Auto Green – Sleep or power down your PC from a Bluetooth device. Since Bluetooth has a range of about 25mm it seems like it would be easier to just walk over to the PC and turn it off, rather than enabling Bluetooth, trying to get in range, pairing, loading the app…

Cloud OC – Tweak and overclock your PC from any internet connected device. What… The… Fuck… So I can remotely crash my PC?

Smart DualBIOS – The dual BIOS idea is a good one, but this utility adds a pointless feature where you can now store very small amounts of data in it. Things like passwords and contact details, in case your hard drive dies. Just in case you are tempted to actually use it there is no way to import/export this data from/to other apps, so you have to copy/paste it all manually.

Q-Share – Duplicates Windows file sharing functionality, only with a less usable interface and less compatibility. Thanks Gigabyte.

No ATA password support in the BIOS though. Sigh…

Novatech isn’t particularly cheap either.

The SPI interface only allows you to read 8 bits at a time from the FIFO, but you can pull nFFS low and then clock bits out individually without the need for a read command. The technique I use is to start reading bits that way when the RFM12B pulls its interrupt line low until I have the complete sync pattern. At that point I know I am properly aligned and can start using the SPI bus again.

The ARSSI signal is useful. To make good measurements trigger the ADC immediately after starting an SPI read command. On the ‘scope the level looks flat during receiving, but in reality I have noticed that sometimes I get the first few bytes correctly and then the stream deteriorates into noise. Still investigating that one, there are plenty of parameters to experiment with.

Unfortunately the C pre-processor is just a glorified text processor and knows almost nothing about C, so you can’t use things like sizeof(). I found this solution:

// compile time static assertions (http://www.pixelbeat.org/programming/gcc/static_assert.html)

#define ASSERT_CONCAT_(a, b) a##b

#define ASSERT_CONCAT(a, b) ASSERT_CONCAT_(a, b)

#define ct_assert(e) enum { ASSERT_CONCAT(assert_line_, __LINE__) = 1/(!!(e)) }

If you then write this:

ct_assert(sizeof(EEP_CONFIG_t) == 32);

If the condition is not true it will cause a divide by zero error on that line. Not ideal but it seems to work. In this case an EEPROM page happens to be 32 bytes and the struct is padded. Thanks to Pixelbeat.
