# # Counter devices # # When adding new entries keep the list in alphabetical order menu "Counters" config 104_QUAD_8 tristate "ACCES 104-QUAD-8 driver" depends on PC104 && X86 && ISA_BUS_API help Say yes here to build support for the ACCES 104-QUAD-8 quadrature encoder counter/interface device family (104-QUAD-8, 104-QUAD-4). Performing a write to a counter's IIO_CHAN_INFO_RAW sets the counter and also clears the counter's respective error flag. Although the counters have a 25-bit range, only the lower 24 bits may be set, either directly or via a counter's preset attribute. Interrupts are not supported by this driver. The base port addresses for the devices may be configured via the base array module parameter. config STM32_LPTIMER_CNT tristate "STM32 LP Timer encoder counter driver" depends on MFD_STM32_LPTIMER || COMPILE_TEST help Select this option to enable STM32 Low-Power Timer quadrature encoder and counter driver. To compile this driver as a module, choose M here: the module will be called stm32-lptimer-cnt. endmenu
