Radiomaster Zorro Telemetry Script: Does not display images

[marcrupprath]

Hello ,
see last entry here:
https://www.rcgroups.com/forums/showthread.php?2180477-LUA-scripting-Technical-discussion/page229#post45440615

This script:
**-- Telemetry script, round.bmp is stored in the IMAGES folder.

local function bg_func()
end

local function init_func()
end

local function run_func()
lcd.clear()
lcd.drawPixmap(0, 0, "/IMAGES/round.bmp")
lcd.drawPixmap(74, 0, "/IMAGES/round.bmp")
lcd.drawPixmap(148, 0, "/IMAGES/round.bmp")
end

return {run=run_func, background=bg_func, init=init_func}**

Will not work either in EdgeCompanion similation nor on my Zorro Transmitter
It just creates an empty screen but does not show the bitmap located on SD Card folder"root" \images

Question is why ?

Edge Campagnion shows logmessage like:
298730ms: f_open(C:/Users/Administrator/OneDrive/2025/zorro_red/IMAGES/round.bmp, 1) = 00007fffa0288a90 (FIL 00000082aa3fecd0)

Where: C:/Users/Administrator/OneDrive/2025/zorro_red, is "root" folder for symulaton

As you can see on the example images, it seasm that it runs fine on Taranis ?
MAybe it was made with OpenTX

Note : have uploaded "round.bmp" used in code as jpeg, because i cant upload bmp here-

Thanks in advance

Images for B&W radios like the Zorro (with 128x64 pixel displays) have to be 1bpp, not greyscale or indexed color.

[marcrupprath]

Yes indeed, same as for the taranis in the example.
Yestion is why scripts works on taranis and not for Zorro, esspecialli not in the simulation

[philmoz]

Wide screen B&W radios have a 4bpp display - the image is indexed color (greyscale), so it will not work on your radio.

Thank you that solves the problem, bsides the fact that bitmaps must not exceed 1/2 screen width
