VK4GHZ Nextion firmware for the K3NG Rotator Controller receives an update dated 2021-10-23.

This update works in conjunction with Anthony Good’s, K3NG, latest release of rotator controller Arduino code, version 2021.10.19.04.

What’s New?

V2021-10-23

New: 3.2" 3.5" 5.0" 7.0" Start up behaviour.

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 the HMI is actually ready.… Read more...

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 Gauge.… Read more...

Both 3.5″ and 5.0″ Nextion touchscreens for the K3NG Rotator Controller receive an update.

This release also introduces a new “no frills” version for the NX4024_K032 3.2″ Enhanced Nextion HMI.

Change log:

V2021-05-10
Already!

3.2 " Fix: 
• Parking page - touching Return button showed another button image.

Both 3.5″ and 5.0″ Nextion touchscreens for the K3NG Rotator Controller receive an update.

Change log as follows:

V2021-04-06-01

Change:
• Splash page - timer 'tmrReadySC' (that waits xxx mS before expecting to see
  global system capabilities data from MCU) timing has been increased/relaxed.

Both 3.5″ and 5.0″ Nextion touchscreens for the K3NG Rotator Controller receive an update.

Change log as follows:

V2021-03-23-01

New:
• BigGauges page featuring larger Az/El gauges.
  Intended for manual (non tracking) operation ie; similar to using a real Yaesu G-5500 controller.
