Supercapacitor charge and discharge protection board

Overview

Use LM317 to provide a constant current charging source for the capacitor, and use a protection board to protect the capacitor from being overcharged. Suitable for 2.7V Farad capacitors. At the same time, the current is adjustable (by adjusting the resistance value of the resistor) to achieve protective charging. Compatible with 5V USB and 12VDC input, supports up to 2A

SPI Settings
Can you help me check if there is anything wrong with the settings?Why is the data 0x4141 of SPITXBUF never sent out during debugging?Test_flag4 is also 0, so I thought that no data was received, and
Applications of Optocouplers
Optocouplers are small in size, long in service life, wide in operating temperature range, strong in anti-interference performance, contactless, and completely electrically isolated from input and out
ReadFile timeout when reading HID device data
I used to be an application developer, but now I have an urgent task to communicate with a USB (HID) device. I have no idea what to do, so I just searched the Internet for a lot of information. Now I
There are harmonics at the amplifier input and output
I input 1K and 40M signals with a signal generator, and the Vpp is 1V, but the EL2070 output has harmonics of about 300M. Please tell me how to eliminate this harmonic! Thank you! The circuit connecti

The source code of the graphics library in TI Stellaris seems to be not public.
When debugging, I found that I could see the source code of some functions, but I couldn't trace some of them. Is it a library? If so, if I use a microcontroller from another manufacturer, I can no lo
