As the title says, negative polarity current signal pulse width: 10~20ns amplitude: about 20uA. To achieve I/V conversion, I plan to use OP643 operational amplifier. The circuit diagram is implemented...
[size=4] Hex 80 is sent as a sync character before each transmission. The device acknowledges with hex 90. The data frame is then sent. Each frame begins with a header byte = hex 80. The other bytes o...
I wrote an algorithm function using LM3S9B96 and downloaded it to the on-chip Flash. The execution time is 35us, which is far from the design goal. How can I put this function into RAM to run? When th...
