bcd_len is the number of BCD digits, usually 10 or 8 in 1-Hz units, and 6 digits in 100-Hz units for Tx offset data.
Hope the compiler will do a good job optimizing it (esp. w/the 64bit freq)
Returns a pointer to (unsigned char *)bcd_data.
unsigned char* to_bcd_be | ( | unsigned char | bcd_data[], |
unsigned long long | freq, | ||
unsigned | bcd_len | ||
) |
Convert from binary to 4-bit BCD digits, big-endian.
bcd_data | |
freq | |
bcd_len |
Same as to_bcd, but in big-endian order (e.g. byte order 12 34 56 78 90 for 1234567890 Hz)
int write_block | ( | hamlib_port_t * | p, |
const char * | txbuffer, | ||
size_t | count | ||
) |
Write a block of characters to an fd.
p | rig port descriptor |
txbuffer | command sequence to be sent |
count | number of bytes to send |
Write a block of count characters to port file descriptor, with a pause between each character if write_delay is > 0
The write_delay is for Yaesu type rigs..require 5 character sequence to be sent with 50-200msec between each char.
Also, post_write_delay is for some Yaesu rigs (eg: FT747) that get confused with sequential fast writes between cmd sequences.
input:
fd - file descriptor to write to txbuffer - pointer to a command sequence array count - count of byte to send from the txbuffer write_delay - write delay in ms between 2 chars post_write_delay - minimum delay between two writes post_write_date - timeval of last write
Actually, this function has nothing specific to serial comm, it could work very well also with any file handle, like a socket.
