Software Description
7.4.2
The variables of this structure are:
7.4.2.1
value is set to “pending”, then there is a request from the FreeMASTER control panel to read or write the register value.
32
The variables used for the application control have the prefix “fm_”. There is one structure with the name “fm_register”.
• *fm_address - contains address of the 8-bit register
• fm_data - contains data of the 8-bit register
• *fm_address_16 - contains address of the 16-bit register
• fm_data_16 - contains data of the 16-bit register
• fm_read_write - information on the action - reading or writing to the register
• fm_status - information on the action completion
• fm_size - information on the size of the register (8-bit or 16-bit). The address and data are put in corresponding variables.
In the continuous loop, first the value of “fm_status“ is checked. It can have two enumerated values: ”pending” or “done”. If the
The value of “fm_read_write“ is then checked to see, if a write or read command is requested.
The value of the variable “fm_size” is evaluated next, to determine if the data is 8 or 16-bit size.
