Three-terminal adjustable voltage regulator circuit based on LM317

Overview

For the circuit of the three-terminal adjustable voltage regulator based on LM317, refer to Figure 2-23 on page 22 of the Guodian competition book presented by Lichuang. After actual testing, the function is normal. When inputting 12V, the voltage output can be adjusted by rotating the potentiometer. It can only decrease but not increase. The maximum output is: input voltage -1.4V (1N4007 diode voltage drop)

MSP430 frequency is multiplied to 20M, but registers cannot be read or written during debugging, but can be written in single step. What is the reason?
Please advise as per the title
Please help me solve this problem.
The PC is a WIN64 system. I have used two unopened boards and tried CCS6.2 and CCS7.2, but the problem in the picture still occurs. When debugging in CCS, it says that it cannot link to the target boa
Slip frequency vector control based on stator flux
There are many vector control methods. Has anyone used the slip frequency control code based on stator flux linkage? Please discuss with me.
Please recommend a MIPI CSI-2 commercial receiver
RT, my graduation project is about a MIPI CSI-2 transmitter. In addition to simulation, I hope to do a physical verification. That is, I hope you can recommend a CSI-2 receiver device. It would be bes
