# Infineon Psoc6-evaluationkit-062S2 說明

## 簡介

本文檔為 `RT-Thread` 為 `PSoC6 CY8CKIT-062S2-43012`開發(fā)板提供的 BSP (板級支持包) 說明。

This is a fast display driver for interfacing ILI9341 LCD display with infineon microcontroller over an 8bit parallel (8080-II/I) bus. It's mainly written for my personal usage.

## 開發(fā)板介紹

`Psoc6-evaluationkit-062S2` 是 RT-Thread 聯(lián)合英飛凌推出的一款集成32位雙核CPU子系統(tǒng)（ ARM Cortex-M4 和 ARM Cortex-M0）的開發(fā)板，其具有單周期乘法的150-MHz Arm Cortex-M4F CPU (浮點(diǎn)和存儲(chǔ)器保護(hù)單元)，100-MHz Cortex M0+ CPU，帶單周期乘法和MPU，可以充分發(fā)揮 PSoC6 雙核芯片性能。

該開發(fā)板核心 **板載資源** 如下：

- MCU：CY8C624ABZI-S2D44，Cortex-M4主頻 150MHz，Cortex-M0主頻 100MHz，2MB Flash 和 1MB SRAM

## 外設(shè)支持

本 BSP 目前對外設(shè)的支持情況如下：

| **片上外設(shè)** | **支持情況** | **備注** |
| :----------: | :----------: | :------: |
|  USB 轉(zhuǎn)串口  |     支持     |  UART0   |
|     GPIO     |     支持     |    —     |
|     UART     |     支持     | UART0-5  |
|    Touch     |     支持     | 觸摸滑條 |

## 目前支持

- [x] Support Arduino (simple, there are a few funtions to use ardino in rtt sdk)
- [x] LCD display (8080, ILI9341)
- [ ] ...

## 快速上手

本 BSP 是以 `VS Code` 和 `RT-Thread Studio` 為開發(fā)環(huán)境，接下來介紹如何將系統(tǒng)運(yùn)行起來。

### VS Code 開發(fā)

#### 硬件連接

使用數(shù)據(jù)線連接開發(fā)板到 PC。

#### 編譯下載

## 運(yùn)行結(jié)果

下載程序成功之后，系統(tǒng)會(huì)自動(dòng)運(yùn)行。打開終端工具串口助手，選擇波特率為 115200。復(fù)位設(shè)備后，而且在終端上可以看到 `RT-Thread` 的輸出信息：

代碼

Define pinouts to connect LCD board.

uint8_t LCD_CS = A3;    // Chip Select goes to Analog 3
uint8_t LCD_CD = A2;    // Command/Data goes to Analog 2
uint8_t LCD_WR = A1;    // LCD Write goes to Analog 1
uint8_t LCD_RD = A0;    // LCD Read goes to Analog 0
uint8_t LCD_RESET = A4; // Can alternately just connect to Arduino's reset pin
uint8_t d8[] = {D8, D9, D2, D3, D4, D5, D6, D7}; // write/read the data of 8 pinouts
TFTLCD tft = TFTLCD(LCD_CS, LCD_CD, LCD_WR, LCD_RD, LCD_RESET, 240, 320, d8);

tft.begin(): initialize the lcd device.
tft.setRotation(x): set 0-3, set rotatation.
tft.fillScreen(color): set color to full background.
tft.drawPixel(x, y, color):
tft.drawLine(x,y,w,h,l,color): set position to (x,y), set width to w, set height to h, set line width to l .
tft.fillRect(x,y,w,h,color): same as drawLine usage.
tft.drawRectangle(x,y,w,h,color): same to drawLine.
tft.drawChar(x,y,char,front_color,back_color,font,is_bg): font: see application/font.
tft.drawString(x,y,string,front_color)
