As the title says, I want a 100mV reference voltage for AD. I built one today using TL431, but when I looked at the output voltage with an oscilloscope, there was about 4mV of ripple. The circuit is a...
I have encountered such a situation. I can use JTAG to download to the FPGA and download to flash, but I cannot import the configuration data from flash into the FPGA after powering on.
I checked for ...
I am a beginner, and I would like to ask you a question about Flash reading and writing. In ADuc702x, Flash is uniformly addressed, and the data of Flash can be read directly using ARM instructions. C...
The communication between the MCU and the touch chip is realized through the SMBus serial communication based on C8051F. The MCU is the host and the chip is the slave. Why does the reset of the host c...
