Re: (RPI) Changing the tty to an external device and validating functionality

I will take a look at this further, I found a new problem this morning when checking the PTT, I have active low COS, which is tied to the inhibit pin, looks like I need to rethink that approach as the logic is inverted but I dont see an option to toggle the inhibit logic in the dashboard. I also not...

Re: (RPI) Changing the tty to an external device and validating functionality

Can you recommend some places to get started with configuring the mmdvm and the MD380 rigs to talk to each other. Been fighting this for a bit now and I cant get anything in the logs or dashboard that even looks like the radio is talking to the mmdvm controller. I have confirmed I have audio from th...

Re: (RPI) Changing the tty to an external device and validating functionality

I fired up a second board and checked the logs, I suspect that was something I did the blipped it. I think I might have been testing the programming function through openocd around the same time.

Re: (RPI) Changing the tty to an external device and validating functionality

I think everything is working now, I jumped up to the 4.1RC4 so I could pull down the changes from the rpi admins and now I get this in the log monitor Starting logging, please wait...

Re: (RPI) Changing the tty to an external device and validating functionality

I found why you are seeing the same uart potentially. Just found this is the /boot/config.txt file on the 4.1RC4 image. same chipset, just on spi instead of i2c

Re: (RPI) Changing the tty to an external device and validating functionality

Just a quick update on this topic. I got the new crystals today and have it installed. I am now using 3.6864 MHZ which should be a perfect crystal for all uart speeds under 115200 down to 9600. Bad news for the night is that I can no longer even load the device into the system, it just barfs when it...

Re: (RPI) Changing the tty to an external device and validating functionality

Thats really crazy that you are getting bit errors like that, I'm not sure what could be causing that. Is this coming right off the UART board and into the USB->UART adapter? I2C shouldn't have any problems going that slow, I know on drone flight controllers that use STM32's, they are running i2c a...

Re: (RPI) Changing the tty to an external device and validating functionality

This is a prototype 1 board that I am getting turned on for the time. per this page, i could be getting errors as high as 5% due to the master crystal being at 12.288 MHz which doesnt divide down nicely. I have proper devices on order from digikey that should be here Thursday or friday that I will f...

Re: (RPI) Changing the tty to an external device and validating functionality

I finally broke out my USB to UART dongle and got it setup to sniff the output of the MMDVM UART going from the pi to the stm. The codes I am getting are 0xF0 vs 0xE0 (bit 4 error) 0x83 vs 0x03 (bit 7 error) 0x80 vs 0x00 (bit 7 error) this looks suspiciously close to the right codes you provided, bu...
