members, to meet the requirements of the deletion of comments, so, SortedSet is most suitable here (time complexity O (log (N))). So, the data types I need to use are sortset and hash,sortset for paging, and hash is used to store specific key-value pairs of data, and I've drawn the following chart: In the sortset structure of the diagram above, the topicid of each topic is used as the key of the set, and the CreateDate and Commentid of the comments associated with the subject are respectively

Serial Communication Protocol _ serial communication

verify the data sent this, in the receiver we use the data received by using "mode two division" divided by the use of polynomial, if the remainder of 0 indicates that there is no error in the transmission process, if not 0 indicates that there are errors in the transmission. Step1: Confirm the use of polynomials, usually we will adopt a fixed polynomial, common several kinds of generating polynomials such as: Crc8=x8+x5+x4+x0 Crc-ccitt=x16+x12+x5+x0 Crc16=x16+x15+x2+x0 Crc12=x12+x11+x3+x2+x0 A

# Pragma idata and # pragma udata in PIC

# 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 another idea. Why cannot it be greater than 256?
