* usb_cdcacm.c: Fixups for usb_cdcacm_tx().Marti Bolivar2013-01-171-11/+8
| | | | | | | | | | | | | - 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.

* Handle sending 0 byte packets.Manuel Odendahl2013-01-172-6/+16
| | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | 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.

* | usb_cdcacm.c: reenable the endpoint if an empty bulk transfer was received.Manuel Odendahl2012-11-081-0/+7
|/ | | | | | 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>

| | | | | | | | 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>

| | | | | | | | | We'll need to mess with the linker flags to add support for ARM toolchains other than CodeSourcery's. Since the toolchain is determined in build-rules.mk, decisions that depend on it have to happen after it's included. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

| | | | | | | | 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>
* Prep usb_descriptors.h for removal.Marti Bolivar2012-08-043-63/+84
| | | | | | | | | | | | Just change names and things to fit the libmaple style. Its contents will move to the top-level <libmaple/usb.h> header next.

* Add FIXME for usb_get_ep_tx_count().Marti Bolivar2012-08-041-1/+3
| | | | | | | | | | | 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>
