B4A开发板适配方法
# 开发板配置
这里提供一个Arduino UNO的做参考：
```json
{
"name": "Arduino UNO",
"version":"1.0.0",
"description": "Arduino UNO standard compatible board",
"compilerTool": "arduino-cli",
"core": "arduino:avr@1.8.5",
"type": "arduino:avr:uno",
"compilerParam": "compile -v -b arduino:avr:uno",
"uploadParam": "upload -v -b arduino:avr:uno -p ${serial}",
"analogPins": [
["A0","A0"],["A1","A1"],["A2","A2"],["A3","A3"],["A4","A4"],["A5","A5"]
],
"digitalPins": [
["0","0"],["1","1"],["2","2"],["3","3"],["4","4"],["5","5"],["6","6"],["7","7"],["8","8"],["9","9"],["10","10"],["11","11"],["12","12"],["13","13"],["A0","A0"],["A1","A1"],["A2","A2"],["A3","A3"],["A4","A4"],["A5","A5"]
],
"pwmPins": [
["3","3"],["5","5"],["6","6"],["9","9"],["10","10"],["11","11"]
],
"serialPort": [
["Serial","Serial"]
],
"serialSpeed": [
["1200","1200"],["9600","9600"],["14400","14400"],["19200","19200"],["38400","38400"],["57600","57600"],["115200","115200"]
],
"spi": [
["SPI","SPI"]
],
"spiPins": {
"SPI": [
["MOSI",11],["MISO",12],["SCK",13]
]
},
"spiClockDivide": [
["2 (8MHz)","SPI_CLOCK_DIV2"],["4 (4MHz)","SPI_CLOCK_DIV4"],["8 (2MHz)","SPI_CLOCK_DIV8"],["16 (1MHz)","SPI_CLOCK_DIV16"],["32 (500KHz)","SPI_CLOCK_DIV32"],["64 (250KHz)","SPI_CLOCK_DIV64"],["128 (125KHz)","SPI_CLOCK_DIV128"]
],
"i2c": [
["I2C","Wire"]
],
"i2cPins": {
"Wire": [
["SDA","A4"],["SCL","A5"]
]
},
"i2cSpeed": [
["100kHz","100000L"],["400kHz","400000L"]
],
"builtinLed": [
["BUILTIN_LED","13"]
],
"interrupt": [
["interrupt0","2"],["interrupt1","3"]
]
}
```
### 编译上传配置：
```json
"compilerTool": "arduino-cli",// 使用的编译工具，目前都是arduino-cli，不需要更改
"core": "arduino:avr@1.8.5", // 开发板核心及对应版本号
"type": "arduino:avr:uno", // 开发板类型
"compilerParam": "compile -v -b arduino:avr:uno",//编译参数
"uploadParam": "upload -v -b arduino:avr:uno -p ${serial}",//上传参数，其中${serial}是串口变量，实际使用时会替换成用户选择的串口
```
这些配置，可见(https://arduino.github.io/arduino-cli)
你可能使用到的命令：
```bash
arduino-cli core list // 列出已安装的核心
arduino-cli board search // 列出可用的开发板
```
### 引脚等配置：
```json
"digitalPins": [
["0","0"],["1","1"],["2","2"],["3","3"],["4","4"],["5","5"],["6","6"],["7","7"],["8","8"],["9","9"],["10","10"],["11","11"],["12","12"],["13","13"],["A0","A0"],["A1","A1"],["A2","A2"],["A3","A3"],["A4","A4"],["A5","A5"]
]
```
这些配置是用于block调用的，如：
