Hi, How to store audio files on external SPI flash (winbond 16MB)??

Not related to this problem, but maybe you got any info on getting the touch working with SquareLine Studio? Couldnt find what touch library to use and how to integrate.

Getting the touch screen (resistive one) to work on CYD 2.8" is one of the most often asking questions. It boils down to the pcb design and decisions made by the manufacturer. The two SPI buses HSPI and VSPI are used for the display and the SD card. Examples usually use the TFTeSPI library as the low level driver. This library assumes the touch controller is on the same bus as the display, only the CS pins differ. Well, not in the CYD case, the touch controller is on a completely different set of pins. To solve that i made a bit banged SPI lib which does the job: github.com/hexeguitar/CYD28_Touchscreen Not sure how you would use it in the SquareLine Studio, not using it myself, but there is an example on how to use it with LVGL. A mater of adding a driver. The linked in the description example project uses that library to handle the touch screen. Hope it helps!

can i ask a question : does this board have the Audio Amplifier already integred into that we only have to connect the speaker and no need for a seperate amplifier ?

It’s better if you breakout to a proper audio board

The volume and distortion is always a “compression” issue. Because limiters are compressors

The boards are useful for more automotive application?
