The ADCTSC registers are shared between the ADC Driver and the touch-screen driver. How can one register be used when processing them? -- Linux general technology-Linux programming and kernel information. The following is a detailed description. You guys give me directions
I wrote an ADC digital-to-analog conversion driver for the embedded linux test chamber, but I found that my ADC Driver and the touch-screen driver of the test chamber share the ADCTSC register. If you want the ADC digital-to-analog conversion to work properly, ADCTSC = 0. If you want the touch screen to work properly, ADCTSC = 1 will cause the ADC and the touch screen to grab the ADCTSC again, so that my ADC will not work properly. The touch-screen driver cannot be uninstalled. To uninstall the driver, you must re-port the kernel, which is very troublesome. How can you solve this problem?
