GUI Maker for Avalon Bus - FPGA SPI Bridge Panel play online

 

SCREENSHOTS

 

DESCRIPTION

Play this online game named GUI Maker for Avalon Bus - FPGA SPI Bridge Panel.

What is the purpose of this application?

You can create a GUI to operate Intel (formerly Altera) FPGA's Avalon bus in a short time. You can operate FPGA from Android without Nios II CPU.
You can place buttons, timers, graphs, etc., and describe the processing in Python.
Likewise, you can write a simple game by describing the placement and processing of 3D objects in Python.


What program should be written to ESP8266 / ESP32?

Arduino sketch　http://rapidnack.com/?p=835
Operation explanation - Display　http://rapidnack.com/?p=918
SPI Bridge Scope　http://rapidnack.com/?p=1831

Please write the above Arduino sketch to ESP.
You can use the following methods to access the Avalon bus in the FPGA.

byte[] WriteBytePacket(UInt32 addr, byte data, int timeoutInSec = 3)
byte[] WriteUInt16Packet(UInt32 addr, UInt16 data, int timeoutInSec = 3)
byte[] WriteUInt32Packet(UInt32 addr, UInt32 data, int timeoutInSec = 3)
byte[] WriteBytePacket(UInt32 addr, byte[] dataBytes, bool isIncremental = false, int timeoutInSec = 3)
byte[] WriteUInt16Packet(UInt32 addr, UInt16[] dataArray, bool isIncremental = false, int timeoutInSec = 3)
byte[] WriteUInt32Packet(UInt32 addr, UInt32[] dataArray, bool isIncremental = false, int timeoutInSec = 3)
byte ReadBytePacket(UInt32 addr, int timeoutInSec = 3)
UInt16 ReadUInt16Packet(UInt32 addr, int timeoutInSec = 3)
UInt32 ReadUInt32Packet(UInt32 addr, int timeoutInSec = 3)
byte[] ReadBytePacket(UInt16 size, UInt32 addr, bool isIncremental = false, int timeoutInSec = 3)
UInt16[] ReadUInt16Packet(UInt16 size, UInt32 addr, bool isIncremental = false, int timeoutInSec = 3)
UInt32[] ReadUInt32Packet(UInt16 size, UInt32 addr, bool isIncremental = false, int timeoutInSec = 3)


The following is a sketch for ESP32.

    client = server.available();
  } else {
    // read data from the connected client
    int n = client.available();
    if (n > 0) {
      //Serial.print("available: ");
      //Serial.println(n);
      if (n > SPI_BUF_LEN) {
        n = SPI_BUF_LEN;
      }

      // transfer data to/from SPI
      client.readBytes(spiBuf, n);
      digitalWrite(SS, LOW);
      SPI.transferBytes(spiBuf, spiReadBuf, n);
      digitalWrite(SS, HIGH);

      // return data to client
