Hanshow ESL custom firmware and information

Hi there 👋

hanshowesl's Issues

What to do once the M3N@ E31HA is flashed?

Hello,

I have been playing with a donated M3N@ E31HA display and first noticed the project from @atc1441 where you mentioned your specific firmware for E31HA here: atc1441/ATC_TLSR_Paper#1 (comment)

I thus used the OTA flasher via my mobile phone to upload the zip file content, but I can't figure out what to do next.
The image has not changed on the display itself, and if I revert to the firmware sent via serial adapter, it doesn't change either, just a black rectangle that blinks around the existing content.

I must have been doing something wrong, but I'm not sure what.

RF Protocol

Hi dustybee,

Woud you mind sharing how you got the RF protocol frames structures ?
Was it by reverse engineering of the firmware or only by observation with your HackRF ?

Thanks.

A bit of offtopic request about Nebular serie

Hello guys. probably an offtopic, but I got to posses quite a lot of Nebulars 1.54" and 2.6" ones.
Anyway I am trying to avoid using the Hanshow services, and I wish to post data from my own app directly to the AccessPoint.
Do You fellows by some chance came across the way the data is packed to be sent to the AceessPoint ?

Pinout for flashing.

Hi. Can you add a pinout diagram to detail how to connect a USB/UART adaptor to the Nebular.
Thank you.

Make is not working

Hi! Awesome work here @dustybee.
The OUTPUT.zip you uploaded to an issue on the ATC_Paper repo worked for me, so now I am trying to modify your version a bit to display some custom text. Unfortunately, the make all command doesn't seem to work for me.

I get this error when trying to run it.

I get the same result when running make all btw. I haven't touched any files, the repo is still exactly how I cloned it today.

Thanks for the help!

How to create images for display

Hi, you included in project this file which contains two "images" that can be shown by the EPD by Hanshow. How did you produce those images? Thank you!

Hardware used for capturing RF protocol

Hey, I want to do a bit more investigation into the RF protocol. Can you indicate what you used to capture it?
