Interesting, I can reproduce that sound on my M64 system. The sound is clearly related to the haptic output (I don't have a haptic fitted to my radios) as I changed from HAPTIC3 to HAPTIC2 and the number of "blips" reduced.
Odd that it doesn't happen every time.
Are you certain someting is on the beeper signal (seen with a oscilloscope for example)?

Mike.

I will try to measure in oscilloscope tomorrow. I'm sure it comes in the buzzer line, I remove the beeper wire and it does not happen anymore.

My other TX, which has the W020, uses the piezoelectric in series and controlled by a bc547, also the same occurs. But as it is connected to the BC547, it is possible to hear the noise in the piezoelectric.

See my other video with TX with W020.W020 Piezo noise

Mike, in the future is it possible to configure PC0 (PB3), PC4 (PB4), PG5 (PB5) and PB7 (PB7) as extra switches on / off?

Marco.

I think I can see what might be causing the problem.
I'll do a change to the source code and test it, but it may have to wait until tomorrow.

PB7, PC0, PC4 and PG5 are all available as switch sources, Are you asking for more switches as in "PB3" and "PB4" push buttons?

Mike.

Yes!! more Switches.

I think I have fixed the beeper sounding when haptic is running problem, I've just posted a mbtx3.zip on the first post with the fix in.
Adding some more switches as PB3 and PB4 is not a quick job, and, because of the extra code needed, I don't think it should be added to a M64 board.

Mike.

mbtx3 no more noise !!

Thanks Mike !!!

Hi Mike ,


Is it later possible to compile a version for the M64?

Marco.

The files mbtx-frsky.hex and mbtx-frsky-sv.hex (serial voice) in the zip file are for the M64.
Do you need a version that is without the frsky (telemetry) mod?

Mike.

Yes. My friend uses TX without mod. He wants only the serial voice module.

I'll try to build such a version of "V2", it may take a bit of time.

Ok, take your time.

Hi Mike,

I opted to make the mod AIL an THR (FRSKY).

in M64 frsky-sv, I am giving the message "BAD EEPROM", I can not configure trim, pb1 and pb2 by hardware mode (V1 and V2).

The first time your run er9x after flashing between V1 and V2 the EEPROM will show as bad.
If the EEPROM shows as bad every time you flash the firmware, check the fuse settings "Preserve EEPROM".

The M64 does not have enough flash to include all those hardware settings. You have to read the EEPROM into eepe (or eepeV2), make the settings there, then write the EEPROM back.

Mike.

Hi Mike ,
For M64, Frsky SV.
Bad EEPROM occurs after recording the EEPROM by program V2. Identical to the problem I mentioned earlier.
So I can not configure it.

This worked OK for me. My M64 radio doesn't have serial voice, it is on parallel, I just flashed it with mbtx-frsky.hex, let it create the EEPROM, then I could read it OK with eepev2, modify it and write it back.

Make sure you go into settings on eepev2 and change the processor type to M64 in TWO places.

Mike.

If you are still having a problem, use the option in eepeV2 to read the EEPROM to a file, then zip the file up and post it for me to look at.

Mike.

It was a TX from a friend, I had to give it back. I did not have time to test.


Tks !!

Marco.

Hi Mike,

My friend has a transmitter with atmega64, I installed the serial megasound. I can not get into Hardware to configure PB1 (ext1) and PB2 (ext2).
For both MBTX and R821. The trim (TH) in the Megasound board don't work to.

OBS.continues to appear the "BAD EEPROM" for MBTX.

Tks

Marco.

Is the FrSky mod also done on this radio?
I'll try to post some updates tomorrow, I'll run some tests on them first.
When using the M64, you can only set hardware options from eepeV2, there just isn't enough flash to include it on the radio.

I went back to the previous version "EEPEV1" and now PB1 (EXT1) and PB2 (EXT2) working. It should be some bug in version 2.
I have not yet made the modification to the FRSKY (keys) ... I just installed the serial audio.

Will you have the bug fix "minutes and minute"?

Tks!!

Marco.

I've posted an updated mbtx (er9xV2).
I tested this on a M64 with frsky mod (telemetrez) and a parallel megasound board.
Using the included eepeV2 I was able to read and write the EEPROM, and change the setting of PB1.
It does include the minutes/minute voice fix for 1 minute remaining.

Eepev2 continues with the error "bad eeprom" i used mbtx-frsky-sv.hex
i use M64 Fr sky mod (djt serial) and a serial megasound

tks,

Marco

See this print...data for EEPEV2 is 2017, november.

Marco.

That is the version of eepeV2 I was using.
I have just built a new test version and posted on the first post.
Please try reading the EEPROM from your radio with this one. If you still get a "Bad EEPROM Error", try using the "Burn" menu option "Read EEPROM memory to File", then post the resulting .hex file for me to look at.

Mike

Hi, Mike

I did so, formatted the eeprom when the message "bad eeprom" appears, shortly after I loaded the eeprom in the EEPEV2 and then edited PB1 and PB2, timers, megasound and etc. And now it works. The working eeprom is attached.

Tks,

Marco,

"The following on the MegaSound module:
XPB0 (EXT1 on V1)
XPB1
XPC0
XPD2
XPD3 - used for LV trim
XPD4 - used for LV trim
XPD7 (EXT2 on V1)
Note: Some of these may need the Megasound firmware to be updated to use them."

I can't see XPD7 or EXT2 in the EEPE2.

I think "LV trim" does not work.

The LV trim mod is routing the left vertical trim switches to PC0 and PC4 (I didn't add this feature). It is not supported on the M64 for flash space reasons. If you have serial Megasound, then the left vertical trim switches need to be routed to the Megasound board.

I'll look into the switch configuration options on eepeV2 later tonight.

Mike
