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).
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.
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.
