Software is full of bugs and glitches that make things unusable!

Hello, i have purchased the AT32 development board from your company on Aliexpress, and i got it because i saw this arduino core for it. Unfortunately the software package is littered with bugs that make the development board useless.

To start with the list of bugs, library support is very lacking, no Libraries work for this. Next it is missing some important math functions like sin() and cos(), some arduino libraries rely on these functions. Interfaces like SPI and I2C do not work at all, even though there are support libraries for them. They compile just fine, but they do not actually work. I have to control the pins myself to make the interfaces work. And lastly memory usage calculations are inaccurate and broken. The only library that seems like it would work with this platform us u8g2, but the memory calculation bloats itself a lot. How in the world do you get a memory usage of 10MB from a library that only uses less that 20KB?

The only things that seems to work in this software are Serial printing and GPIO management.

I will say my favorite feature of this software is i can modify the upload tool to program the board over UART instead of USB (i can send a picture of the configuration if anyone needs it).

At this time the development board is heavily held back by the software, and i wish it actually worked correctly. If you can take the time to read this and work on fixing the bugs i will gladly appreciate it. Thank you for your help.
