下手な回路を組むより，PIC12F683を使っちまった方が楽，と考えて，久しぶりにいじってます．<\/p>\n
開発環境MPLABの最新版をダウンロードしようと，Microchip社のサイトに行ったら，mbed同様にWeb UIの開発環境がありました（MPLAB Xpress）．これを使えば，いちいちupdate\/upgradeする必要がありません．<\/p>\n
PICへの書き込みは，専用のUSB bridgeを使うことになります．これが唯一インストールが必要な部分です．<\/p>\n
しかし，一番動いて欲しいmac OS High Sierraでは，PicKit3を認識してくれません．Linuxマシン(Slackware 64)とVMWare Fusionで動くWindows 10 (64bit)では，USB bridgeをインストールすると，Web UIのボタン一つ押すだけで，問題なくPicKit 3を介してターゲットのPIC12F683に書き込んでくれます．<\/p>\n
なぜMacだけできないんだろう．ネットで探してもなかなか答えはおろかヒントにもたどり着けません．<\/p>\n
その後，別のMac miniで試したところ，USB bridgeが機能しました．同じHigh Sierraで，使っているブラウザも同じFirefoxだし，原因究明・解決は難しそうです．<\/p>\n","protected":false},"excerpt":{"rendered":"
