Thanks Kilrah and MikeB

Hello,

at the moment i develop a small er9x Board for my DIY Case. Now i have a question about the orignal schematic. On PG1 ( Pin34 ) on the Atmega there is the "Check_rfpower" connected. For what do i need the Check_rfpower ? I will use frsky ( ppm, gnd and vcc only).

Kind regards
Kayle

year beer is good ... sometimes

Ok, i will have a look to get the pc0 pin working.

Kayle

You can use both, pump channel x to ppm x.

At least that's what I understand from what is in the new firmwares.

Sorry, but i don´t understand.

Does the PC0 ( free Pin on Atmega ) already change, when i switch to another protocoll ?

Kayle

Hello, i look at the schematic of the 9x and find out, that the PC0 pin is also unused. I have FrSky and Spektrum in my transmitter. At the moment i use a "hardware" switch to switch between the two RF Modules. Is it possible to get following: Model 1 select ( Protocoll PPM ) -> PC0 = 0 Mo...

No, not without modifications on the case.

I will use it in my DIY Transmitter Case and therefore it is great.

Kayle

Hi Clive,

I've posted pictures one site before. It is very easy. Just switch two jumpers on the back of the board and connect the wires directly to the level shifters on the transmitter main pcb.

Kayle

Hey everybody,

first ... i like to say thanks to Mike and sure, everyone who helps me. It works now great.

OK, in refreshDiplay()
Try changing:
lcdSendCtl(0x04);
to
lcdSendCtl(0);

I had to set lcdSendCtl(0x03).

Thanks Thanks Thanks

Kayle

Hello,

i´m kind of stupid

Please look at attachment. It shows the Com&Seg Layout. COM0 is in the Middle of the Display.

Next week i will test further.

Kayle

So, if this works it would be an option for stock lcd replacement?? The Problem is the dimensions. They are different to the stock lcd. And does it come already with backlight? Yes. Look here: http://www.ebay.de/itm/ART-New-LCD-128x64-MN-with-LED-b-l-K-W-ST7565R-3-5V-ART128064MN19-FHW-R-08-/3904084...

Hey Mike, first .... thanks for you help, it´s great :-) Today there was a big step for me. I try to set start Line at 0x40. But there was no change. Then i set the start line at 0x60 and .... it works. Look at the picture :-) The only issue now are the pixels at the left side. But i am full of hope...

Hi Mike,

i compiled the source long time ago But i think it will work today. At which point i have to add the lcdSendCtl(0x40) ( beginning or end ? ).

Kayle

Hello together, i look at the Initialization of er9x Code and the ST7565r Datasheet: lcdSendCtl(0xe2); //Initialize the internal functions lcdSendCtl(0xae); //DON = 0: display OFF lcdSendCtl(0xa1); //ADC = 1: reverse direction(SEG132->SEG1) lcdSendCtl(0xA6); //REV = 0: non-reverse display lcdSendCtl...

Thanks Mike. I could buy another LCD to look if the issue is the same. But i think it will be the same

Kayle

Hi everybody, today i flashed the er9x ( r708 ). It´s the same issue as before. Display is upside down and flipped. I read some info´s about the ST7565 and this info´s says, that it even with the same controller, there can be some alternative initialization. Now i looked in lcd.cpp and see the initi...

Hi Brent,

Thanks. I thought i can replace a st7565 lcd with another st7565 lcd. With the stock firmware i can't change the config. Tomorrow i flash er9x and will try again.

Kayle

someone forgot the attach the pulse generator.. dam it.

How to understand that ?

Kayle

Hi and thanks for reply, i swapped the data lines ( D7 from mega to D0 from the LCD ), but then there is no graphic on the LCD. I will flash er9x and will reply. @jhsa: As you can see here : http://www.artronic.pl/o_produkcie.php?id=1271 the viewing direction is 180° rotated and you are right .... i...

Hi, today i checked all connections. I can´t find the issue. Mike or SkyNorth ?? Can you see the issue ? I get the information from the seller about the Jumpers: - 80 = 8080 - 68 = 6800 ( Jumper closed ) - S = Seriell - P = Parallel ( Jumper closed ) - ER= External Resistor ( IRS ) - IR = Internal R...

Hi, i had a little success !!! :D ( with stock firmware at the moment ) After i switch the lcd to 6800 Mode an activate the IR Jumper ( disable the ER Jumper ) my lcd works. But i have a little problem now. Look at the pictures. Both halves are swapped. Can someone help me to understand this issue ?...

@Brent: IRS = high -> Is this to activate the integrated Resonator ? Because on my Board there are two Jumpers -> ER and IR. ER is connected. I assume that this pins are for External or Internal Resonator. I connected all wires like the Flysky 9x schematic and nothing works. But i wait until the sel...

Hi,

Today i switched to 6800. But there is still no graphic on my lcd

On the back of the LCD there are more "Jumpers", like ER, IR, P and S. I think P stands for Parallel and this jumper is closed. Also ER is closed. I contact the seller to get a better datasheet.

Kayle

Hey Mike,

thanks for your answer. Tomorrow i switch the resistor from 8080 to 6800.

Kayle

Hi Everybody, i´ve purchase this LCD: http://www.artronic.pl/o_produkcie.php?id=1271 . This LCD uses a ST7565R Controller, which should be the same on the stock LCD. The only difference are the onboard C´s. On the ebay LCD there are the C´s already mounted. Also the 0 Ohm Resistors for Parallel Inte...

Thats great. Thanks guys.

Edit: Atmel wrote ->

The start of an ADC conversion in Atmega64 can auto trigger on interrupt sources.
This ADC auto triggering is not implemented in Atmega128.

Does er9x use auto trigger adc on interrupts sources ?

Kayle

Hello,

just little question. I like to replace a "dead" mega64 with an mega128 ( because i have a bunch of them ). The only difference between this two mega´s is the code space .. correct ? ( ok and some fuses ).

Hi,

open your TX an measure the voltage on the Pots. You must get ~ 0-5V when you moving your Sticks.

Kayle

I know. I make my own er9x board an there is no problem with wiring. My problem is the code to drive the lcd.

Kayle

Hi Mike. Thanks for reply.

Is it lot of work to change the lcd routine ?
