Re: EXC3188-FG31 Touch Controller Eegalaxy
Hello,
thanks for reply.
But this User manual is for directly connect the controller board to the PC via usb?? right ?? afterwardsu can calibrate it by that sofwarte in user manual ??right ?. But on the devices i dont have a windows installed, it works by andorid and the parameters are saved in the IC as eeti told me.
is there no method to read the chip and flash/copy it ?

Re: EXC3188-FG31 Touch Controller Eegalaxy
[B]Hello,
i have some updates in this case: [/B]
I got a mail from the service of eeti and they told me :
EXC3188 is a PCAP (Projective Capacitive) touch control IC, it can only works properly with corresponding firmware.
For different project, it needs individual firmware, not be able to mix between projects, also there is NO common firmware for PCAP touch IC.
So, unless you have the original corresponding firmware with the device you are trying to fix, or it will not work correctly...Leave a comment:

Re: EXC3188-FG31 Touch Controller Eegalaxy
Hello,
thanks for reply.
the flux issue can be right, i will check this tommorow
Its a 18,5" Screen (widescreen) mounted to the controller.
I had some cases with the old version of that controller type EX5440-CG11
(not balled IC,same devices) but by this type also it was not need to recalibrate the touch.
Note: i orderd the EXC3188-FG31 by same supplier were i also bought the EX5440-CG11 and they was perfectly working.

EXC3188-FG31 Touch Controller Eegalaxy
Hello,
i have a question. I have a fault by a device were the touch controller is faulty.
So i orderd the Controller EXC3188-FG31 and mounted it on the PCB and the device is starting (without the contoller it does not start) but the positioning of the fingerprint is not correct on some points i have the correct position but und the downside of the touch i get no reaction.
i think the contoller is well mounted on pcb and dont have any contac error, but i had the same issue on 2 devices.
Note : there is no possibility to make a touch... -
Re: I2C Programming - How to ?
Hello,
thanks for your support.
Maybee i have to tell the whole story about it
i have 5 pcb`s from that device wich are not starting.
(Industrial device, same like a notebook with touch panel)

Normally the starting sequence on power supply:[/U][/B]
beginn 0,3Amp raise up to 0,55Amp and then the devie Start by 1,4Amp
[B][U]by this 5 pcbs i had some different starting sequencenes and the pcbs are not starting. [/U][/B]

I2C Programming - How to ?
Hello,
can someone tell me more about i2c programming wich interface & software is used for.
And the most important question is:
Is it possible to read the i2c data from a device, to copy it to another device.
The part wich i need programm is a TPS658621C
[url]https://pdf1.alldatasheet.net/datasheet-pdf/view/317427/TI/TPS658621A.html[/url]
here the dataheet, i already found the pins H4 and J2 for SDA & SCL for the connection ,but i dont know wich software and programmer is the right one.

Re: TPS65862IC Programmer & socket?
Hello, thank you for your reply.
No its a industrial device with a pcb like a notebook.
The problem is there are no schematics for this board available.
I see that the TP658621C is faulty, and i have to change it.
I also have a defective board where i can track / trace the line to the progamming pins. But i cant find the correct datasheet for the TP658621C to find out the pinout.
In this datasheet for TP658621C there is a pinout but the imaged bga has
11 X 11 contacs(legs)...Last edited by Richi_el; 11-21-2021, 11:23 AM.Leave a comment:

Re: Question for MMC experts
Hello thnx for reply , i should update the case.....
ive seen there is a difference between that 2 Mmc, one is 8 the other 64GB
I have now another problem, when i desolder the JY995 (8GB MMC) and try to backup it with the RT809H programmer the software and partitions on the JY995 are destroyed and i cant make a backup(see pic 1).....
Normally the software is linux based and there should be some partitions like on (pic 2)
Can somebody tell me another option without killing the mmc...Leave a comment:

Question for MMC experts
do somebody know the difference between this Micron MMC ??
MTFC8GAKAJCN-4M IT (JY997) and MTFC8GLDEA-1M WT (JWA07)
both are
FLASH - NAND IC 64 Gb (8 G x 8) MMC 153-VFBGA (11,5x13)
there shouldnt be a difference same pinout ,same size, .... am i right?
is it necassary to take exactly the same mmc when u have to change the mmc couse of a fault ? -
