In 2020, we designed and built a new submarine, AUV8. With the new design we changed the microcontroller for easier maintenance and compatibilty with our new software. The AUV7 platform still had the LPC1769 microcontroller. Since we want to bring both AUVs in competition, we decided that we had to redo the whole electrical of the submarine.
Of course, to simplify and limits the programmer and software to use, we choose the compagny STM32 for our new microcontroller. The goal was to find a chip that would be low power to extend the battery life of AUV7. The idea is to keep the same functionnality so we don't have to change the software of the PC. For example, the communication procotol is gonna remain RS485. Here is the list of requirements that we use to choose the new microcontroller.
Here is a list of the microcontroller found with all the requierements listed.
