Version 11.9

Version 11.9

1. Fixed speed ladder display (was 100x speed)

Note: You should clear your old flight logs (reset it) as the new firmware uses a new structure and is incompatible with the old logs.

Re: Getting PPM-stream data out of the receiver

There are two kinds of failsafes in operation. The first type is used with receivers that stop putting out PPM when they lose the signal and go into failsafe. Many PPM receivers are like this - when you turn off the transmitter, the receiver outputs nothing or just noise. When this happens, the DOSD...

Re: Getting PPM-stream data out of the receiver

The DOSD+ can basically fly your plane for you, but in order to do so, it would need to control your servos. However, at the same time, you want to retain manual control over your plane. In order to do this, for example, the DOSD+ will need to know your stick inputs and as such you will need to feed...

Version 11.83

Version 11.83

1. Changed flight log dump to include more info

Note: This needs PC Commander 0.6.5 and higher to work correctly. You also need to manually reset your flight log as the old logged data is not compatible with the new firmware.

Re: Hacking Tektronix feature modules

I decided to re-build the dongle using the 24LC08 (SOT23-5 packaging) instead for a cleaner assembly and better fit. It worked perfectly:-

Some super-glue at both ends keep the board in place. I think this is it, I'm done with this hack.

Re: Hacking Tektronix feature modules

Now, I was wondering why it only recognized two of the four possible modules. I found that I had not zeroed out the second and fourth block. It appears that it is actually possible for all four modules to be recognized. So I fixed the programming and made sure all the blocks were zeroed out except f...

Re: Hacking Tektronix feature modules

Okay, I re-built using a 24C04 which was in a nicer MSOP8 package but turned out to have a quirk in that it ignores the A1/A2. So I wanted to try a 24C02 one, which is a real compromise but thought I'd give my original key a shot. As it turns out, it wasn't bad after all - it just needed a better co...

Re: Hacking Tektronix feature modules

Okay, we built the dongle and programmed the 2408 part but it seems that the scope voltage was too high for it. I guess I should order a proper 24C08 for the job.

Re: Hacking Tektronix feature modules

Physical mounting issues aside - each of the slots (up to four possible) have the A0 and A1 addresses hard-coded. Now, the 24C02 has 256-bytes so the A0 and A1 bits are pure chip-select pins. With the 24C08 they actually form part of the addressing (A8 and A9). So when the master sends the device se...
