pic voltmeter

Today I attended the PIC Seminar (that is, the seminar is actually a product recommendation meeting )! PIC brought new products this year, mainly including the following aspects: 1. WiFi module, WiFi chip. 2. Bluetooth chip and Bluetooth module. 3. Touch Screen chip and touch screen module. 4. digital models, power management, and other chips. 5. USB chip. 6. audio chip. 7. bodycom Development Board

1. 1: The binary integer 'B' or 'B' is followed by one or more binary numbers '01' enclosed in single quotes '. 2: an octal integer of 'O' or 'O' is followed by one or more Octal numbers enclosed in single quotes '123 '. 3: The decimal integer 'D' or 'D' is followed by one or more decimal numbers enclosed in single quotes '123 '. Alternatively, the decimal integer is '.' followed by one or more decimal digits '123 '. 4: The hexadecimal integer 'H' or 'H' is followed by one or more

of the PIC does not have a unique ID. Some people enable Encryption by burning the PIC read-out bus, but the device needs to be self-made.As long as it is a large number of chips sold in the market, decryption is not a headache. We can only try to use new models or uncommon models. Some people use the EEPROM in the MCU, but it is not that simple. for mass production, some skills are needed to better solve

I saw some good articles. Because the attachment is too large, I had to directly transfer it and leave an address.

Recently, a pic ultra-low power project has been done with very high power requirements. I have seen some articles on the internet before, but it is not good to test them.Here to summarize, to share a bit for the peer, software programming to pay attention to the following points,1, no module to closeThe module here is not only the enable bit, but PMD2, do not use the IO port to be placed into the outputHere and other articles on the internet say the

# Pragma idata and # pragma udata in PIC: Idata indicates the initialized data. Udata indicates that no data is initialized. When a data block does not have enough space to store a continuous data (array), # pragma idata or # pragma udata can be used to define a new region for storing data blocks. However, # pragma idata or # pragma udata application space is still limited. Generally, it cannot exceed 256. If it exceeds, it can only be done with anoth

This experiment uses a digital tube to implement the stopwatch timing function, and uses buttons to pause, continue, reset,Enable flashing of LED lights when the digital tube is suspended1. the LED light is controlled by the C port and valid at a high level.2. The bit segment of the digital tube is controlled by port A, and the data segment is controlled by port D.3. Press the key to connect to port B.Rb0 primary keyRb2 continue keyRb4 stopwatch timing start4. Service InterruptionWhen the rb0 rs
