not find the CC2538 I2C related sample code, in addition to a master_slave_loopback.c example loop read and write I2C, anything else gpio analog I2C, or what firmware Foundation provides the sample code, none of which is really successful to use. It seems that the number of people using CC2538 is very small, most people use CC2530 with more than 10 20 nodes to m

() Use examples: char ch; FILE *FP = fopen ("D:\\demo.txt", "r+"); ch = fgetc (FP); Represents reading a character from the D:\\demo.txt file and saving it to the variable ch. There is a position pointer inside the file to point to the current read-write location, that is, read and write to the first few bytes. When a file is opened, the pointer always points to the first byte of the file. Wi

The following small series will bring you a python generator to generate the Yang Hui triangle method (mandatory ). I think this is quite good. now I will share it with you and give you a reference. Let's take a look at the following small series to bring you a python generator to generate the Yang Hui triangle method (mandatory ).
