Hello,
I can't find backlights for turnigy 9x anywhere. I searched on aliexpress and found this display with 2 types of backlight. In the reviews, even the customer put the display on the Turnigy9x board.

Has anyone tried this type of backlight with 3 or 5 diodes?

Ok, I'll glue it. Thanks!

Hello,
where can i buy such buttons for Turnigy 9x?
I can't find it anywhere, is it possible that they fit from another transmitter (frsky, etc.)?

Replace the module with a multi protocol JP4IN1 and everything will be fine.

I fixed the module, flashed with another baud rate . The version is "multi-stm-opentx-aetr-noinv-v1.3.1.59.bin". And now I have telemetry 8-) Is it good for the resistor between the processor and the module to be 100 ohms or bring back the 470 ohms ? And finally: What value should it be Ra...

I think the bootloader is broken. But how to flash it with USB-to-TTL as it does not have the necessary pins TX,RX,GND,VIN. It has the 5 holes but they are spi,mosi,miso,sck,rest

Due to a bad cable, interrupted while flashing. And now I can't flash. What to do. Writing MULTI-Module via serial [1/3] Erasing flash memory ... done [2/3] Writing bootloader ... failed! I also tried an Arduino Probing serial port COM5 for STM32 in BOOT0 mode ... stm32flash 0.4 http://stm32flash.go...

Thanks!

I have progress




I only want the receiver voltage, but it shows 0. Where could be the problem?

Hello, I try to set up a telemeter mod, but without success. Atmega2561 I will be grateful for a little help. 1. First I tried the module - it binds with the receivers (FS-iA6B or iA8) and works. 2. Then I done a telemetry mod - cut the tracks on the 2 and 3 pin before the resistors (200ohm) and wir...

Unfortunately, the calibration is for all models.
I don't know why with different modules it shows different voltage. The difference is not 0.1-0.2V to ignore it, but 1 volt.

Ok, thanks anyway.
And what programmer should I buy from e-buy / aliexpress for 1-2-3$ with which 2561 can be programmed without problems?
Or make a cable for a quick connection to an Arduino?

EDIT: I will buy Arduino nano for $1.89

Thanks!

I have 1 more problem.
With the FM module it shows the wrong battery voltage by 1V more than with the original module. It is measured with a multimeter.
The voltage is calibrated with the original module.
Can I do a voltage calibration on a new model or is it for all models.

I connected ATtiny44 to Arduino and made a backup. Where can I find newer firmware?

Done, tested and works well on 72Mhz and 2.4Ghz

Yes, but what is the inverter for? I have connected the PPM signal directly.

Today I wanted to test the transmitter before a flight. At 72MHz, when I press the trim several times quickly, the transmitter stops working - voltage anomalies and nothing works. After a restart, everything is fine until I press the trim again. https://i.imgur.com/S2WhLK7.jpg https://i.imgur.com/Zp...

If I remember well from that time a bunch of usbasp used old firmware that had an issue with that, so you needed another programmer to reflash the programmer before it would work right. Where can I get new firmware to fix ATtiny44? Could be better https://i.imgur.com/XbytiDs.jpg Flash with Arduino ...

I have USB to RS232 Serial TTL (PL2303) and Arduino UNO R3 (ATmega328P)
Will it be possible to flash with either of them? And how to connect?

EDIT: Can I use an Arduino like here to flash ATtiny44? And what firmware?

Which is the cheapest option.

I changed the chip, flashed the fuses, flashed the firmware and the check failed. Otherwise, everything works. https://i.imgur.com/2Akw0Gi.jpg https://i.imgur.com/lEJeUwg.jpg https://i.imgur.com/x1ScjsI.jpg Attach firmware downloaded from the transmitter.

The antenna cable is very long, is it a problem to push it into the module box or can it be cut to the required length?

+1 for the same question

I have several receivers at 72mhz and I want to use it with one transmitter. I tested with the FM module and everything is fine. https://www.youtube.com/watch?v=0huUQ1nFEfg&feature=youtu.be The original antenna will not be used. The multiprotocol module has an antenna. I can put the telescopic a...

Not in stock in local stores
Are all chips from China fake? Is it a problem if I put one from aliexpress/ebay?

OK thanks.
How would larger RAM memory affect?
And are there any changes other than changing the chip?

No, I want to use the original antenna as it is on the top of the transmitter, not on the back of the module. And I ask if it is safe to unsolder the antenna cable from the old module and solder it to the new one.

Is it safe to solder the original transmitter antenna to the multiprotocol module?
Or the original antenna of the multiprotocol module must be used?

Hi, I want to upgrade the processor. Changing the chip is not a problem for me. I want to replace it with Atmega128, but I wanted to ask Atmega2561 is there any advantages? And I also wanted to ask if ordering a chip from aliexpress would it be ok? The price of such a chip in a local store is about ...

Thanks! I will order one.

With multiprotocol module can it remember more than one AFHDS 2A receiver?
