Input: param2
Unassigned 16-bit integer. Unique to each command.
Input: data
Unassigned 8-bit integer pointer. Unique to each command.
Input: length_of_data
Unassigned 8-bit integer. Unique to each command.
.read(uint8_t zone, uint16_t address, uint8_t length, boolean debug)
Reads data from the IC at a specific zone and address.
Your data response will be available at .inputBuffer .
Input: zone
Unassigned 8-bit integer.
Zone to be read from.
ZONE_CONFIG - Configuration Zone.
ZONE_OTP - One Time Programming Zone.
ZONE_DATA - Data Zone (for keys and certificates).
Input: address
Unassigned 16-bit integer.
Address within zone be read (must include modification for offset)
Input: length
Unassigned 8-bit integer.
Length of data to be read (can only be 4 bytes or 32 bytes)
Output: Boolean
True- Communication complete and message count and CRC are good.
False- Communication failure or command execution failure.
.write(uint8_t zone, uint16_t address, uint8_t *data, uint8_t length_of_data)
Writes data the IC at a specific zone and address.
Note, once a zone is locked, you can no longer write to it, and this function will return false.
Input: zone
Unassigned 8-bit integer.
Zone to be read from.
ZONE_CONFIG - Configuration Zone.
ZONE_OTP - One Time Programming Zone.
ZONE_DATA - Data Zone (for keys and certificates).
Input: address
Unassigned 16-bit integer.
Address within zone be written to (must include modification for offset)
Input: data
Unassigned 8-bit integer pointer.
Input: length_of_data
Unassigned 8-bit integer.
Length of data to be written (can only be 4 bytes or 32 bytes)
Output: Boolean
