Fast data transfer with C/D info #1

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
array with alternate entries
cd_info
data
cd_info
data
...
cd_info
data
cd_info

cd_info == 0
   no change
cd_info == 1
   change cd line to 0
cd_info == 2
   change cd line to 1

sequence must end in cd_info and this cd_info must be none-zero.

Introduce new message for this.

The current implementation in the msg api is this:
void ucg_com_SendCmdDataSequence(ucg_t *ucg, uint32_t cnt, const uint8_t 
*byte_ptr)
{
  ucg->com_cb(ucg, UCG_COM_MSG_SEND_CD_DATA_SEQUENCE, cnt, (uint8_t *)byte_ptr);
  ucg_com_SetCDLineStatus(ucg, 0);  // ensure that the status is set correctly for the CD line */
}

cnt is the number of cd line / data pairs
total array (byte_ptr) length is even.
