MKS TFT28 Issue with Fonts #14

Open SpankyDevil opened 3 months ago

SpankyDevil commented 3 months ago

MKS TFT28 Firmware MKS_TFT28_V3.0.27.x.bin config.ini (Only changed Serial Port 1 baudrate to 250000) TFT28 THEME_Unified Menu Material theme

When updating Fonts SD:/TFT28/font/word_unicode.fon gets to 25% and then changes to unreadable characters. Once the update is complete the Dashboard is unreadable.

  2. Created reset.txt

  3. put the SD Card into the TFT's SD Card slot

  4. start/reboot the TFT

  5. Completed Touch Calibration 20240514_184953

  6. Deleted reset.DONE 7.Placed the following files on the SD Card Firmware MKS_TFT28_V3.0.27.x.bin - renamed to MKSTFT28.bin config.ini (Only changed Serial Port 1 baudrate to 250000) TFT28 - folder from THEME_Unified Menu Material theme

Can you please post a picture of the back of your TFT board (where the MCU is)?

It seems you have a V2 TFT board which is not compatible with this firmware.

SpankyDevil commented 3 months ago

That is a real shame it seems to work really well, the only issue is the words are not in English. Would it be much effort to add support?

kisslorand commented 3 months ago

It's kind of hard to do it without having the TFT.

I recommend to buy a compatible TFT, it should be really cheap nowadays.

SpankyDevil commented 3 months ago

Fully understand. I am happy to work with you and accept any risk of bricking the device if this is an option? I feel this shouldn't need too many changes since it is working just an issue with the language or fonts.

I don't know if it makes any difference but the Original MKS TFT28_32_v3.0.6 firmware works correctly but doesn't have all the cool features of this firmware.

I am a Senior System Engineer so have lots of experience with flashing firmware, Serial connections, and some programming knowledge but not to this level required.

I find it strange that it is all in English until it gets to 25% flashing "word_unicode.fon" then it changes to something that looks like Chinese but I do not think it is Chinese.

SpankyDevil commented 3 months ago

I deleted the word_unicode.fon file from within the TFT28\Font\ Folder and created a blank file with the same name. Reflashed and now everything is working in English.

Just as I thought, memory corruption/limitation is the culprit of your issues. As you can see 193.65% SPIFlash is used. This FW's addons just doesn't fit into the memory of your TFT. You have only 4MB of SPI flash, 8MB is needed.

SpankyDevil commented 3 months ago

How is that even possible to store nearly 8MB on a 4MB. Im surprised its running so well.

I guess thats the difference between the MKS TFT28 V2.0 and V3.0 4MB vs 8MB

It's not possible.

Me too.

Could be, among other stuff.
