Acknowledgment Frames

These frames are particular data frames sent to an external device connected to the COMM
module, not allowed to be sent via PLM. They are used by the GUI interface to acknowledge
the commands sent to the module.
From the COMM interface module (SPI, USART, USB, etc.)
uint8_t *buffer;
buffer[0] = 12;
buffer[1] = APP_ACK_FRAME;
buffer[2,3] = target_module.group;
buffer[4,5,6,7] = target_module.address;
buffer[8] = (APP_ftype_t)ack_group_type;
buffer[9] = command_echo;
buffer[10,11] = CRC16;
From / to communication interface (PLM, SPI, USART, USB, etc.)
APP_userdata_t frame;
frame.source = SOURCE_PLM / ...;
frame.type = APP_ACK_FRAME;
frame.len = 2;
frame.broadcast = FALSE;
frame.group = target_module.group;
frame.address = target_module.address;
frame.data[0] = (APP_ftype_t)ack_group_type;
frame.data[1] = command_echo;
6.6.5

Programming Frames

Programming frames are used to program the PLM module parameters, as the static
address, the AESkey (if encryption is used), the data link stack working model and to clear
or read programming parameters. Normally these commands are sent locally to the module
from an external device connected to the COMM peripheral (SPI, USART, USB, etc.).
From the COMM interface module (SPI, USART, USB, etc.)
uint8_t *buffer;
buffer[0] = n + 11;
buffer[1] = APP_PROGRAMMING_FRAME;
buffer[2,3] = target_module.group;
buffer[4,5,6,7] = target_module.address;
buffer[8] = (APP_PROG_CMD_t)command;
buffer[9,..9+n-1] = programming_data[n];
buffer[9+n,9+n+1] = CRC16;
From / to communication interface (PLM, SPI, USART, USB, etc.)
APP_userdata_t frame;
frame.source = SOURCE_PLM / ...;
frame.type = APP_PROGRAMMING_FRAME;
frame.len = n + 1;
frame.broadcast = TRUE / FALSE;
frame.group = target_module.group;
frame.address = target_module.address;
frame.data[0] = (APP_PROG_CMD_t)command;
frame.data[n] = programming_data[n];
