Detailed Description
Main struct of the project and eventually defaults.
Function Documentation
◆ aaaa_to_htv()
| void aaaa_to_htv | ( | struct htv_t * | htv | ) |
convert a pre-formatted string to the struct htv.
This convert the AAAA part to htv_t->address.
- Note
- the string is stored in the struct itself.
◆ crc8_str()
| uint8_t crc8_str | ( | const char * | str | ) |
return the crc8 of the string.
- Parameters
-
str the string
◆ htv_check_cmd()
| uint8_t htv_check_cmd | ( | struct htv_t * | htv | ) |
check the validity of the x10str command string.
Based on the string lenght, choose which protocol to check. If cmd is not correct clear the cmd string and return FALSE else if cmd is ok, modify cmd and keep only AAAAPPC.
- Returns
- true: string OK, false: error
- Todo:
- should return errno code.
◆ htv_free()
| void htv_free | ( | struct htv_t * | htv | ) |
free the htv struct.
- Note
- this should be never used.
◆ s10_to_htv()
| void s10_to_htv | ( | struct htv_t * | htv | ) |
AAAAPPC:RR to htv_t.
- See also
- aaaa_to_htv
◆ s5_to_htv()
| void s5_to_htv | ( | struct htv_t * | htv | ) |
AAAAC to htv_t.
- See also
- aaaa_to_htv
◆ s7_to_htv()
| void s7_to_htv | ( | struct htv_t * | htv | ) |
AAAAPPC to htv_t.
- See also
- aaaa_to_htv.
◆ s8_to_htv()
| void s8_to_htv | ( | struct htv_t * | htv | ) |
AAAAC:RR to htv_t.
- See also
- aaaa_to_htv
Variable Documentation
◆ EE_address
| uint16_t EEMEM EE_address |
The HTV network address
◆ EE_naddress
| uint16_t EEMEM EE_naddress |
The ~EE_address to check the correct value of the address
