5f9ee79298 I/O Expander: Remove hard-coded PCA9555 fields from ioexpander.h definitons. Add support for an attach() method that may be used when any subset of pin interrupts occur. 
PCA9555 Driver:  Replace the signalling logic with a simple callback using the new definitons of ioexpander.h.  This repartitioning of functionality is necessary because (1) the I/O expander driver is the lower-lower part of any driver that uses GPIOs (include the GPIO driver itself) and should not be interacting directly with the much higher level application layer.  And (2) in order to be compatible with the GPIO driver (and any arbitrary upper half driver), the PCA9555 should not directly signal, but should call back into the upper half.  The upper half driver that interacts directly with the application is the appropriate place to be generating signal.

4f83d58b24 USBMSC: Fix reversed logic on waiting for SCSI thread start. 
The scsi thread was waiting for the wrong condition.

However, this was masked by the fact that the code creating the scsi thread
was also holding usbmsc_scsi_lock(priv) while initializing data, hence this
lock synchronized the scsi thread start with init completion.

9a8c3572db serial.c: Fix a race condition noted by Stefan Kolb. Between the test if the TX buffer is full and entering a critical section, bytes may be removed from the TX buffer making the wait unnecessary. The unnecessary wait is an inefficiency, but not really a problem. But with USB CDC/ACM it can be a problem because the entire TX buffer may be emptied when we lose the race. If that happens that uart_putxmitchar() can hang waiting for data to be removed from an empty TX buffer. 2016-07-22 07:47:59 -06:00

6cefbc0c3f This change provides an option to add /dev/urandom to all architectures. The pseudo-random algorithm I choose strikes an arguably-good balance between being "random" and small/fast enough for 8/16 bit MCUs. It’s the well-documented xorshift128 algorithm. It has an internal state of 128 bits that can be [re-]seeded with a write. 2016-07-17 06:42:26 -06:00

74777499bc alter the notion of 'blocksize' to be equivalent to 'flash write page size' in order to align with assumptions in the smartfs driver (at least, maybe other things do as well). 
Correct a bug that was previously masked by having blocksize=eraseblocksize which would cause buffer overflows and delicious hardfaults.
Trivial spelling changes in comments, etc.

0d41a1cd42 Before accessing the sst26 flash, the "Global Unlock" command must me executed, which I do in the sst26 driver. 
BUT. re-reading the datasheet, the WREN instruction is required to enable the execution of this command. This was not done.

I have no idea how the driver currently works except by chance. The writes
should never happen at all, the flash is half-enabled!

2cadf783fd cdcacm_unbind leaks write request objects. This arises due to freeing the 
bulk IN endpoint before the loop that frees the requests via cdcasm_freereq.
That function checks the parameters and skips the freeing if either is NULL.
Freeing the bulk IN enpoint will cause the first param to be NULL, thereby
bypassing the free operation.  To fix, I moved the release of the bulk IN
endpoint until after to loop (much as was the case for the OUT and read
requests, which did not exhibit the problem).

3d5e690977 Shadow-Mode: The output- and configuration registers of the IO-Expander 
are held in the microcontrollers memory and only written to the IO-Expander.
 This reduces bus traffic and is more error-proof than the normal read-
 modify-write operation.

 Retry Mode: If enabled and an error occurs while writing to the IO-Expander the
 current transmission is automatically repeated once.

573b1d415c * SAMV7: SPI: SPI-Freq. 40MHz; VARSELECT; hw-features 
This change adds the following improvements:
  - Increase the allowed SPI-Frequency from 20 to 40 MHz.
  - Correct and rename the "VARSELECT" option This option was included in the code as "CONFIG_SPI_VARSELECT" but nowhere  defined in a Kconfig file. The patch renames it to "CONFIG_SAMV7_SPI_VARSELECT" and corrects the implementation according the datasheet of Atmel. In short, this option switches the processor from "fixed peripheral selection" (single device) to "variable peripheral selection" (multiple devices on the bus).
  - Add a new Function to the interface to control the timing and delays of the chip according the ChipSelect lines. This function can control the delay between the assertion of the ChipSelect and the first bit, between the last bit and the de-assertion of the ChipSelect and between two ChipSelects. This is needed to tune the transfer according the specification of the connected devices.
  - Add three "hw-features" for the SAMV7, which controls the behavior of the ChipSelect:
    1. force CS inactive after transfer: this forces a (short) de-assertion of the CS after a transfer, even if more data is
      available in time
    2. force CS active after transfer: this forces the CS to stay active after a transfer, even if the chip runs out of data. Btw.: this is a prerequisit to make the LASTXFER bit working at all.
    - escape LASTXFER: this suppresses the LASTXFER bit at the end of the  next transfer. The "escape"-Flag is reset automatically.

dc1c27cee7 * This driver supports the 'I2C lcd backpack' design that is based on the PCF8574 io expander. There's a myriad of different vendors of such, but they are principally the same, save wiring and minor features like jumpers for I2C addresses. This driver supports known and unknown variants. 
*  The interface board supports HD44780-based LCD modules up to 4x32, and this driver accommodates all those formats.

2a93c66948 include/nuttx/net/netdev.h and several Ethernet drivers in arch/: Most network drivers to not support statistics. Those that do only support them when DEBUG is enabled. Each driver collects an architecture specific set of statistics and there is no mechanism in place to view those statistics. Thus, the driver feature was mostly useless. This change standardizes the driver statistics and puts the definition in the common network device structure defined in netdev.h where they can be accessed by network applications. All Ethernet drivers that collect statistics have been adapted to use these common statistics. 2015-11-26 12:08:09 -06:00
