What’s New?
… Read more...V2021-10-23 New: 3.2" 3.5" 5.0" 7.0" Start up behaviour. K3NG code v2021.10.19.04 or later REQUIRED. Nextion will now wait for gSC data to arrive from Arduino
How long does it take a Nextion / TJC HMI to power up, and be ready to receive data from your MCU?
If you’re relying on delays at the MCU side before talking to the HMI, this start up delay is important to get right, but best practice is to use proper two-way handshaking to let the MCU know when … Read more...

Adam’s Yaesu G-5500 stopped working 🙁
Meter lamps came on, but non responsive otherwise.
An open circuit diode was found, D3, so no 0V GND rail existed.
Easy to find using an ordinary DMM.
A better method of eliminating the voltage drop problem across R10 20 ohm 5W resistor (that feeds +12V to the External Control connector) was suggested by … Read more...

Adam walks you through how to fix ‘Crazy Mouse’ syndrome.
This is when your PC misinterprets serial NMEA GPS data as mouse data by the serial port enumerator, resulting in erratic mouse cursor activity.
Behringer X1222USB audio mixer Power Supply fails, again!
The SMPS modules fitted to these Behringer audio mixers are crap!
Fault symptoms include the appearance of no power to the mixer, except for the +48V LED being faintly lit when phantom power is turned on.
Adam explains what he did in this video:

In the next VK4GHZ Nextion for K3NG Rotator Controller NX4832K035 release (V2021-05-21) I’ll include the ability to toggle between the standard Big Az Gauge and your own custom gauge background.
This was inspired by the great idea of Andrej, S56VLV.
Switching to a custom azimuth background image is achieved with a long touch at the center of the Big Az … Read more...
