| dc.description.abstract | In past microcontrollers are used for various industrial and domestic applications. an increase in the number of microcontrollers for information changing is an important subject to solve problem of low latency and multi-peripheral connected. it becomes important to maintain proper coordination among them.
When peripheral of microcontroller is not enough to use for connection of device, we provide a scheme to connect more device with low latency, flexibility, and efficiency. we use a combination of microcontrollers and one FPGA bridge for purpose of expansibility and flexibility, choosing Master-Slave architecture to build up Super-microcontroller system.
We demonstrate the platform work by making use of an UART based monitoring tool. Using the tool, we can check message from Master or Slave MCU , Get time interval between time points we need, and authenticate that the system and platform we build match research purposes .
For research purposes, we implement two kinds of PCBA to solve FPGA I/O connection to STM32H747XI FMC. these PCBs are applied with high-speed basis. We design schematic, layout PCB, make PBCA and write HDL for FPA and C for MCU.
We use Slave MCU board to get six MPU9250 by SPI controllers. Through the bridge board, the master MCU can get data from eighteen MPU9250 with three slave MCU boards. The master MCU can make more peripheral controller like this way. In master view, it has more peripheral to use for device connecting. | en_US |
