Re: Voice (Megasound) Serial Update
Just checked the circuit of the HC1969 board. Unlike mine, he hasn't put a pull up resistor on the RESET signal, I have 10K. The internal pull up resistor is specified as between 30K and 60K. Maybe yours is closer to 60K and the reset signal does not go high quickly enough. The chip is specified as ...

Re: er9x development
Remember, you may have several mixes on a single channel. Each one has a weight, an offset, a curve/differential etc. These are all combined together to provide a channel information. THEN the limits and sub-trim are applied.

Re: Voice (Megasound) Serial Update
It takes longer to mount the SD card on FAT32, many more sectors to read. The test version effectively 'asks' the Megasound board "are you ready?" before starting to send a file. When you don't get the voice output, the board has stayed in the bootloader. The logic is: If this is a power o...

Re: Audio (voice) - Stock 9X PCB
Getting the starting point clear. You have replaced P3 with a rotary switch and fixed resistors that gives you the 5 values in your post? You want to decode these 5 values to have a different custom switch turn ON when you switch to each of these positions. You will then use these 5 custom switches ...

Re: Voice (Megasound) Serial Update
Yes, all OK. The 611818 is new in this version. basically, before I send a file I send an ABORT command. The Megasound board responds with the 61, followed by CAN twice 1818. I try this 3 times. If I don't see the CAN(s) then the board isn't talking to eepe. This should solve the single file problem...

Re: Voice (Megasound) Serial Update
More updates to try/check, this time including a linux version.
As always, save your existing version before trying these. I've added some more checking, including trying to get a definite response from the Megasound board before sending a file.

Re: Voice (Megasound) Serial Update
Eepe sends the ESC ESC sequence when sending a file so your problem relates to the serial. Since hyperterminal can send the ESC ESC sequence, and it is recognised I'm not quite sure why eepe is failing. Somewhere eepe is not using the COM port correctly - wrong port - wrong baud rate - wrong bits pe...

Re: er9x Upgrade Problem, Trims Switching Sides
I've checked the code, and the way I added this feature. It should default to NO crosstrims unless set, either deliberately or accidently.
What method did you use to upgrade the firmware? eepe or C9X?

Re: er9x development
The extended limit, that is also the endpoint adjust, does indeed 'stretch' or 'compress' everything, weight and offset included. The sub-trim, also on the limits page, is NOT affected by the limits. Sub-trim is the correct thing to change if you are centering a control surface, assuming you can't a...

Re: Voice (Megasound) Serial Update
Try using Hyperterminal on COM5. Connect up, switch the transmitter on, then press the ESC key twice. On the first press you should get E returned, on the second press you should get EF followed by carriage return, line feed and >. Just checking, the amod_last.hex you flashed is the one that is 53K ...

Re: Voice (Megasound) Serial Update
You are getting the sent data being echoed back when you have COM3 selected.
To send multiple files, when the dialog appears to select the files, simply select more than one, select the first file, then hold Ctrl down when selecting others.

Yes, the FM modes are different trims. I'm trying to keep things reasonably simple, and make sure all facilities fit as standard. There are 5 flight modes, 0 - the default, and 1 to 4, the switch selectable modes. If you set the value to the letter, then the trim is specific to that mode. If you set...

Re: Voice (Megasound) Serial Update
I may need to do some specific testing to try to see if I can sort this out. I've done some investigating. There is code in the bootloader that forces it to stay in the bootloader if the receive data pin is held low at power up. Unfortunately, to work properly, this relies on the watchdog timer to b...

Re: Voice (Megasound) Serial Update
HC1969: What FUSE settings do you program into the Megasound boards? In particular, do you enable the watchdog as always on?
Moska: I don't know if you can get at the board easily, but can you test that pad 8 is actually connected to the processor pin 31?

Re: eepSKYe
Yes, I have to update them both together! I'm (slowly) working on merging them into a single program. The eepskye source files are in a sub-directory from the eepe source files. One of the source files is now common to both programs!

I notice you used COM5 this time instead of COM4 you used before, I assume the serial device has moved ports! There may be a connection problem on the Megasound board.

Re: Voice (Megasound) Serial Update
After typing 0 (zero not the letter O) and space, the board should enter bootloader mode and stop giving voice output. You can try repeating the sequence 0 and space. If this still doesn't stop the voice output try: Switch the Tx off. Hold pad 7 on the Megasound board at ground (0V). Switch Tx on an...

Re: Voice (Megasound) Serial Update
I was just going to suggest that. I've also got an idea why the first file might fail. Eepe sends two ESC bytes to switch the Megasound board into serial update mode. When it switches, the board has to re-mount the SD card into the full FAT file system. If this take too long, it might miss the start...
