Flashing without a programmer.

[jtroutt19]

Is it possible to flash this TX without the USB programmer. I ordered this TX and it will be here monday and am wanting to put the ER9x FW on it. I would like to be able to do it without the USB programming stick. Thanks for any help you guys give.

If you're talking of the 9X/9XR, no.

Alrighty well then Ive decided to build my own. I am a 1st year almost 2nd year EE student so im still a noob when it come to this stuff. We have not gotten into embedded systems yet. But my skills with building circuits is A1. With all the parts i have lying around all i need is the ATMEGA chip. With that being said which should i choose the ATMEGA8 or or something different. Also how do i go about programming the chip on the self built programmer. Thanks for the help btw.

Perhaps, replacing Atmega with a pre-programmed one will do the trick. But I didn't see any offers of Atmegas pre-programmed with er9x, yet.

So you have to find a USBasp or similar. It will also let you use eePe, which is great to set up models and test your settings before applying them to real models.

You need a programmer

Easiest is to get a USBASP, but you could look here:
http://www.lancos.com/prog.html

Which might get you started if you have a serial port available on your PC.

LOL....So the USBASP is a incircuit programmer i take it. MUHAHAHA. damn programmers. I need a programmer to program the programmer that is going to program the programmer! lol.....Will a arduino board work for programing the atmega8?

Why yes out of one of the 6 computers I have one of them has a serial port on it. Thanks for the webpage!

[jtroutt19]

Oh and the TX is the flysky fs-th9x, which is the same as the turnigy 9X

If you have one, I think some people already used an arduino as an ISP programmer.. Forgot about that one
But why an atmega8? with he arduino you could probably program the radio

I dont have on not yet... being after christmas and a college student I am on a tight budget. I can get an ATMEGA8 for like 3 bucks. And I am thinking the ATMEGA 8 cause it seems those are used alot on these USBASP's that or the ATMEGA88. I have some other MCU's at the house but not any ATMEL AVR stuff. Have a couple from ST and a couple from TI. So yeah thats why. Plus I like burning myself with my trusty soldering Iron!

If you want to make yourself a programmer yourself from a bare chip - you'll need a programmer to program it. That programmer could also program the radio directly, so makes little sense to make anything yourself in the first place...
The serial solutions like ponyprog are not so easy to use nowadays - they used to rely on a real hardware serial port on computers (usually won't work with usb-serial adapters), and needed direct access to the port which isn't possible anymore with nowaday's OS's. You can still try though if you feel like, but might just feel like a long time to spend to save the $7 or so of an usbasp or arduino nano

[jhsa]

Ok. Then google usbasp and V-USB. if you have a friends that owns an arduino you could maybe borrow it to prog the atmega

Will this work?

[jhsa]

There's a member of this forum that also sell usbasp programmers. And they work..

that one could work. It is an old model and some were shipped with a 220 ohm ( or higher ) current limiting resistor pack which caused problems. It all depends on whether the amazon seller still has old stock or just didnt update the photo of his programmer.

my programmers and support are geared toward the rc enthusiast to program their 9x,9xr,multicopter boards, and atmel based ESC.

If you have a real parallel port accessibleand and an OS that allows to use it (e.g. Win XP) you can build a simple parallel port programmer that works with PonyProg2000.

In the first time I have used it by myself to flash the radio

And I think there are diagrams available that not even use an IC, only some resistors.

I bought one from rperkins. Hey bro your right next door to me. Are you guys supposed to be getting all this snow as well. Anyway way what time of day do you usually s***?

[rperkins]

Thanks

What's even funnier is I spent 20+ years in Indianapolis. I used to work at Wavetek when it was in Beech Grove at Arlington and Churchman. I have family in New Palestine and Greenfield.

Pretty sure you meant to spell shiP Anyway I will process orders and drop them off early Monday morning ( 6 am) and they will start moving Monday afternoon. We already got 8" up in Cleveland so who knows. I know my kids and xwife are expecting school to be out on Monday if not cause of the snow, because of the temperature.

Holy smokes man. That a crazy sight for the midwest. Well stay safe out there I dont need that thing that bad to have anyone going out when they shouldnt. Just saying

[bobarry]

Now that the reason student has been given 100 ways to get a programmer, now tell him what he has to do to a stock 9x to get the programmer connected.

Hey bobarry took about 5 minutes after I sat down at the computer with programmer in hand and my TX was loading ER9X! I figured that one out with a few google searches

[bobarry]

Glad you found the simple cable addition with pictures. I'm going to do it soon on my 2nd 9x.
Flying 2 quads one with 9x & one with er9x was too confusing.
