Nextion / TJC HMI Power Up Timing

October 5, 2021 by admin

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...

Yaesu G-5500 Ground Rail Fault & Better Voltage Drop Fix

August 4, 2021 by admin

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 Mike, WB8CXO, and implemented. … Read more...
