Description
類似アプリ「FPGA SPI Bridge Panel - GUI maker for Avalon Bus」も公開しました。Avalonバスを操作するGUIを短時間で作成できます。お試しください。
Qsysのオンライン・マニュアル「Embedded Peripheral IP User Guide」の「SPI Slave/JTAG to Avalon Master Bridge Cores」に書かれているように、JTAG以外にSPIでも外部からFPGA内部を操作できます。
Arduino、Raspberry PiなどからSPI経由でFPGAに実装した回路をアクセスできるのです。Nios II CPUを組み込まなくてもいいんです。
例えば、ESP-WROOM-32をWifiーSPI変換器として使えばアンドロイド端末からWifi経由でFPGAを操作できてしまいます。こんな感じです。
アンドロイド端末 →(Wifi)→ ESP-WROOM-32 →(SPI)→ FPGA

をみていただきたいのですが、こちらにもESP-WROOM-32用のArduinoスケッチを載せておきます。

Questions & Answers
Q: What is an APK File?
A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.
Q: If I install an APK from this website, will I be able to update the app from the Play Store?
A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.
Q: Why ApkClean.net can guarantee APK 100% safe?
A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.
Q: What are Android App permissions?
A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
Don't hesitate to contact us if you have any questions or concerns.
