+# how to program an stm32
+
+## programming over USB
+
+### what youll need
+- USB C
+- computer with stm32CubeIDE or stm32cubeprogrammer
+
+1. plug stm32 data logger board in to the computer with a USB c cable
+2. switch the boot mode switch to `prog`
+3. press the reset button, you should hear a usb connect sound
+4. open up STM32CubeProgrammer
+5. within STM32CubeProgrammer select this drop down menu, and select usb

+
+9. next you will want to browse for the create `.elf` file that stm32cubeIDE spat out
+10. then you hit program and then your new code will be uploaded

+11. switch boot mode back to flash
+12. hit reset
+13. profit?

+
+## programming over swd
+
+### what youll need
+- 6 pin plug-o-nails
+- stlink
+- computer with stm32CubeIDE or stm32cubeprogrammer
+
+1. plug in the stlink to the computer with the 6 pin plug-o-nails connects
+2. plug in a usb c cable (this is only for power as swd techanlly shouldnt be sending power to the board)
+3. boot up either STM32cubeIDE or programmer, if you boot up programmer you can follow the same steps as USB but with swd instead
+4. if you used STM32CubeIDE, you should just be able to click the build and upload button and it will be done (i have only done this method once, i suggest looking at the stm32g4 documentaion for exact details)
