comment UART0 on MCBSTR9 Board STR912FAW44?
I don't understand the line UART_SendData(UART0,'AS'); The second parameter should be a single byte (u8). Not really sure what your compiler is doing with this. This line is also in a tight while loop...the second (and subsequent) time(s) through the loop, data is loaded into the UART's shift register before it has been fully shifted out (~87us @ 115200,n,8,1). Consider some type of delay in this loop.

comment Identify which face of a cube is up
I agree. A 3-axis accelerometer is the way to go. Just for reference, Atmel has some very affordable dev kit add-ons with accels, gyros, and magentometers (atmel.com/products/microcontrollers/avr/sensors_xplain.aspx). I have no affiliation with Atmel...just thought these were relatively affordable solutions relevant to the question.

comment Use UART Tx as digital output?
+1 for suggesting DTR pin instead of TX.

comment Where are static variables stored?
The placement of a const variable is controlled by a non-standard keyword sometimes. Note that there is often a way to configure the linker to define where the const variables are stored. This, of course, varies with each tool chain.

comment Is it possible to use a Microchip PIC32 as a USB host and device at the same time?
@Russell - I may be wrong but I don't think your interpreting the question quite right. I think Federico is looking for something closer to Majenko's answer. First, you can't have two host devices on the same USB bus which implies he needs a PIC32 device with two USB ports. Second, I doubt someone asking this level of question would want to bit-bang a USB interface on some GPIO pins...I think they would be looking for a PIC with two USB peripherals. Again, this is just my take on the question.

comment Which family of ARM processors should I learn: ARM7TDMI or Cortex M3?
With regards to the Cortex-M3 design being newer, I have seen some manufacturers putting their ARM7 parts on the "not recommended for new design" lists.

There are actually purpose-built circuit board washers used to clean excess flux. An example can be seen at this link

comment How can I use a build server with Keil uVision4 (MDK-ARM), script a build, use a makefile?
I think its great that your are implementing a build server. Unfortunately, I have no experience with the Keil development system so I can't really help you out. I would like to encourage you to post a solution if you when you get it worked out.
