Hello!

Thanks for your reply.
REG_INT_MASK is 0x3020B0, so it includes RAM_REG.
And on the scope, I can clearly see the address sent
B0 20 B0
The first B0 is in fact 30 with the write bit (0x80).

Beside this, as stated above, everything else works,
so the wr32 function works fine.

Thanks for any ...

Hello!

I'm trying to configure the screen (EVE70 with BT815) in order to get interrupts when the screen is
touched, instead of polling.
There are 8 flags for interrupts, so I have chosen bit 2 which seems to correspond to screen touch.
So the configuration I use is setting the mask to 0x00000002 ...

Hello!

Is there a way to copy the whole screen contents to somewhere in the flash, so that I can then
transfer it to an SD card for example? (I have one attached to my hardware working with STM32).

And save it either as a bitmap or as a cmpressed image?

For those who may wonder: I want to make ...

Hello!

I have already asked this on Bridgetek's forum, but it might be better to ask
actual users. And beside this, it takes ages to get my posts approved for publication.

Here is what I did:
As using bitmap (astc encoding) is a pain where you know, especially keeping track
of all the bitmaps you ...

Hello!

I was looking at EVE4x-70G-IPS, and it says 32 Mb or 128 Mb.
Is it megabits or megabytes (I suppose it's megabit, but I would like to be sure.
Next: what is the USB COMM? I mean, is it an on-board addon allowing to connect
directly with a USB port (and therefore having an out-of-box run of ...

Hello!

Another question related to the 4k limitation.
Is it possible to store to flash some instructions aimed at drawing par of a screen, and then
call the result directly from flash? I just thought that in this case it could extend the 4K limitation.
Or whatever I do I will bump into this ...

Hello!

I have a problem writing bitmaps directly into flash.
I used to write bitmaps in RAM_G first and then use the commanda to copy the RAM_G contents
to the flash using FLASHPROGRAM or FLASHUPDATE.
However, these commands require 4K byte pages, which is an average loss of 2K per bitmap for ...

Hello!

Thanks for your reply. Ok, it looks like my HTML decoder was a bad idea.


No, there is no frame buffer, let alone two, as this would require quite a lot of memory.


But I suppose there is a frame buffer somewhere anyway. The TFT has to be refreshed constantly (which
is the role of the ...

Hello Rudolph!

Thanks for your reply. So does this mean that there is no way to have more than 8k in the display
list in any case? The memory space for DL is 8K, ok, but I had the impression that any instruction
received in the DL is converted into pixels in a frame buffer, and then when swapping ...

Hello!

Right now I'm implementing a HTML text view. Well, it's overstated, let's say it's a subset of HTML allowing to change fonts and colors.
No image yet. I used replies I got in the past (thanks Rudolph!), and could implement a text justification at both side (left AND right
at the same time ...

Hello!

Thanks for your replies.


Maybe use the EVE Screen Editor and "create" the screens you want to take a screen shot of?


Yes, that's the idea. I would like to dump the buffer I'm sending by SPI / DMA on the real hardware,
then feed the emulator with it, and get the exact same screen on my ...

Hello!

I would like to know if there is some kind of emulation system for PC. Here is why:
I wrote a software for a real EVE, but now I need to write a user's manual.
I could of course take pictures (and that's what I am doing). But the problem is that
pictures are always a little bit distorted ...

Hello Raquel!



Matrix Orbital EVE3 series use the W25Q128JVSIM flash.


I have (among others) a 5 inch display which uses a W25Q32 flash (with BT815, which is EVE3, I think).
At this point, I have one question: is the BLOB different for a W25Q32 and W25Q128? I would guess it's the
same because ...

Hello!

I think this will be the last one of the series...
I got it (more or less)!
In fact, I partly replied yesterday to my own question. The rotation setup apparently
stays set until you tell the screen to unset it. That's the role of LOADIDENTITY.
Keep a variable somewhere that remembers if a ...

Hello!

I have finally managed to write bitmaps in G_RAM and use them.
But there is something unclear at the moment.
I have written 2 bitmaps as follows:
One is a right arrow (16x16), the other is a pattern sometimes found in textiles (8x8).
The arrow is written at 0, the other pattern is written at ...
