LGT8F328P-MINI

Overview

The smallest system version made using LGT8F328P-22, compatible with arduino nano and has the same pin and size.

L1 controls LED lights for user programming

L2 is a three-in-one status indicator light for power, TX, and RX pins. [The red light is the power indicator light, the green light and the blue light are the serial port indicator lights] [If not needed, L2, R6, R7, and R8 can not be welded]

R1 and R3 are short-circuited for USB serial port reception; R2 and R4 are short-circuited for USB SW mode [If it is not used only for power supply, a dedicated downloader and dedicated serial port module are required] You can also use the tail pin for system upgrade and maintenance.

The design purpose is to reduce the cost of the USB to serial port chip and is suitable for built-in use through the USB update program.

Please tell me the basic clock problem of g2553
I want to ask what is the default frequency of MCLK SMCLK ACLK after power on? There is a tutorial in the forum that is about g2231. I wonder if it is the same? And how to select the clock source of A
Reading data using FPGA
I would like to ask all the experts: Why is it that every time I read data into the FPGA, the output is always 0?
Ask about SDQ interface
I recently used a TI battery management chip bq2023, which has an SDQ pin for communicating with the host. The information only mentioned that SDQ is a single-wire serial port, and I couldn't find its

This year's K question is, should the analysis device be connected to a 220V plug or to the socket of the monitored electrical appliance?
If you connect it directly to a 220v plug and turn on multiple electrical appliances at the same time, how can you distinguish the characteristics of voltage and current? . . .
Battery box or power bank?
