Arduino board run on Mbed-os6.8.1 (only test purpose not official). Need Mbed Studio(1.3.1) not online compiler. If you compile on the online compiler, you can get a hex file but it does NOT work!!!
Dependencies: APDS_9960 LPS22HB LSM9DS1 HTS221
1) DAPLink(LPC11U35)の準備
使用したボード →https://akizukidenshi.com/catalog/g/gK-12144/
プログラムは、nRF52840-MDK用に公開されているDAPLinkのコンパイル済のバイナリコードを使わせていただきました。
https://github.com/makerdiary/nrf52840-mdk/tree/master/firmware/daplink
LPC11U35への書込みは、SW1(ISP)を押したままSW2(RESET)を操作するとPCに「CRP DISABLD」という名称でマウントされるので、書込まれているfirmware.binを削除してから、上記のbinファイルをコピーすれば書き込みが行われます。
書込み完了後にSW1を押さずに起動すれば、「DAPLINK」として認識されます。
DETAILS.TXTでDAPLinkの内容を確認できます。
2) 接続
| Arduino Nano 33 BLE Sense | LPC11U35 Interface CPU | コメント |
| J3:Pin2 (ボード裏のパッド) | CN1:Pin3 P0_7 | SWDIO |
| J3:Pin3 (ボード裏のパッド) | CN1:Pin4 P0_8 | SWCLK |
| JP2:Pin14 GND | CN2:Pin1 GND | GND |
3)USBSerial
シリアル出力は、NANO 33 BLE SENSEボードのUSB端子経由で出力されます。
4)Mbed Studio 1.3.1を使って開発のこと！(オンラインコンパイラでは動作しません!)
5)ボードピン配置
