LCD screen
It supports 4.3-inch TFT color LCD touch screen with 800 x 480 pixels, and drives the
LCD screen through the SMC and I2C interfaces of MCU.
LED lights
APM32F407 EVAL Board carries 3 user LED lights, which can be used for display by
users or for indication purpose during the experiment.
Keys
APM32F407 EVAL Board carries 3 user keys, which can be used for LCD menu switching
or other input purposes.
SPI Flash
APM32F407 EVAL Board carries a SPI Flash chip W25Q16, provides 16M Bit of external
storage space, and is connected to this chip through the SPI1 interface of MCU.
RS485 interface
APM32F407 EVAL Board is connected to the RS485 chip through the USART3
peripheral and provides a RS485 interface. It should be noted that the RS485 function
requires 5V power supply to work normally.
CAN interface
APM32F407 EVAL Board has an on-board CAN interface, which can be used by users for
CAN communication. It should be noted that the CAN function module requires 5V power
supply to work normally.
Ethernet interface
APM32F407 MCU is equipped with Ethernet peripheral module, which can communicate
with external physical layer chip through RMII interface. The physical layer chip on the
APM32F407 EVAL Board is LAN8720A.
DCI interface
APM32F407 EVAL Board on-board DCI interface can transmit data of OV2640 camera
through DMA and display it on LCD. It supports processing data in the formats of JPEG
and RGB565.
