Fix a bug as below.
- If Ether driver have been set multiple transmit data without waiting for the received data, Ether driver can not send data correctly .
Fixed SystemCoreClock calculation for LPC810 (same as for LPC812). Added MainClock variable for serial_api.
Added comments for PLL calculation. Note that SystemCoreClock for LPC810 is still 24MHz rather than rated 30MHz.
The dedicated I2C Slave byte read and byte write functions need to be called
from 'common' mbed I2CSlave API for devices that have separate Master and
Slave engines such as the lpc812 and lpc1549.
Added i2c_slave_byte_read() and i2c_slave_byte_write() for devices such as the lpc812, lpc824 and lpc1549 that have separate I2C engines for Master and Slave functions.
Added support for I2C Slave block read, block write and byte read and write. The slave address can be set and the general call address is automatically enabled. Note that the lpc812, lpc824 and lpc1549 have the same I2C engine. This new engine is very different from the lpc1768 and other NXP mbeds. The newer engine has separate controls for Master and Slave functions and they can be enable at the same time. Note that currently the lib does not support multi-master (arbitration lost is not handled).
Modifies are as below.
- Add flow control
- Change the range of baud rate that can be set in the baud function.
8138 bps more -> 128 bps more
- Fixed a bug that designation of parity had been reversed in format().
Fixed the incorrect clocksource for the baud generator. Should be MainClock instead of SystemCoreClock. This also allows the correct use of the PLL for MainClock and SystemCoreClock without breaking the serial baudrate.
LPC812 was running at 12MHz on IRC. Added and fixed PLL activation to change the clockspeed into the expected 30MHz. Clock source is still the IRC. Selecting the 12 MHz XTAL clocksource should also work with the PLL.
Added MainClock to fix wrong setting of SystemCoreClock and allow the serial_api to use the correct clock.
Quick fix of block read and write. The i2c_start is still wrong: it
should setup the address before initiating a Start condition. Status
read is also wrong in i2c_do_read.
I was getting Hard Faults in even the simplest of samples before I made
these fixes.
* WaitUs() did nothing on optimized builds. I added the volatile
qualifier to the cyc variable to make sure that the delay loop
doesn't get optimized out.
* I removed the #ifdef which skipped the fpuInit() call when building
with GCC.
If user set P0_0 as DigitalOut and set it to low, LPC1114 will be in
reset condion. To avoid this situation, p4, xp4 and dp23 was removed
from PinNames.h.
Find some bugs in USBHost common codes. Bugs as below.
- USBHostMouse.cpp
- Memory destroy will occur when the size of interrupt transfer is larger than 4 bytes.
- USBHostMSD.cpp
- Type declaration of vender dependent.
U16 -> uint16_t
- USBHostSerial.cpp
- connected() will not be "true".
- Communication with USBSerial will not start.
Please note that this commit goes with another recent commit to the nRF51822 repository which updated values under projectconfig.h. Please remember to update nRF51822 as well.
This has a bearing on issue #832.
Bugs are as below.
- Add terminal setting of IRQ4 and IRQ6 that leaked.
- When set the interrupt function by rise()/fall(), the interrupt disable state will be released by disable_irq().
- Interrupt will be continued to occur when execute disable_irq() after rise(NULL)/fall(NULL) set.
- Fix the setting timing of PMC register.
guidelines.
* Uncommented assertions in operators and added check for operator[] index < 0.
* Moved one operator from private to public, this was a typo thing.
- some minor error correction
- add pin definition for 3 tests (MBED_A5,6,7)
- add new target disco_f401vc to travis_build
travis_build and all test are OK except missing STM32F4 target
MTS_MDOT_F405RG
This is a fix for issue #285. This fix is similar to that proposed by
@oresths in the original issue.
There is code in rt_init_stack() which compares the task_id against the
value of 1 before writing MAGIC_WORD to the bottom of the stack. This
is supposed to stop the write from occurring for the main thread but
svcThreadCreate() doesn't initialize the P_TCB's task_id field until
after rt_init_stack() is executed. If any dynamic memory allocation
has occurred before the main thread is started (from the standard C
startup code) then this write could overwrite data in that allocation.
This change:
* moves the task_id initialization in svcThreadCreate() to happen
before the call to rt_init_context() is made.
* cleans up some comments in svcThreadCreate() which appear to
reference older versions of the code which would automatically
allocate stack memory if size == 0.
* still keeps the call to rt_dispatch() occurring after the call to
rt_init_context() so that the task is not dispatched to the
scheduler until the task fields have been populated.
I stepped through the rt_init_stack() code on my mbedLPC1768 after this
change was made to make sure that the write of MAGIC_WORD is now
skipped.
