Yes, but Charles was asking about how to use SAM-BA directly above, looking for the "EEPROM" tab. This is why he only got 4K, the default size is 1000 I think.

Mike.

The external EEPROM is 512K. Currently, all ersky9x data is in the first 168K. When backing up, you need to set the address to 0, and size to 2A000 minimum, but you may use 80000 as the size to get all 512K.

Mike.

You should see a TAB labelled "Serial Flash AT25" along from the default TAB "Flash". If you don't have that, then you need to update certain files to enable it.

Mike.

Useful feedback. I'm asking as I think the implementation of pot scrolling uses around 1K of flash. I'm prepared to have one or two more hex files for er9x with specific options but I don't really want to go down the compile server route. I quite like the fact that er9x is a single program without f...

Won't your motor run time be zero until you first start the motor, then be non-zero? This is exactly what my suggestion needs. Until you start the motor for the first time, CH9 is held at -100, then works as required. You can use either timer in the custom switch Tim1 or Tim2.

Will be updated to allow all the custom switches on the next revision. I will look into the NOT versions of the switches later.

Mike.

Ted: Are you using the FrSky version? That is the main one that is short on flash space.

Mike.

As er9x does not use a compilation server, it means building more versions. The #if statements are mostly in already to remove it. I was going to leave it in until the FrSky version ran out of space.

Mike.

I REALLY don't want to do that until I have to. I would definitely need to produce an updated eepe at the same time that would be able to translate between the EEPROM structures, and probably get C9X changed in the same way. It's a lot of work and time.

Mike.

When I did the recent EEPROM structure change I did allow for enhancing the number of AND switches. I just haven't had time to make use of the new facility (a byte instead of 4 bits). I wanted to be sure the EEPROM change was OK first.

Mike.

My main concern, for those new to er9x/open9x, particularly for the stock board, is when you first want to download open9x you are faced with 26 options of what you want in it, and you won't know what most of them mean, or whether you want them. So if you get er9x and learn it, you understand what m...

I'm biased as I'm currently the main developer for er9x. However, assuming you have a standard 9x with the Smartieparts board fitted, a good way to start is: Read http://openrcforums.com/wiki/index.php/Flashing_your_9x Download and install eepe. Make sure all drivers are installed, and eepe is confi...

Mutchy: Do you use the timers? Suppose you set a timer to count up, and start from zero. You could force your CH9 to be -100 by adding an extra mix line: R -100% FULL switch(!SW16) and set switch 16 to be: CS16: v>ofs Tim1 0 Switch 16 is then OFF until the timer starts counting, then it is ON. So as...

Minbari: If you set the GVAR input to ----, then you can set the value to a constant e.g. 80% in you example. I'm still working on the full implementation of GVARS, there are currently limited places where they may be used. EXPO, Dual rates and mixer weight and offset are currently implemented. In a...

How many people actually use POT SCROLLING? The three pots are available for moving left-right, up-down, and adjusting values, but are they used much? With the addition of a rotary encoder in particular, I feel they are using up valuable flash memory that could be put to better use. I am proposing t...

The physical memory is 512kb. 8kb is allocated to the general radio settings. 8kb is allocated to each model. Each of the 8kb areas is divided into two 4kb blocks. When updating either a model, or the general settings, the 'unused' 4kb block is written with the new data, then the original 'used' 4kb...

Bertrand: You say 6 chars, but the names listed have 7! Which is correct?

Mike.

Exactly, I only have 4 bits to code the extra AND switch in. If there is an unused custom switch, then that could be used to get the required option e.g.
SW1: AND |SWB !SWB
give a switch that is ON when SWB is OFF. Use that in the extra AND field.

Mike.

Eepe is for loading ER9X really. It also allows you to backup your model data and edit/simulate models on the PC. Much easier than using the radio all the time. If you want to go down the open9x route, then you need to download Companion9X (C9X). With er9x, you have a few choices of version to load,...

It not only works, it fits! Install.jpg I'll start working on the documentation package, then I'll post the gerber files, parts lists, and build info. Some real life work is getting in the way at the moment. The only thing I haven't properly tested is the serial to the M64. For that, I need to write...

Part of your problem is likely to be thay CH9, like all channels, starts at 0% (the middle), so the first few of you SWx are all ON. You could try disabling these by using the extra AND switch at the right of the custom switch screen. If you AND with a switch that powers up OFF, they will be disable...

Have you used the SAM-BA program direct, rather than through C9X?
With this you can read/write the flash memory, EEPROM memory and the co-processor to/from files on the PC. This lets you backup the EEPROM to a file.

Mike.

Do you get these problems if, on the Tx itself, you create a new model (say in slot 20) and edit the mixes/espo etc on the Tx?

Mike.

Sounds like we know why the delay occurs then. I did find a 2K7 resistor on the reset line was OK as well as the 1K. Whether you can still program the M64 with that in place I don't know. My STK500 failed almost totally by itself, so I made up a special, high current buffer (24mA) unit. This will pr...

It would seem logical to me that you repeat your own test on your own radio by swapping the tEZ. In other words, put the tEZ on your currently-non-tEZ and see what happens. Because maybe you just have one 9x that's going to delay and one that isn't? Rather than swap out all the hardware, I have dis...

That cable says it is USB to serial, and looks to have a 9-way D-type connector, so it is NOT a USBASP, and the VID and PID match those of my Prolific USB to serial device.

Mike.

Can you check your fuse settings on your system with the delay. There is a setting that defines a delay on the oscillator startup. This delay can be set to 0mS, 4mS or 64mS. Mine is set to 4mS, but if set to 64mS I reckon it would cause the delay. My fuses are set to: Extended 0xFF High 0xC1 Low 0x0...

I'll try, it will take a while though it's all soldered up to a level converter and is my main Tx I use for flying so I don't like changing it. Can you confirm you haven't removed the 47uF capacitor on the reset line of your 9X? This was recommended to people at one time as some programmers couldn't...

Yes, very confusing! I do have an error on my board, pins 1 and 5 of the programming header are swapped! I've highlighted this on my post of the circuit. I have now cut some tracks and added a couple of wires. The board now works using the 10-pin header for programming,m so I think it is all functio...

I don't have a smartieparts board, but from pictures I have seen it might have places for a 10-pin programming header. So you might be able to remove the SP board from the Tx, add the header, use it to program the bootloader into the sound board, then put everything back. Then proceed as Jhsa says. ...
