Yocto-PWM-Rx Ethernet

   

Combine a Yocto-PWM-Rx with a YoctoHub-Ethernet to get an autonomous appliance with built-in network connectivity:

Yocto-PWM-Rx

YoctoHub-Ethernet

The Yocto-PWM-Rx is a 2 channels PWM input. Each channel can report frequency, duty cycle, and pulse length. It works from 0.05Hz to 250Khz and accepts any -30..+30V signal as long as it crosses the 0.7V threshold.

Each channel also features a pulse counter linked to a time counter. This allows to integrate over time the output of sensors such as flow-meters. The pulse counter works from 0 to 250kHz.

The YoctoHub-Ethernet is a Fast-Ethernet module that can host three Yoctopuce modules to access them remotely. It can be powered either by a USB Micro-B cable, or directly from the Ethernet cable (PoE compatible with 802.3af standard).

Three Yoctopuce modules can be connected directly, one of which can be fixed directly on the YoctoHub-Ethernet and connected using a Board2Board-127 connector. More devices can be connected thanks to the YoctoHub-Shield extension. The YoctoHub-Ethernet can power Yoctopuce devices up to 2A.

I'd like to change the frequency Hz value to CPS (Counts per Second). I'd also like change the reported edge count to a singular event per pulse (1/2 value). How do I do this ?

Is there a way of simple doing this without digging to far into the APIs?

@cjw: The unit is hard-coded into the device and cannot be modified. The events count is done in hardware, and this hardware cannot tell the difference between up and down transitions, that's why the device reports edges count, not pulses count.

Yoctopuce, get your stuff connected.
