Real-time emulator speeds PIC16F87X development
The latest real-time emulation hardware module from RF Solutions is designed to simplifythe development of embedded systems based on Arizona Microchip's PIC16F87X family of 8-bit microcontrollers
The transmitted infra-red beam has a typical frequency of 400Hz and can be detected by the IRD1 module at a distance of up to 20m.
If the beam is broken, then both high and low output signals are generated on IRD1 pins nine and seven, respectively.
The thick-film hybrid technology used on both modules results in stable electrical characteristics and high RFI immunity.
This makes them suitable for use in harsh environments and in close proximity to other electrical devices.
Supply voltages required are 9V DC for the transmitter, and either 12 or 24V DC for the detector.
Both parts have an operating temperature range of -20 to +80C.
