I think it´s the some chip but what is my Tx line for flashing? Someone knows?

[atc1441]

Hello. That version is not supported, it has a different SOC Only TLSR version is supported

[crazy888]

Okay i messed it up................. Thanks for quick reply

[8bignic8]

I have the same display, does any one know what kind of Controller is on the Board? Or does anyone know how to falsh that badboy :D?

[8bignic8]

i found this: https://github.com/CursedHardware/hanshow and my serial number on the Board leeds me to this: https://github.com/CursedHardware/hanshow/blob/master/HS_EL5102.md

[atc1441]

The chip on it is an MSP430 It is an 8051 core SOC and does only support propriatary RF protocolls, no Bluetooth, just as info

[8bignic8]

But could still hook it up to esp8266 and write to it?

[atc1441]

Yes that is possible

[crazy888]

Yes that is possible

The question is how :) ?! Soldering the pins is impossible. The SOC is so small and i dont know even where and how to connect the ESP.

[8bignic8]

theoretically you got vcc 3,3v gnd Ground, DA data?, ck clock? , cs chip select, nrst reset?

But it´s controlled by the chip on board already? So you have to desolder the existing SOC?

[8bignic8]

no you can use the i2c or uart bus on the other side. from your first picture at the top of the issue

[8bignic8]

theoretically you got

• vcc 3,3v
• gnd Ground,
• DA data?, -
• ck clock? ,
• cs chip select,
• nrst reset?

You need to create a custom firmware that you flash on the MSP430 or you need to desolder it and solder to the screen pins.

But both options are not part of this repo i am afraid.

Here is an example of soldering to the display pins: https://youtu.be/RUoMztFxUpE

Have a look @ https://cursedhardware.github.io/epd-driver-ic/SSD1675B.pdf in section 6.1.2

The 4-wire SPI consists of serial clock SCL, serial data SDA, D/C# and CS#. The control pins status in 4-wire SPI in writing command/data is shown in Table 6-2 and the write procedure 4-wire SPI is shown in Table 6-2

Or warong Datasheet: rigth one: https://www.texim-europe.com/getfile.aspx?id=108182

if found the Datasheet for the antenna: https://datasheet.lcsc.com/szlcsc/2001071135_AMICCOM-Elec-A71X06AQFI-Q_C479510.pdf

maybe we could build upon that :)
