This is a downstream E-blocks peripheral module, designed to be controlled by one of the upstream E-blocks processing boards which are available in a variety of MCU/CPLD architectures. This E-block allows the PASCO Scientific range of ScienceWorkshop Sensors to be connected to one of the E-blocks programmer boards (but not the ARM programmer). This block provides two analog input channels and two bi-directional digital channels. Each analog channel includes a selection of signal-conditioning options that can match an individual sensor output range to the input range of the microcontroller. The circuits are also protected against incorrect settings. Power supples connected to board terminals are routed to the appropriate sensor connections. A +5V supply can be obtained from the programmer board. An external ±12V supply is required for some analog sensors. E-blocks PASCO Sensor Interface Board Features - 2 analog input channels with individually selectable input ranges of -10V to +10V, 0V to +10V, or 0V to +5V
- Circuit and sensor protection against incorrect jumper settings
- 2 bi-directional digital channels
- Power supply connection and distribution
- Patch system allowing any channel to be connected to any port pin
As this board requires 5V, it is not for use with the EB185 ARM processing board. You can use it on the EB006 PIC board, the EB064 dsPIC/PIC24 board, the EB194 AVR board, the EB089 Altera FPGA board, or other 5V upstream E-blocks. E-Blocks PASCO Sensor Interface Board Resources The test routine includes a version to load into Flowcode as well as the compiled hex file. E-Blocks Overview E-blocks are small circuit boards each of which contains a block of electronics that you would typically find in an electronic system. Each E-block performs a separate function as either an input sub-system, an output sub-system, an input/output sub-system or a processing sub-system. E-blocks can be put together to form a variety of systems that can be used for teaching and learning electronics, and for the rapid prototyping of complex electronic systems. Each E-block has one or more 9-way D-type connectors that provide up to eight input/output lines and a ground line. These D-type connectors allow connection between E-blocks to be made in buses of multiples of 8 lines, just like a real electronic system. Power is routed separately to those E-blocks that need it. Processing E-blocks based on PIC, dsPIC, ARM or AVR microcontrollers control the whole E-blocks system. Processing E-blocks provide up to five input/output ports with up to eight lines per port. Please see the E-blocks Category for a list of available components. For more details on E-blocks, see the E-blocks User Guide (in English, French, German and Spanish) or watch the Introduction to E-blocks video.
