The functions descriptions are the same as for static mode. You can even assign your implemented static mode functions to the dynamic mode function pointers.
Control functions
The following functions are used to initialize the FT245 driver and control it.
void FT245_init(ft245_t *ft245)
Initializes the ft245_t instance.
Initializes the RX/TX buffers and sets all I/O signals to input.
Parameters:
ft245:ft245_tinstance.
void FT245_periodic(ft245_t *ft245)
Runs the internal communication logic and iterates the state machine. Automatically toggles the CLK signal and responds to input signals. Needs to be called periodically via timer interrupt or in a loop for this driver to work properly.
Parameters:
ft245:ft245_tinstance.
Runtime functions
The following functions are used to send/receive data in runtime after initialization.
bool FT245_write_buffered(ft245_t *ft245, uint8_t *data, size_t size)
Writes a given amount of data, specified with size, to the output buffer. It will be sent automatically on one of the following FT245_periodic(...) calls.
Parameters:
ft245:ft245_tinstance.data: Pointer to the data buffer to be sent.size: Amount of data elements to send.
Returns:
true: Data successfully transferred to output buffer.false: Data could not be transferred to output buffer.
size_t FT245_read_buffered(ft245_t *ft245, uint8_t *data, size_t size)
Reads up to the given amount of data from the input buffer, specified with size, to the pointer data.
Parameters:
ft245:ft245_tinstance.data: Pointer to the data buffer to be read.size: Amount of data elements to read.
Returns:
- Number of bytes actually read.
bool FT245_write_word_buffered(ft245_t *ft245, uint32_t word)
Writes a full 32-bit word word to the output buffer. It will be sent automatically on one of the following FT245_periodic(...) calls.
Parameters:
ft245:ft245_tinstance.word: 32-bit data word to be sent.
Returns:
true: Data word successfully transferred to output buffer.false: Data word could not be transferred to output buffer.
bool FT245_read_word_buffered(ft245_t *ft245, uint32_t *word)
Reads one data word from the input buffer, if available, to the location pointed to by word.
Parameters:
ft245:ft245_tinstance.word: Pointer to the location the word gets transferred to.
Returns:
true: Data successfully transferred toword.false: Data could not be transferred toword, i.e. no full word available at input buffer.
size_t FT245_available_read(ft245_t *ft245)
Returns the number of bytes available in the input buffer.
Parameters:
ft245:ft245_tinstance.
Returns:
- Number of bytes available in the input buffer.
size_t FT245_available_write(ft245_t *ft245)
Returns the available space (in bytes) of the output buffer.
Parameters:
ft245:ft245_tinstance.
Returns:
- Available space (in bytes) of the output buffer.
