This completes w1-eeproom.c with the complete API. The provided test commands allow to read and write any size at any offset (the low-level code manages cross-page reads and writes. The following examples modify a pre-written eeprom, which I host in an external socket of my SPEC card: wrc# w1r 0 4 read(0x0, 4): result = 4 offset 0 (0x000): 240 (0xf0) offset 1 (0x001): 241 (0xf1) offset 2 (0x002): 242 (0xf2) offset 3 (0x003): 243 (0xf3) wrc# w1w 0 40 41 42 offset 0 (0x000): 40 (0x28) offset 1 (0x001): 41 (0x29) offset 2 (0x002): 42 (0x2a) write(0x0, 3): result = 3 wrc# w1r 0 4 read(0x0, 4): result = 4 offset 0 (0x000): 40 (0x28) offset 1 (0x001): 41 (0x29) offset 2 (0x002): 42 (0x2a) offset 3 (0x003): 243 (0xf3) wrc# w1r 30 4 read(0x1e, 4): result = 4 offset 30 (0x01e): 69 (0x45) offset 31 (0x01f): 70 (0x46) offset 32 (0x020): 71 (0x47) offset 33 (0x021): 72 (0x48) wrc# w1w 30 11 22 33 44 55 66 offset 30 (0x01e): 11 (0x0b) offset 31 (0x01f): 22 (0x16) offset 32 (0x020): 33 (0x21) offset 33 (0x021): 44 (0x2c) offset 34 (0x022): 55 (0x37) offset 35 (0x023): 66 (0x42) write(0x1e, 6): result = 6 wrc# w1r 30 6 read(0x1e, 6): result = 6 offset 30 (0x01e): 11 (0x0b) offset 31 (0x01f): 22 (0x16) offset 32 (0x020): 33 (0x21) offset 33 (0x021): 44 (0x2c) offset 34 (0x022): 55 (0x37) offset 35 (0x023): 66 (0x42) Signed-off-by: Alessandro Rubini <rubini@gnudd.com>
