Hello all,

I'm new to this community. I expect to acquire a M5Paper soon (once available somewhere in Canada). In the last 6 months, I have developed an EPub Reader for the InkPlate devices that are based on the ESP32. My intent is to port it to the M5Paper. I require some advice on 1) is it something that would be useful for the community and 2) Is there any issue I need to be aware of in porting the application: the availability of the screen driver is key to allow for the port to be successfull.

Thanks!

You can find the EPub reader source code here:

Hello, just to let you know that I’ve just ordered the m5paper v1.1. Will look at how I can easily port my epub reader to it.

@robski At least on paper, the Inkplate devices are very similar in capabilities to the M5Paper. No reason to not being able to port the app, but hardware stability...

@robski You can have a look at the EPub reader I wanted to port here

@robski Was ready to buy a new M5PaperS3, but with this issue, I'm becoming less and less interested. I did built some software for the Inkplate eInk/esp32 based devices (an EPub reader and other stuff). This jeopardize my effort to port them to the M5Paper-ish devices.

@robski Yes, tried several applications. Burning is fine but nothing happen on screen. As indicated, the monitoring shown that the it8951 chip responsible of managing the screen refuses to become ready. As I'm a professional embedded developer, was also able to develop some code that manage properly the battery state, the buttons and the touchscreen. But the eInk screen controller refuses to become ready.

Hello all,

I'm facing an issue I can't resolve. The M5Paper i bought sometimes ago refuse to start properly, Got that issue since I purchased the device. I've put it on the side for all that time and tried again to get it works since a week.

Tried to install the testing application and the calculator from the M5Burner app. Erased the flash memory several times before burning the apps. Nothing happen on the screen. Looking at the code and monitoring the USB port, the IT8951 refuses to become ready to be programmed. (The WaitBusy() function returns a timeout status every time it is called).

I'm desperate. Any clue on something I can do?

@ajb2k3 Thanks for your reply. Yes I did erased the flash. Any other ideas??

@ajb2k3 Thanks for the information. I was able to install it with the M5Burner, but can't get it to start. Tried to remove the usb cable, reseted the device with the back pin and turned it on with the push button on the side, nothing happened.

@ajb2k3 I'm on Linux using the M5Burner, can't see the original factory firmware. Here are the entries: UIFlow2, UIFlow, FactoryTest, Calculator, WeatherStation, ToDo, OnlineImage.
