This commit changes the number of wait states for the stm32f103 chip to 2 instead of 4. This gets it back in line with the datasheet, but it also has the side effect of breaking I2C. Therefore, another (seemingly unrelated) change is needed: the i2cTimeout constant must be increased to a higher value to adjust to the lower flash wait states - presumably because the lower number of wait states allows the chip to run code faster.
