FWIW: On the E100, I have used the Click Counter module. The cool feature in my case is that; this SPI device, if powered separately, keeps counting even when the E100 is powered off. Power up the E100, open the SPI port and the count is there. It uses the LS7366 and many modes of counting are available. 20MHz @ 3V3 40MHz @ 5V
