It doesn't, but it was still torture. I tried to convince them to waterboard me, to short 'em out, but they didn't fall for that one. Luckilly, TCE and WEX Luther were away one evening, leaving only their henchman, TCF0 guarding me. When his 24-bit timer overflowed, I was able...
This core disables the SS pin, meaning the "SS" pin can be used for whatever purpose you want, and the pin is relevant only when making an SPI slave (which requires you to implement the interaction with the SPI peripheral yourself - though it's not rocket science or anything). On the...
As soon as there is data in the circular buffer the main loop waits for 480us. After this small delay we check the amount of data in the buffer. If there's less than 4 bytes in the buffer we assume it is garbage and throw it away. This is needed because when the PC is turned ...

Then there is the silliness of open source hardware. Excuse me, but ‘source’ refers to ‘source code.’ The open hardware folks get into discussions of source that rival those on the meaning of free. So, I’m going to settle this for me by using COP — Collaborative Open Projects —...
All AVR instructions have a single 16-bit word format, meaning that every program memory address contains a single 16-bit instruction. During interrupts and subroutine calls, the return address program counter (PC) is stored on the stack. The stack is a 3 level deep hardware stack dedicated ...
Implied meaning is not afraid of difficulties rain or shine. FY means rich. I hope my customers are doing well. Money is coming in... The company's major domestic network platform strength suppliers. Its factories. Physical stores. Source factory. Source goods....
If you wonder why this matters, look at your computer’s keyboard and note the Ctrl key. It is used to alter the meaning of the rest of the keyboard in much the same way as was done by Baudot’s apparatus, which is a direct ancestor of your keyboard. Also, when we transmit somethin...

See the datasheet for details on power consumption and the meaning of these options. You must do Burn Bootloader to apply this setting, even in 2.2.0 and later; it's not a "safe" setting, since if you set it to a voltage higher that the operating voltage and enabke it, the chip ...
