eeprom read devaddr addr off cnt
eeprom write devaddr addr off cnt
icrc32
The icrc32 computes a CRC32 checksum.
DEFINITION:
icrc32 chip address[.0, .1, .2] count
iloop
The iloop command reads in an infinite loop on the specified address range.
DEFINITION:
iloop chip address[.0, .1, .2] [# of objects]
imd
The imd command displays I
2
C memory. For example:
imd 53 1800.2 100
displays 100 bytes from offset 0x1800 of I
2
C device 0x53 (right-shifted 7-bit address). The
.2 at the end of the offset is the length, in bytes, of the offset information sent to the
device. The serial EEPROMs all have two-byte offset lengths. The RTC has a one-byte offset
length. The temperature sensors have zero-byte offset lengths.
DEFINITION:
imd chip address[.0, .1, .2] [# of objects]
imm
The imm command modifies I
2
C memory and automatically increments the address.
DEFINITION:
imm chip address[.0, .1, .2]
imw
The imw command writes (fills) memory.
DEFINITION:
imw chip address[.0, .1, .2] value [count]
inm
The inm command modifies I
2
C memory, reads it, and keeps the address.
DEFINITION:
inm chip address[.0, .1, .2]
iprobe
The iprobe command probes to discover valid I
2
C chip addresses.
DEFINITION:
iprobe
