The diode is on the back board, near where the wires from the charge socket connect.

Mike

Looking at your suggestion for a software change, if you are at zero throttle and you move the stick to full, then the slew rate will be at the highest rate and the acceleration from zero to full speed will be at the fastest rate. I don't think that would simulate the flywheel approach, I would thin...

This appears to be a very specific requirement. Probably best to try to make it work without changing the software.
I'm considering what is possible using just mixes.

Mike

If setting throws, then endpoints are "best". You adjust each end independently, while weight will adjust both sides at the same time.
In either case, trims should give you 25% of the available throw.

erskyTx or openTx firmware?

Mike

Did you succeed in flashing erskyTx to the radio (without errors)? If so, does it all appear to work correctly? R222 is fine. When you say using bootloader mode didn't help, what actually happened? Did the radio start OK in bootloader mode (power on with the horizontal trims held inwards)? If so, wh...

The RPM input on the hub is connected directly to a processor pin. The three connections are 0V, signal, and 5V. I assume the signal is just pulses from the original, optical RPM sensor. Ideally keep the signal in the range 0-3.3V, although I believe the processor pin is 5V tolerant.

Mike

This is odd as Companion appears to be using SAM-BA to access the radio. Normally you would use the bootloader. Please try powering the radio on with the two horizontal held inwards, this should start the radio in bootloader mode, then connect the USB cable. Companion should then use the bootloader ...

To use ACCESS software in a Rx you have to have an ACCESS transmitter. The ACCESS protocol has not been reversed so you cannot use a multi-protocol module with an ACCESS Rx.

The firmware to which I linked is ACCST V1, and should work with the multi-protocol module.

Mike

Update posted. Are you only using the multi-protocol module or are you also using a FrSky Tx module? If you go to the download page for the XM receiver, at the bottom is: "History firmware DOWNLOAD (not compatible with v2.x.x)". Click on that and you will get the V1 firmware for the XM Rx. This appe...

OK, I found a bug in erskyTx related to handling multi telemetry where the lead byte (e.g. 0x7E for FrSky) is not present while it is present from a real FrSky module. In handling that, I misread the status packet length causing every other status packet to be missed. I have the fix for that and the...

At some point the multi firmware changed so it sends the selected protocol and sub-protocol names to the radio. erskyTx also has these names built in, and also in the file "Multi.txt" on the SD card. The names from Multi.txt override any built in names. When you change the protocol or sub-protocol, ...

The registration of a Rx should be common to all models.

Mike

I assume you are running openTx (and not erskyTx).
Set up a logical switch to:
AND SCv SCv duration(20.0), then use the logical switch to control channel 8.
When you move SC to SCv, the logical switch will turn on for 20 seconds.

Mike

The original stock module (Flysky FS-TM002) works fine, as does the more recent module (AFHDS2A type), although for this later module you may need to change the PPM polarity to get it to respond.

Adding the -B 10 won't hurt.

Mike

You probably need to slow the programming clock down, this is done by adding -B 10 to the AVRDUDE command. In eepe, go to the Burn|Configure menu and put -B 10 in the extra arguments field. Also, I recommend going in to the Burn menu and selecting "Set Fuses to Protect EEPROM", otherwise the the EEP...

Pity, the '128 version is able to do more, including having twice as much EEPROM for model storage, which is why the EEPROM needs a re-format.
You need er9x for M64-FrSky, this handles the telemetry.

Mike

That should not be necessary. The firmware for the m64 works perfectly on the m128. Do you really need to stick to openTx? It was forked from er9x originally, and on the 9X I don't think it was ever really that much different to er9x. Since openTx support for the 9X stopped, I have enhanced er9x qui...

Support for openTx on the 9X transmitter stopped some years ago.
I am still maintaining er9x for the 9X transmitter.

Mike

I think it power option is handled somewhere in openTx, I found the code a couple of days ago! Having got the "latest" ACCESS protocol spec. a couple of days ago, I should be able to get "capabilities" from the receiver, I'll need to get that first, then display the receiver options that are availab...

First check if you connect the USB to your computer with the radio power OFF, you get a STM Bootloader device appearing.
Then try the instructions here: https://opentx.gitbooks.io/manual-for-o ... shing.html.

Mike

On a side note, why does the receiver options screen have pin mappings anyway. Is it only for receivers with PWM pins? Should it even be there for an SBUS only receivers? Probably not, and from the log files I can see it isn't sending the channel mapping data. I've done a change to make the display...

If you power the Tx on holding the two horizontal trims towards the centre, do you get the bootloader?
If not, then try connecting the USB with the radio powered off, do you get a device appearing on the PC called a STMbootloader?

Mike

Very odd the display is garbled, neither of my two ACCESS radios do that. Please generate a new (raw) logfile: 1. Enable raw logging. 2. Turn logging on. 3. Call up the receiver options screen, then exit it, then call it up again, then exit it. 4. Now call up the Internal Protocol Options, exit, cal...

Is the Receiver Options screen still "garbled"? I wondered if the last change to fix the telemetry may have fixed that as the data is sent to the Tx using the same protocol as the telemetry. I've just added the telemetry power and the SPort/FPort options to the ACCESS Rx options in the source code. ...

No, you will still need an inverter for the SPort telemetry. On the AVR processor, it is not really possible to invert this in firmware.

Mike

I'm not sure what you are asking. erskyTx is available for the RMTX16S, just flash the .bin file to the radio. If you use eepskye, you may customise the splash screen, it is embedded in the .bin file.

Mike

Yes MegaSound serial is included (er9x-frsky-sv.hex).

Mike

OK, go here: https://openrcforums.com/forum/viewtopic.php?f=7&t=4676 and download eepskye5.zip from 12-Dec-2020. Install this by extracting all files from the .zip file, keeping the directory structure, to a suitable directory. Now copy the eepe.exe to this same directory. It should run from there. ...

New version posted (for the X7ACCESS), I think I found the problem!
