Touch screen driver is in direct contact with the hardware part, providing taco man the most primitive device coordinate data for the upper Tslib, and can be configured sampling interval, the screen sensitivity. Sampling interval determines the number of samples per unit time, in other parameters remain unchanged, the smaller the sampling interval means more number of samples per unit of time, which means more realistic sampling, the less prone to sampling information is lost advantageous effects such as lost writing stroke input method, but because of the influence of noise, but also means that the smaller the sampling interval graphics displayed worse.
Due to the influence of various relevant period, on different hardware platforms, the relevant parameters may need to be adjusted. The relationship between these parameters are: the larger taco man the sampling interval, the fewer sampling taco man points, sampling crossover distortion, but because the information is less prone to lose strokes and other information on the case is lost, but the performance will be better taco man out of the graphics; noising algorithm sampling interval should closely interact with, the greater the sampling interval, de-noising constraints should be smaller, whereas the smaller sampling interval, de-noising constraints should be bigger. Debounce algorithm relatively independent parts, to shake more complex algorithms, the amount of computing will bring larger, system taco man load will become heavy, but good to shake algorithm can better remove jitter, during taco man the graphics rendering will get better results; sensitive indicators of the sensitivity of the touch screen and ts threshold value, generally does not require changes, refer to the reference value.
************************************** Here to talk about tslib-1.4, and 1.3 have a little bit different, the main difference is the configuration file (the master copy of this paragraph, we see just want to put this know better) Generally, tsllib-1.4 ts.conf traits of a complete configuration file as follows: module_raw input module taco man pthres module variance delta = 30 module taco man dejitter delta = 100 module linear taco man this error Couldnt load module input No raw modules loaded tsconfig: Success The first line tells tslib linux input device to read data from, need to use the input module , which is input.so file plugin directory, so you must be configured correctly TSLIB_PLUGINDIR let tslib to find module file. Other control parameters are under continuous pressure of the touch points, the variation width, and the linear trajectory calibration. Also put their corresponding needs several library files to / tslib / plugins in the second line causes taco man ". No raw modules loaded" for two reasons: Note: One of your ts.conf not specified module_raw, comes with all module_raw ts.conf have been commented out, # Uncomment if you wish to use the linux input layer event interface # module_raw input # Uncomment if you're using a Sharp Zaurus SL-5500/SL-5000d # module_raw collie # Uncomment if you're using a Sharp Zaurus SL-C700/C750/C760/C860 taco man # module_raw corgi # Uncomment if you're using a device with a UCB1200/1300/1400 TS interface # module_raw ucb1x00 # Uncomment if you're using an HP iPaq h3600 or similar # module_raw h3600 # Uncomment if you're using a Hitachi Webpad # module_raw mk712 # Uncomment if you're using an IBM Arctic II # module_raw arctic2 you should open at least a module_raw option, some people taco man chose input , to get rid of its notes module_raw input Another reason is that you are not configured correctly TSLIB_PLUGINDIR, tslib from the directory you specify is not found in module file plugin need, please check your path and file.
