To change from Celsius to Fahrenheit
Go on SSH in expert mode.

Re: TGIF Lands in Pi-Star

Andy, Phil and others, Thank you for adding TGIF support to Pi-Star. Many of us were manually configuring this access. Several of my friends were unwilling to mess with their solid Brandmeister configurations to manually configure TGIF. Having this network built-in is a great addition. The nice thin...

Nextion on USB1 with DVMEGA Bluestack on USB0.

I was having trouble running PiStar on RPi3 with a DVMEGA/Bluestack on USB0 and Nextion on USB1. The DVMEGA runs fine without the Nextion. When both are plugged in the DVMEGA can't initialize and mmdvm host just cycles up and down. I have to actually configure the display to None to get the DVMEGA b...

Re: Nextion wired to a DVMEGA

I don't think you can use a Nextion screen directly wired to the DVMega. You can directly wire an OLED screen because it uses different pins. The DVMEGA and the Nextion use the serial port on the GPIO for direct wire. There's only one serial port so you can't use DVMEGA and Nextion at the same time ...

Re: LCD Support in Pi-Star

Yes, I just got this running. I used the 4 pins on the MMDVM HS Hat radio board. +5V Gnd SDA and SCL from the Hat to the display. I am using the 2004A display with the add-on board in the back that converts the I2C signal to drive the display board. So only these 4 wires between the HAT and the Disp...

Re: Nxdn not working

You need to be on the latest Pi-Star 3.4.16 Do an Update until it says already up to date, then do an upgrade. Repeat update/upgrade until you get to 3.4.16. You also need to be on MMDVM firmware 1.4.1 for the HAT. See https://www.toshen.com/ke0fhs/images/3-Pi-Star_firmware_updates.pdf For the duple...

Re: New PI-STAR user - RXoffset

Thanks for the help Keith. I did not know about mmdvmcal. I used that to display a carrier on my SDRPlay 2. The offset I needed matched the label on the radio board. At least I know how to see if I am close now. -Rick

Re: New PI-STAR user - RXoffset

Trying to understand the offsets better. Do the TX and RX offsets tweak the TX and RX channel frequencies? For example, does a +200 TX offset raise the TX freq by 200 Hz? Are these settings only to compensate for the manufacturing variations between boards and designs? It has been noted that offsets...
