Some API uses interface number as argument, some wants to have
rhport.
To accommodate need of rhport for functions that don't have it
rhport can be extracted from interface data.
Having just inline keyword for function specified in header
may not be enough to generate code for function.
Adding static solves this problem.
static inline is used in all other inline functions in TinyUSB.
Recommended FIFO allocation schema includes 2 maximum endpoint sizes.
Comment suggested that this is the case while it would work according
to this description only in checked endpoints were ascending sizes.
Also two same size endpoints would be counted as one.
That is fixed by way sz is filled.
Calculation used too much modulo operation while single division was enough
to account for odd FIFO sizes.
Extra space that is evenly distributed between Bulk and control endpoints
was incorrectly calculated it could prevent allocation of ISO endpoint FIFO
when bulk endpoints existed with smaller endpoint numbers.
Minimum endpoint FIFO size is 16 32bit words, FIFO space requirement is
now observed.
Operator < used in while condition was obviously incorrect.
Loop starts with checking if unsigned variable is less then 0.
This condition is always false.
This reverses condition to follow intention of of the code.
Fix a bug in writing SysEx messages.
At the start of a new USB packet (4 bytes), while in the middle of a SysEx, the code mistakenly
set the buffer length to 4, not the target length. As a consequence, the 3rd and 4th bytes from
the last packet were included, after every byte of the SysEx after the first packet of three.
The fix is simple, as it was just a typo, as can bee seen from the other branches in the same
section of if/else statements: At the start of a new packet, the code should set up the target
length... the buffer length should be left at 2 (as set on line 180).
define __USE_CMSIS instead of __USE_LPCOPEN will have startup enable FPU
on startup properly. Although it is only relevant to lpx43/40 series,
change all to __USE_CMSIS for consistency
This is helpful if you have already encoded audio data and want an
efficient way to send it. However, this approach is NOT THREADSAFE so
far and works realiably ONLY IF tud_audio_n_write_ep_in_buffer() is NOT
called form an interrupt!
b_bytes_copied was pointer with NULL value instead of
plain variable.
NULL pointer was passed to audio_tx_done_cb() and dereference
as well.
Now variable is not a pointer.
Buffer for TX and RX FIFO was not taking into account
size of element leading to out of bound access.
audio_tx_done_type_I_pcm_ff_cb() reported copied bytes was not returning
correct value number if channels was omitted in computation.
Transfer size calculation uses simpler arithmetic.
In several place p_desc_end calculation was not taking into account
that starting pointer (_audiod_itf[idxDriver].p_desc) was pointing
past interface association descriptor.
It would result in accessing random memory.
Endpoint close was implemented only in one driver so far.
This function is needed for interfaces with several alternate settings.
The way FIFO is allocated in dcd_edpt_open() allows to correctly close
only one IN endpoint (the one that was opened last).
Wrong FIFO was flushed in dcd_edpt_stall().
(epnum - 1) should only be used when accessing DIEPTXF registers.
For DIEPCTL and GRSTCTL epnum is correct index.
For ISO endpoint driver has to specify when data
is to be transmitted (odd or even frame).
Currently code was not updating this bit resulting in
data being sent every other frame.
If interval was 1ms full data packed was sent every 2ms, and
ZLP was sent in between.
If we do not yeld in ISR when we write to queue/give semaphore, the scheduler will not know of the change and will not check the queue untill the next OS tick. This change causes the task to be called immediately and makes communication many times faster.
