raspberry pi smart board

raspberry pi smart board.?Fundamentally speaking, dealing with the signal strength gap needs to solve two problems. First, although the signal strength is extremely low, the stylus must first be detected. Second, once the stylus is detected, an accurate report must be made. These two major problems have their own difficulties. Conceptually, the most reasonable stylus detection method is to maximize the sensor signal. The problem is typically solved by minimizing the dynamic range of the sensor to signal level (very close to the expected signal level) or even by using software multiplication and filtering. However, high-gain systems are easily saturated by large inputs such as normal finger touches, so normal touches and smaller stylus signals must be handled with care. A common method is to perform two independent scans at each expected signal level to distinguish normal touches from the stylus input.
