Hi,

We have added a new test engine (called Unity) to LVGL and planning to improve the coverage. See this README about how to write and run tests.

I've already created a test for the drop-down list as an exam

• The set_mode_X() HIL functions need to support returning an error if hardware does not support that mode or if the implementation cannot put the hardware in to that mode at that time. See for an example where panic is used instead of returning an error https://github.com/tock/tock/pull/2629/files.

Hi,

This is a really esoteric issue, but I was looking through the code and found this line: https://github.com/adafruit/circuitpython/blob/e6dc3e4686c74ad1828d07475194fc45e8f65ab0/ports/atmel-samd/common-hal/analogio/AnalogOut.c#L87

However, in the datasheet here: https://ww1.microchip.com/downloads/en/DeviceDoc/SAM_D21_DA1_Family_DataSheet_DS40001882F.pdf

Section 47.6.3 does not exist (

In PROTECTED mode, the MPU is used to map regions of memory to supervisor- and/or user-accessible memory. Currently, that algorithm is very simple: The entire address range is made accessible in supervisor mode; a single MPU region is used to enable user-mode access in each user memory region.

Each MPU region must bit both of a power-of-two size and with an alignment in memory equal to the si
