== (100) Poll Status ==
:''See also [[Programming_the_Ethernet_controller|Programming the Ethernet Controller]]'' for a survey of modules and a general discussion of FPGA design approach.''
== (100) Query Sensor Chips ==
The Querier performs a poll of the sensor chips: Temperature Sensor and the 8-channel ADC. The returned values from these combined nine polls are stored in the [[FPGA_Registers#Temperature Register|Temperature and ADC registers]].
This block will have at least two functional blocks: one to poll the temperature sensor and one to poll the ADC. Its job is to update all status values from the status chips in preparation for transmission. Additionally, it converts all values to 16-bit two's-complement before storing locally. Once all status values have been updated it transitions to state 101.
