tinygs on ttgo t-beam v1.2

Hari — Wed, 24 Jul 2024 03:44:30 +0000

i was playing around with tinygs and t-beam while a go. just beeing amazed by oled displaying world map . i thought it’s just for fun flashed my t-beam using tinygs flasher. not hoping too much since my QTH was full of QRM. i began changing stock.default antenna with groundplane one and leave it for a night inside my house. and you know what? in the morning i checked the dashboard it was receiving from several satellles.

i wondered if i deploy external antenna outside i migh be get more satellites to receive.

QtSoundModem with usb serial for interface with persistent port.

Hari — Tue, 16 Jul 2024 11:02:47 +0000

I’ve been using QtSoundModem for several months now. one thing that bothering in mind was i’ve always have my serial port changed. ie: sometimes it’s ttyUSB0 sometimes it changes to ttyUSB1.i could just change from QtSoundModem gui to the right port. but it’s not practical. i found solution abd been using it for month to make my usb serial port persistent. kere’s the step:

lsusb 
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 013: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter
Bus 001 Device 012: ID 1b3f:2008 Generalplus Technology Inc. 
Bus 001 Device 011: ID 14cd:8601 Super Top 4-Port hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

sudo vi /etc/udev/rules.d/99-usb-serial.rules 
SUBSYSTEM=="tty", ATTRS{idVendor}=="1a86", ATTRS{idProduct}=="7523", SYMLINK+="PTT"

it will make serial tty with vendor id 1a86 and product id 7523(it’s QinHeng Electronics HL-340 USB-Serial adapter) symlinked to port named PTT.
now, even it changed to whatever ttyUSB0 or whatever number it always had the same symlink, PTT.

Add favicon to Ricardo’s LoRa_APRS_iGate’s WebUI

Hari — Mon, 08 Jul 2024 02:29:46 +0000

It is nice when you opened up your website and see tiny little icon beside the tab windows.
it’s somewhat like identity for your website. i have myself a blog and include favicon in it.
it’s my personal website’s brand, i say.

i see iGate’s WebUI has no favicon yet. i managed to tweak di code and added one.
basically it’s just adding our resource reference for favicon to file called web_utils.cpp.
added tiny favicon.ico in data_embed folder and patched few files.

here the link to my LoRa_APRS_iGate’s Ricardo forked repository.
https://github.com/HariHend1973/LoRa_APRS_iGate/tree/adding-favicon
all you have to do is clone my repository and do checkout to add-favicon branch.
the compile/flash.
i used platformIO on windows PowerShell(without vscode) and use ttgo t-beam.

git clone git@github.com:HariHend1973/LoRa_APRS_iGate.git
cd LoRa_APRS_iGate
git checkout adding-favicon
pio run --target upload --environment ttgo-t-beam-v1_2
pio run --target uploadfs --environment ttgo-t-beam-v1_2

there you go.

TTGO T-Deck tracker Mods

Hari — Mon, 08 Jul 2024 01:47:48 +0000

i’ve been playing around with Ricardo Richon Guzman tracker firmware.Specially on display. Ricardo’s coding style is excelent, even me is not professional programer able to follow.

i added some colors and frame on the T-Deck’s display. so far so good. there’s plenty space of improvement, it’s still not flawless yet. i’m not oficial maintainer, just a hobbyist and enthusiast of the tracker firmware though.

aprs.to trackdirect

Hari — Fri, 05 Jul 2024 00:59:28 +0000

by far, aprs.to is the best trackdirect website i’ve ever seen. once i built trackdirect too. but only basic one. since it need huge storage for storing all aprs stations, i discontinued the experiments.
