* {i2c_chip} is the I2C chip address (the first byte sent on the bus). * Each I2C chip on the bus has a unique address. On the I2C data bus, * the address is the upper seven bits and the LSB is the "read/write" * bit. Note that the {i2c_chip} address specified on the command * line is not shifted up: e.g. a typical EEPROM memory chip may have * an I2C address of 0x50, but the data put on the bus will be 0xA0 * for write and 0xA1 for read. This "non shifted" address notation * matches at least half of the data sheets :-/. * * {addr} is the address (or offset) within the chip. Small memory * chips have 8 bit addresses. Large memory chips have 16 bit * addresses. Other memory chips have 9, 10, or 11 bit addresses. * Many non-memory chips have multiple registers and {addr} is used * as the register index. Some non-memory chips have only one register * and therefore don't need any {addr} parameter. * * The default {addr} parameter is one byte (.1) which works well for * memories and registers with 8 bits of address space. * * You can specify the length of the {addr} field with the optional .0, * .1, or .2 modifier (similar to the .b, .w, .l modifier). If you are * manipulating a single register device which doesn't use an address * field, use "0.0" for the address and the ".0" length field will * suppress the address in the I2C data stream. This also works for * successive reads using the I2C auto-incrementing memory pointer. * * If you are manipulating a large memory with 2-byte addresses, use * the .2 address modifier, e.g. 210.2 addresses location 528 (decimal). * * Then there are the unfortunate memory chips that spill the most * significant 1, 2, or 3 bits of address into the chip address byte. * This effectively makes one chip (logically) look like 2, 4, or * 8 chips. This is handled (awkwardly) by #defining |
