:
            return DJI_SYM_HEADING_DEGREE;

        case SYM_HEADING:
            return DJI_SYM_HEADING;

#define DJI_SYM_HEADING                 0x70 // Betaflight speed symbol (looks like compass symbol)
#define DJI_SYM_HEADING_DEGREE          0x08 // High circle looks like degrees icon

There might be a few others as well.

I agree with LQ. But using speed as compass is too wrong.

[dzaro-dev]

INAV doesn't have a speed symbol anyway, might as well use it for something.

Here's the code snippet:

    case OSD_UNIT_METRIC:
        if (_max) {
            tfp_sprintf(buff, "%c%3d%c", SYM_MAX, (int)osdConvertVelocityToUnit(vel), (_3D ? SYM_3D_KMH : SYM_KMH));
        } else {
            tfp_sprintf(buff, "%3d%c", (int)osdConvertVelocityToUnit(vel), (_3D ? SYM_3D_KMH : SYM_KMH));
        }
        break;

[MrD-RC]

That is a gauge. It would be fine for speed or RPM. But makes no sense for compass. Just using it for the sake of it is not the correct approach.

Also, we should not be changing osd.c. These should be symbol changes only.

[sensei-hacker]

I pretty much agree - LQ yes, and thanks for pointing that out!

Speed for heading? Nah. Though I wouldn't be too upset if that was done.

I can understand "may as well use it for something", but
"may as well use it for something" would also apply to marking your home location with a skull 💀.

[MrD-RC]

I believe symbols 0x7D and 0x7E are Km and Miles respectively. I know they're commented out. But is it worth using the correct symbol for completeness?

[mmosca]

What line are you referring to? The efficiency ones are not available in the DJI/BF font.

The distance 0x&d and 0x7E are used in SYM_KM, SYN_MI

[mmosca]

case OSD_UNIT_METRIC:
    if (_max) {
        tfp_sprintf(buff, "%c%3d%c", SYM_MAX, (int)osdConvertVelocityToUnit(vel), (_3D ? SYM_3D_KMH : SYM_KMH));
    } else {
        tfp_sprintf(buff, "%3d%c", (int)osdConvertVelocityToUnit(vel), (_3D ? SYM_3D_KMH : SYM_KMH));
    }
    break;

Not going to more extra code for this kind of stuff.
