Dear STe2e Community, I need your help.
I'm trying to get the diplay part of Keil's MCBSTM32C dev board working. It features a STMPE811 touch screen controller. The controller is connected through I2C and everithing works more or less good exept for the values I retrieve from the controller. I suppose they come as fractals, but I couldn't find anny informations about those in the datasheet or ANs. Annyone has an idea what the x and y values format is? my best guess is 8 MSB are the significand and the 4 LSB are the exponent. Is that correct? Thanks for anny input.
