when my two 9x (ATMEGE 128) are connected to the USBASP programmer, the displays are also blank.

Add the MULTIPY mix to the e.g. throttle channel = channel 3
CH3 100% Thr
* 50% P1 Fix Offset 50 NoTrim !! Multiply

According to the position of P1 your CH3 output will be limited between 0 an 100%

My pro ran 2 1/2 hours without a problem
Display ans sound worked permanently

Reinhard

btw
Wouldn't i be an idea to power down the radio when you have Inactivity timeouts and low battery warning?

0x1e9801 seams to means ATmega 2560 ????

Reinhard

Can you please update Github also ?

Reinhard

does this also happen with a fresh created new model?

Reinhard

Sometimes it helps flashing, when the cable between programmer and the processor of the radio is as short as possible.

Searching the forum, I found suggestions of -B100 up to -B10000

Reinhard

You may be right. and there is a difference, as you say. According to the help display from Preferences in eePe -b <baudrate> Override RS-232 baud rate -B <bitclock> Specify JTAGS/STK500v2 bit clock period (us). I don't know which one is the one to be used. I only remember that a low number was sugg...

One mor possibility. Try to slow down the communication speed of AVRDude In opentx companion in settings - Configure Communications... in the "Extra Arguments" field use the parameter -b xxxxx This overrides the baudrate that is used. (if I remember correctly then the lowest value I have read of is ...

There normally is a small smd resistor pack between the processor and the output pins of the board with 4 resistors (8 pins) that is marked with "101" that is 100 Ohm. These are (normally) ok. The problematic resistor packs were marked 102, that is 1kOhm, IIRC Another possibility for problems someti...

Glad it is working and thanks for the feedback

@ozphoenix I succeded to get a version of my Split program that is working on Win10. The only culprit is, you must install it (14 files totally). The zip file contains a setup.exe that you must run to install the program. The program offers a simple user interface where you can select the input file...

@ozphoenix I just have written a small program that reads a raw log file and formats it in a way like this, readable with a normal text editor 7E 98 10 01 F1 61 00 00 00 9B 7E 98 10 04 F1 59 00 00 00 A0 7E 22 10 00 02 00 00 00 00 ED 7E 16 7E E9 10 00 03 40 75 57 77 68 7E B7 7E 00 10 00 01 1E 46 00 0...

I flashed your document.eepe file onto my radio. This is what I did to get the voice running with your Eeprom setup: Power on the radio in maintenance mode, that is, power on with left horizontal trim left (and released) . You will shortly see a message of "Hardware menu enabled" In Radio setup - ha...

But on Amazone you can find a cheaper one. Though I dont know the shipping cost. https://www.amazon.com/ChipQuik-SMD1-Leaded-Temperature-Removal/dp/B0019UZP7I/ref=pd_sim_328_4/131-1541285-4467364?_encoding=UTF8&pd_rd_i=B0019UZP7I&pd_rd_r=57976a97-0bc3-11e9-b34a-211282c114f8&pd_rd_w=IddDp&pd_rd_wg=ni...

João, that's correct

And I found a solution for OpenTx also.
It works with the sticky function

ch7 = ch7 Weight(+100%)
+= ch9 Weight(+10%) Switch(!L1)
+= ch9 Weight(-10%) Switch(L1)
ch9 = Thr Weight(+50% Offset(50%)

L1 Sticky L2 L3
L2 a > x CH7 99
L3 a < x CH7 -99

I found a solution with ERSky/ER9x that I believe does what you are looking for. I dont know if opentx has a similar function (Latch with set/reset). I set up a logical switch (L6) as a latch with a SET (L1) and a RESET (L2) condition. It is set, when the output channel, in my example ch07, is > 99 ...

I found a description of how to check and how to restore the firmware of the 16U2 chip. So the code is obviously not hardcoded in this chip. https://www.instructables.com/id/How-to-Restore-the-Arduino-UNO-R3-ATmega16U2-Firmw/ And reprogramming of most of the Arduinos can be done with an USBASP progr...

That was the question that was answered in that post.

Does anyone have the ERC12864-2 adapter board that flygear was selling? I need one or where I can get a 30pin top to bottom ffc adapter.

I'm not sure, but I think it does.

Reinhard

This connector could possibly help you

on my radios EEpe reads the fuses as
extended 0xFF
High 0x81
Low 0x0E

Reinhard

As you "might" have a battery problem, did you calibrate the battery voltage? (Radio setup - diagnostic Ana - right value in the bottom line, has to be set to the voltage you measure at the battery with an instrument)

Reinhard

If you can read data from the radio to the PC then e.g. do a read fuses (screen will stay open so you can see what it did!)

The first step is to read the device signature (of the cpu).
0x1e9702 is M128
0x1e9602 is M64

Reinhard

If the posted code mod does that I’ll give it a try. That code snippet was the original code. So to have that special output (landing light) inverted the HIGH and LOW have to be exchanged with each other like in this modified code. if (state && !curLandingLight) { digitalWrite(LL_PIN_LIGHT, LOW); /...

I’m trying to use a get or transistor as a led driver but it inverts the pulses. My work around was to use 2 transistors to cancel the pulse inversion. If the inversion of the signal is your only problem, why not change the code to get an inverted signal ? A short view into the mentioned code shows...

Thanks,
that is what I was afraid of.

Since short, I have a 9xr Pro (latest fw) with an STM32.. Multi protocol module (Banggood). I also have a little heli, where I don't know, if it's protocol is suported or not. Is it possible to write a script, that, step by step, tries to bind to every available protocol (and option) without manual ...

João, it did. :) There came just another idea to my mind. Last time when I tried the update of the module with the radio, I used the exported code that I compiled with the IDE option "upload via serial inc. Bootloader" When the module is already flashed with a boot loader, should I then compile with...

Thanks, I already had seen that page but the pattern of my LEDs did not correspond with any of the described patterns. Except, green off means no power at the module. When I tried to flash the module, I had it removed from the Tx and the Vin pin connected with the 3.3v pin of the USB/TTL converter. ...
