+# General Design Notes #
+
+## STM32 ##
+
+Vss is ground.
+
+### Bypass ###
+
+VDD Needs:
+- 2x 100nF
+- 1x 4.7 uF
+
+VDDA Needs:
+- 1x 10nF
+- 1x 1uF
+
+### Pin Stuff ###
+
+External interrupts can be assigned to any GPIO pin.
+
+SWDIO is PA13
+SWCLK is PA14
+
+Internal clock so OSC_IN and OSC_OUT pins can be NC.
+
+NRST is active low reset.
+
+### UART Flash Uploading ###
+
+If BOOT0 is pulled up I think it boots a bootloader that can reprogram flash through USART. Test this out on my dev board.
+
+## 74HC595 ##
+
+RCLK latches data from the shift register to the output register.
+SRCLK clocks in data from SER (and shifts all data around)
+SRCLR clears the shift register
+OE is output enable.
+
+QH' is an output pin, it clocks out the value in QH.
+
+## I2C ##
+
+STM32F030 I2C Pins:
+- PA9: I2C1_SCL
+- PA10: I2C1_SDA
