I try to compile the sample adc.bas with axtiny816 and it is ok

Did you buy and install the add-on?[img:654270321f]https://www.mcselec.com/userpix/115_20260727_194148_1.jpg[/img:654270321f]

Hi JP,

Of course i buyed&installed.
In my pc it give errors (still win10) - but it is good idea to try on another pc.

[quote:28b5c8af7a="ok1hdu"]I don't have an Attiny816 here so I can't check it, so no guarantees, however:
The correct syntax for setting Sysclock is:[code:1:28b5c8af7a]
Config Sysclock = 16_20mhz , Prescale = 1[/code:1:28b5c8af7a]
Then it should work:[code:1:28b5c8af7a]
W = Getadc(5) : Print "W:" ; W[/code:1:28b5c8af7a]

Try use KokkeKat library. I was use it even on Mega8 https://www.mcselec.com/index2.php?option=com_forum&Itemid=59&page=viewforum&f=18

I get mine from AliExpress in China.
If you search for products using "ST7796S" or "ILI9488" on AliExpress, you will find many sellers.
It also appears that 5.0-inch TFT LCDs using the SSD1963 controller are available on AliExpress.

They are sold on eBay as well.

Hi

Thanks for sharing this clever code. It is good to see that you try these new things and share your findings and code !

O'family
Great work, thank you.
I used similar 5" screens (480 x 800 px) with SSD1963 controllers back in 2015–2017;
unfortunately, those screens and the M2560 interface have disappeared from my supplier's catalog.
Where do you get yours?
I’ve switched to Nextion HMIs; I’m happy with them, though I imagine the use case and price point are different.

Has anybody ported the open source Petite FAT File System to BASCOM? I need to read (no writing) from a microSD card using an ATtiny841. This chip is too small for AVR-DOS. But the Petite FAT should be possible on an ATtiny841. Before I try to use it with BASCOM, I wanted to find out if anybody has already gone down that road. Ideally I would like to first read the files in the root directory. Then read the selected file.

[b:7ba116c965][color=red:7ba116c965](BASCOM-AVR version : 2.0.8.7 )[/b:7ba116c965][/color:7ba116c965]

The 8-bit parallel modules are compatible with both the ILI9488 and ST7796S, allowing them to share the same library.

Equipped with level converters on all control and bus lines, the module supports operation at both 5V and 3.3V.

Designed to stack directly onto an Arduino Mega2560, this LCD module board eliminates the need for external wiring during assembly.

O-Family, huge thanks to you for all your work on this. It inspired me to make the required changes for bascom. I think users have no idea what a challenge it was/is to convert an older lib to the new word type but i have huge respect for your work. Thank you for sharing and that reminds me to hurry with the 2088. Please people : no questions about bascom 2088 here : just about the work of O-Family!
