2013-01-18usb_cdcacm: Make USB lib globals weak symbols.Marti Bolivar
This allows users to override them. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
2013-01-18Merge branch 'bug/usb-full-ep'Marti Bolivar
This resolves issues related to sending full (64B) packets via USB 2.0. In this case, some hosts continue to expect more data. Add infrastructure for sending 0-byte packets to signal end of transmission, and use it in SerialUSB. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
2013-01-17usb_cdcacm.c: Fixups for usb_cdcacm_tx().Marti Bolivar
- Check if we're transmitting (instead of how many bytes are left untransmitted) before bailing, in case we're transmitting a zero-length packet. - Set transmitting=1 before setting the endpoint valid to avoid races with the USB interrupt. - Eliminate some duplicated code. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

2013-01-17Handle sending 0 byte packets.Manuel Odendahl
Added a flag to see if we are currently waiting on an interrupt to acknowledge the sending of the current IN packet. Added a method usb_cdcacm_is_transmitting() to check for that flag. Signed-off-by: Manuel Odendahl <wesen@ruinwesen.com>

Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
2012-11-08usb_cdcacm.c: reenable the endpoint if an empty bulk transfer was received.Manuel Odendahl
It is possible to receive empty bulk transfers. This would lead to the endpoint never being reenabled as this was handled by the read routine. This caused the USB to hang. Signed-off-by: Manuel Odendahl <wesen@ruinwesen.com>
2012-11-07stm32f1/rules.mk: update include path for assembler filesManuel Odendahl
stm32f1/performance: load stm32.h in order to have STM32_HIGH_DENSITY when necessary STM32_HIGH_DENSITY was not defined in isrs.S and vector_table.S for a high density STM32. This was because stm32.h where the flag is now defined (in contrast to being defined on the command line in an earlier version of libmaple) was not included. This led to crashes when using one of the high density peripherals. Updated the ASFLAGS to have the correct include path in rules.mk. Include stm32.h in the assembler files. Signed-off-by: Manuel Odendahl <wesen@ruinwesen.com>

2012-09-02"Callback versions of functions now take voidArgumentFuncPtr. We can ↵Aditya Gaddam
probably use voidFuncPtr instead, but this way people can see that the function expects something different. Existing functions haven't changed in signature. Signed-off-by: Aditya Gaddam <adityagaddam@gmail.com>"
2012-08-31"Added ability to set callbacks for interrupts that get an argument. This ↵Aditya Gaddam
argument can be the instance that needs to handle the interrupt, or just a random argument you might find useful later. Suggestions from mbolivar and iperry from pull53 on libmaple were taken into account. Signed-off-by: Aditya Gaddam <adityagaddam@gmail.com>"
2012-08-22Revert "Re-work the constraints on delay_us(). Ask GCC to allocate a register"Marti Bolivar
This reverts commit 715a63dccb3a39d7d0502fb39b900c8302a60a87. It fails to build using the 2010 CodeSourcery toolchain, which is still the latest officially supported version. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
2012-08-22Re-work the constraints on delay_us(). Ask GCC to allocate a registerMichael Hope
instead of forcing r0. Use the same operand as input and output to remove the move. Signed-off-by: Michael Hope <michael.hope@linaro.org>

2012-08-04<libmaple/usb.h>: Fix usb_descriptor_string.Marti Bolivar
uint16 is the wrong type for the bString array. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
2012-08-04Move contents of usb_descriptors.h to <libmaple/usb.h>.Marti Bolivar
These form and name of structs etc. is basically determined by the USB spec and the libmaple style guide, so there's little reason for them to change, and less reason for them to stay hidden. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
2012-08-04Prep usb_descriptors.h for removal.Marti Bolivar
Just change names and things to fit the libmaple style. Its contents will move to the top-level <libmaple/usb.h> header next. This API is still unstable, but we need to expose pieces of it in order to get the Maple-specific pieces of usb_cdcacm.c into Wirish. Adjust uses of the API appropriately.

2012-08-04usb_cdcacm: Expose line coding state.Marti Bolivar
This was already supported, so just move the line coding structure to the header and add some functions for accessing the current values. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
2012-08-04usb_cdcacm: Set endpoint to NAK before checking byte count.Marti Bolivar
Fixes an (admittedly very unlikely) race condition. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
2012-08-04Add FIXME for usb_get_ep_tx_count().Marti Bolivar
We definitely need to mask out the high bits, as RM0008 doesn't specify that they read as zero. Calling this function seems to crash the board, though. I'm not sure why, especially since usb_set_ep_tx_count(), used by usb_cdcacm.c, seems to work. Confusing. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
2012-08-04usb_cdcacm: various fixups.Marti Bolivar
Mark internal state static. Properly reset the RX/TX state on USB reset. Choose better names for countTx and newBytes. Move the exposed configuration back into the .c; this information is not beneficial to hooks. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
2012-08-03usb_cdcacm: Improve write speed.Marti Bolivar
Actually fill the TX buffer in the packet memory area, so we can send more bytes per transaction. Using the test-session benchmark, we're now clocking in the high 700KB/sec range via PySerial. With screen, rate is now about 550 KB/sec. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

2012-08-03usb_cdcacm: minor fixups.Marti Bolivar
Rename USB_Line_Coding to usb_line_coding, and rename its fields to match the spec to aid searches. Alter the line_coding global to match, fixing an incorrect comment and avoiding magic numbers. Other minor fixups and comment improvements. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
