Agreed, hall sensor gimbals in my 7e would be fantastic.

Judging from the fact that these switches have three wires on each of them, and the number of diodes on board, I'd assume they are 3-way switches.

Brainstorm wrote: dc59 and All: Great to hear the manufacturer of this compact multi-protocol TX has been open to feedback from the Deviation developers!

Since I still haven't had a chance to install the 4-in-1 RF module in my Devo 7e, I pre-ordered one of these Jumper T8SG, despite the potential "public beta" risk. Based on the change from "shipping Sept. 4" to "coming soon," it sounds like BG may have delayed the initial release. So I'll be following this thread closely for any updates.

On the hall sensor question, having high-quality gimbals in a compact TX like this would be incredible! I haven't seen any information whether the switches are 2- or 3-position. But it would obviously be nice to have 3-position switches, instead of end users having to replace 2-position switches first thing.

I also agree that it would be nice to see improved ergonomics, similar to the Devo 7e. The 7e's shape and rubber grips are unequaled in a compact TX. This is perfect for travel. And the kids (with small hands) can have a TX that is on par with the grown-up versions. ;)

Hi PB,

T8FG maker provide source code and I upload to mediafire (13MB), it's based on Aug. 5 nightly build.
www.mediafire.com/file/r4sdzij87duli4r/deviation-0ac6094.rar

Could you please take a look at it ?
I flashed back to their FW and now my screen is OK!

Road map of T8SG maker,

#1, improved T8SG gimbal to hall sensor and some minor changes.

#2, New model with color screen / voice support / usb charge / hall sensor gimbal .... etc.

#3, Hi-end model , all hardware design will discuss with Deviation developers,maybe will add touch screen ..... etc.

They will always listen what Deviation users need.

Edit : Their official name is Jumper and I will use this name from now.

T8FG source code has the only difference with Aug. 5 nightly build - two lines at "target\devo7e\lcd.c".

void LCD_Contrast(unsigned contrast)
{
LCD_Cmd(0x81);
int c = contrast; //contrast should range from 0 to 63
LCD_Cmd(c);
}

void LCD_Init()
{
//Initialization is mostly done in SPI Flash
//Setup CS as B.0 Data/Control = C.5
rcc_peripheral_enable_clock(&RCC_APB2ENR, RCC_APB2ENR_IOPBEN);
rcc_peripheral_enable_clock(&RCC_APB2ENR, RCC_APB2ENR_IOPCEN);
gpio_set_mode(GPIOB, GPIO_MODE_OUTPUT_50_MHZ,
GPIO_CNF_OUTPUT_PUSHPULL, GPIO0);
gpio_set_mode(GPIOC, GPIO_MODE_OUTPUT_50_MHZ,
GPIO_CNF_OUTPUT_PUSHPULL, GPIO5);
LCD_Cmd(0xE2); //Reset
volatile int i = 0x8000;
while(i) i--;
LCD_Cmd(0xAE); //Display off
LCD_Cmd(0xA6); //Normal display
LCD_Cmd(0xA4); //All Points Normal
LCD_Cmd(0xEA); //??
LCD_Cmd(0xA0); //Set SEG Direction (Normal)
LCD_Cmd(0xC8); //Set COM Direction (Reversed)
LCD_Cmd(0x2C); //Power Controller:Booster ON

I will try to build devo7e-256 with these changed lines:

Hi,
is this #1 transmitter going to be a different product, a PRO version or something, or these are going to be the changes to T8SG production unit?

It's confirmed we can't flash it out of the box with the (modified) U7E 256 build ? with the walkera flasher ?

FYI; Jumper is one of the OEM compagnies of Banggood as Eachine can be.

It is great to have a transmitter customized for Deviation. Whilst every parent got different expectations for a new born baby, all thoughts must be realistic and justified.

$99 for Jumper's existing version seems on the high side to me when I look at the price for Devo 7e and Devo 10. Recently the legendary Frsky Taranis transmitter has also hit the $170 price point. Let's see how Jumper can emerge successfully from the market.

If they did that - and provide easy access to some free ADC inputs - I may have to get off the pto on one of my long-term wishes: moving the hardware switch configuration into hardware.ini. Not just the extra stuff for the 7E/6S/U7E, but as much as possible.

Do not ask me questions via PM. Ask in the forums, where I'll answer if I can.

Thanks vlad_vy, it's working fine with your FW.
Does it really change only 2 line code as above?

#1 TX is final version of T8SG , #2 & #3 are different model and different price .............. :P
But I don't thing Banggood can sale final version of T8SG in this month because hall sensor gimbal has not been produced and tested yet.

Yes. I compared all the source files and only one file is different. Only two lines are changed in this file.

How feasible do you think it is to create hall sensor gimbals for the Devo series? The makers of the T8SG seem quite open to suggestions, and a lot of people may not be wanting to part with their Devos for this model. Surely it won't be eating into any potential sales of the new TX and also means another revenue for them while at the same time maintaining support for Deviation and also making people rethink a decision in moving over to Taranis.

If it is technically feasible could one of you developers approach them about this? Even if it's not technically achievable, how about just replacement gimbals? There is no supplier for Devo gimbals?

Once again, I will try to create separate target for T8SG.

dc59, can you test this build?

Something wrong with makefiles.

make TARGET=t8sg

BUT
...
+ Compiling 'target/devo7e/lcd.c' wrong target!!! SRC_C = $(wildcard $(SDIR)/target/$(TARGET)/*.c)
+ Compiling 'target/common/stm32/adc.c'
+ Compiling 'target/common/stm32/clock.c'
...

So I need use other approach.

dc59, can you test next attempt?
