Re: MMDVM_HS_HAT Held in reset

I have identified the issue with the MMDVMHSHAT in question. I cut the PCB track connecting the 10K pull-up resistor to the reset input of the STM32 processor on the MMDVMHSHAT board, having removed the 100nF capacitor to make sure that wasn't leaking and the resistance of the reset pin to ground wh...

Re: MMDVM_HS_HAT Held in reset

Yes, I did try an update and after that even a pistar-mmdvmhshatreset wouldn't make the Hat board work. However I have solved it! Looks like the defaults for the GPIO lines have changed in the Pi updates. So I have now put in the /boot/config.txt file the following line gpio=21=op,dh This sets the g...

When it boots the reset line from the pi to the Jumbsoot board stays a a logic 0 and holds the modem in reset. If I issued a pistar-mmdvnhshatreset from a SSH command window everything works. It is...

Removing ON7LDS Driver

I’m thinking of trying the ON7LDS driver on my Jumbospot using 2.4” Display. I currently do not use the driver. How easy is it to remove it if I find I wish to go back to the standard driver?

Phil

Raspberry Pi WiFi

Hi, I’m a new user for pi-star using a Pi Zer W with a Jumbospot hat. On the implementation of pi-star is the pi WiFi disabled from sleeping. From memory the standard desktop pi image has the WiFi going to sleep after inactivity. In the case of using ssh/web sever to access the pi in pi-star I hope ...
