development platform for STMicroelectronics ARM
®
Cortex
®
-M4-core-based
STM32L476ZGT6 microcontroller with three I²C buses, three SPI and six USART ports,
CAN port, SWPMI, two SAI ports, 12-bit ADC, 12-bit DAC, LCD driver, internal 128-Kbyte
SRAM and 1-Mbyte Flash memory, Quad-SPI port, touch sensing capability, USB OTG FS
port, LCD controller, flexible memory controller (FMC), JTAG debug port.
STM32L476G-EVAL, shown in Figure 1
(1)
, can be used as reference design for user
application development, although it is not considered as final application.
A full range of hardware features on the board helps users evaluate all on-board peripherals
such as USB, USART, digital microphones, ADC and DAC, dot-matrix TFT LCD, LCD glass
module, IrDA, LDR, SRAM, NOR Flash memory device, Quad-SPI Flash memory device,
