Thanks guys.
I figured out the touch button - pin30 reversed (low when pressed) and charging/power status. Those were the easy ones. I put my current board diff here https://github.com/fanoush/ds-d6/wiki/Espruino I an confused about the pinutils.findpin section, what it is need for? What are correct names for pins and interfaces there? Pins are not Dxx but PDxx and names like UART or USART look random across different boards.
Also how do I tell that the DFU bootloader should use negated touch button on pin 30?
I also tried to scan I2C but basically any address returns some data. I used I2C2.setup({scl:13, sda:14, bitrate:400000}) and when using I2C2.readFrom(address, 1) with random adresses it always returns something - mostly array with [232] value. What am I doing wrong? How to scan i2c for devices in espruino?
