Re: Audio (voice) - Stock 9X PCB

Actually, the QX7 has a place on the board for a larger EEPROM/Flash device. The layout matches the device used on the SKY/AR9X/9Xtreme boards, so the 32K EEPROM can be sorted for scratch builds, or quite possibly to use the QX7 board as a mod board for a 9X. The layout shows a 32Mbyte device, we us...

Re: Audio (voice) - Stock 9X PCB

Just to be clear, the 2561 and the 2560 are the same chip in different packages, the 2561 is in a 64-pin package and the 2560 is in a 100-pin package. I also agree there is no reason to use an AVR chip in a new board, the ARM processors are MUCH more capable. With the FrSky QX7 available at a very r...

Re: ERSKY9X Coding

I agree that other things like the weight of a mix don't need any improved resolution. If absolutely needed, there are ways of achieving this, e.g. by having a mix set to a weight of about 200, then a second mix with a weight of 50% and a multiply multiplex. The first mix then provides a resolution ...

Re: tunergy 9x eeprom error! help

Please try flashing er9x again using eepe. After the attempt, go to the "Burn" menu in eepe, and select "Review Output", you should get a window up showing what AvrDude did. Copy the text and post it here so we can see what took place.

Re: Maintenance mode

I wrote the bootloader originally for the Atmel processor. This provides a routine in ROM to allow writing to the flash memory. When I ported the bootloader to the STM processor, I decided to run it from RAM so it wasn't trying to read from flash memory while also writing to it. There was never any ...

Re: Ersky9x Bug Reporting

This one is just for you to test the EEPROM chip. If it solves your problem, then I'll see if I can find a way of selecting the required 'half' of the chip.
No, I don't think flashing the er9x file can cause the error, and flashing the blank EEPROM file should clear everything.

Re: Ersky9x Bug Reporting

My current thought is a block of the EEPROM is failing to write properly. On the 9Xtreme, the EEPROM chip is actually double the capacity required. So, I've posted a special test version of ersky9x that uses the second half of the chip. Note that the bootloader won't "know" about this, so accesses f...

Please use the option in eepskye under the "Burn" menu of "Write EEPROM Memory from File", and select this file to write. When you power up the radio, it should then say "Bad EEPROM", and then "...

The QX7 includes 2, 2-pin sockets ready for the addition of two extra switches. With ersky9x, you have the "BASIC" scripting available. Regarding extra pots/sliders, the QX7 has a three colour LED in the power switch (red, blue and green). I'm not sure this is very useful, indeed, on ersky9x, I only...

I've considered before whether using a second processor could help with the 9X, but I've never found a way to split the functions between two processors to reduce the flash/RAM requirements on the AVR processor.

No it doesn't have a DAC. It does, however, have timers that may run at up to 72MHz. These are able to provide PWM output (driven by DMA), so better audio with fewer filter components needed. I'm not sure whether any work could be offloaded from the main processor. To add another RF module output it...

Re: Audio (voice) - Stock 9X PCB

Most of the pins of the STM ARM processors are 5V tolerant, so you shouldn't need a voltage divider on the RX pin, and a 3.3V FTDI is only likely needed if the supply from it is used directly on the processor.

Unfortunately, the hardware design of the 9X means the trainer port cannot be used for serial data. Two reasons: 1. The protocol signal to the Tx module is driven by software. This means the timing has to be kept very accurate, particularly when using the Multiprotocol module which is serial data at...

Re: Adding MAVLINK support

There is an er9x build that should support MAVLink directly (er9x-ardupilot.hex), but only MAVLink, not FrSky.
I've never really looked at that code, I just continue to build a release version.
