The output of a biological electrode fluctuates in the range of about 300mV plus or minus 100mV, and the electrode output current is very small, about 50nA. There are four proposed design schemes:1. I...
The test bench is powered by a 5V switching power supply, and many wife, Bluetooth, and zigbee experimental modules are connected. Among them, there is an ARM core board with a 7-inch LCD screen. The ...
Because I don't know how to use tft, I want to use 12864 to make an oscilloscope, but when the frequency is high, 12864 is a bit slow to respond. Is there an LCD that operates the same as 12864 but ha...
