The platform is based on the popular Shield form factor and can plug directly into a compatible microcontroller board. 3 System Requirements The ICE Shield is intended to be programmed and controlled by microcontroller over SPI. The default firmware is also compatible with Windows based PC’s over USB. MCU Operation     4 wire SPI communication interface 3.3V VDD supply GND 2 GPIO ports (HRDY and RESET_) PC Operation   Windows® OS (XP, 7, 8 and 10) USB Type-A to Micro USB cable E Ink © 2022 Version 1.0.0 Page 1 E Ink ICE Shield 4 Hardware Description 4.1 Block Diagram Figure 2 ICE Shield Block Diagram 4.2 Pin Description Table 4-1 ICE Shield Pin Definitions STM32 Shield Pin Label 3.3V 5V D10 D9 D8 D4 D5 D7 GND D3 D12 D11 D13 D6 4.3 Pin Description 3.3V 5V IT8951 SPI CS IT8951 HRDY FLASH CS FLASH MISO FLASH MOSI FLASH SCLK GND IT8951 RESET MISO MOSI SPI CLOCK SD CS J4 Header Figure 3 J4 Header Pin Definition E Ink © 2022 Version 1.0.0 Page 2 E Ink ICE Shield 5 Evaluation MCU Firmware The ICE Shield is compatible with many microcontroller development boards that support the Shield interface. Note that some Arduino based development boards have an ICSP header for SPI that ICE Shield does not support. 5.1 Display Drivers Display software drivers are available as a reference to control the IT8951 timing controller over an SPI interface. Sample firmware for STMicroelectronics STM32L4 Discovery kit IOT node (B-L475E-IOT01) is available, please contact E Ink Sales for access. A SPI Programming Guide is available for users who want to write their own display driver. 6 Evaluation PC Software The ICE Shield can be evaluated with a PC over USB and the corresponding PC software. 6.1 Windows Mode via Windows Application ICE Shield can be evaluated as a standalone unit by using the Windows GUI software. A microcontroller board is not required if the Windows GUI software is used. Please refer to the ICE Shield User Guide for additional information. 6.2 Command Line Interface Along with the Windows GUI software, a command line interface can be used to control ICE Shield in combination with a microcontroller board. Please refer to the ICE Shield User Guide for additional information.
