[VHDL-FPGA-Verilog] ass1_2_hamming DL : 0: Hamming codes are a class of binary linear codes. They can detect up to two simultaneous bit errors, and correct single-bit errors. In particular, a single-error-correcting and double error detecting variant commonly referred to SECDED.-a) Develop a Verilog module that will generate a 7-bit encoded data from a 4-bit data. Simulate your design for two inputs. Use even or odd parity according to the least significant figure of your ID number. b) Develop a Veriog module for generating pseudorandom 4-bit data using Linear Feedback Shift Register( LFSR) method. c) Develop a Verilog module to emulate one bit error in the data transmission. This can be done by changing only one of the encoded bits at each clock cycle. You may use a ring-counter and XOr gates for doing this. This arrangement will insert error in consecutive bits at each clock cycle. d) Design a Hamming error detection and correction circuit to restore the original data. e) Compare the original data with the restored data to verify the error correction capability of your design. If the two data sets are equal an OK signal will be set.

[VHDL-FPGA-Verilog] tlc549adc DL : 0: 利用状态机实现对TLC549的采样控制，实验时可调节电位器RW1（在开发板底板左下角），改变ADC 的模拟量输入值，数据采集读取后在数码管上显示。可以自己用万用表测一下输入电压，然后与读取到的数据比较一下。注意：数码管显示的数据不是最终结果，还需要转换。转换方法：比如，采样电压值为V ，ADC转换后读取的8位二进制数为D，Vref为参考电压值，这里是2.5V 那么以下等式成立： V=（D/256）*Vref-Using the state machine to achieve the TLC549 sampling control, adjustable experiments (in the lower left corner of the development board backplane) potentiometer RW1, change ADC Analog input value, after the data acquisition read on the digital display. You can own with a multimeter measuring about input voltage, Then compare the read data. Note: The digital display data is not the final result, but also need to be converted. Conversion method: For example, sampling the voltage value V, 8-bit binary number after the ADC read is D, Vref is the reference voltage value, here is 2.5V Then the following equation holds: V = (D/256)* Vref
