A Step-by-Step Guide to Programming an SPI Device via USB 'spi programmer usb'

Introduction

---------

The Serial Peripheral Interface (SPI) is a popular communication protocol used in various embedded systems for connecting peripheral chips such as EEPROMs, flash memories, and other serial interface ICs. When programming these devices directly from a microcontroller can be cumbersome or time-consuming due to the limited resources available on the target board, an SPI programmer comes into play.

In this article, we will focus specifically on using a USB-based SPI programmer (Superpro IS01 or Gang ISP Programmer SuperPro IS03) for fast and efficient programming of any SPI memory device. We'll walk through each step required to successfully program your target device via the USB interface.

Hardware Requirements

----------------

- Target board with an SPI-compatible IC (e.g., EEPROM, Flash)

- USB cable

- Power source

Software Requirements

-----------------

* An integrated development environment (IDE) such as Keil uVision or IAR Embedded Workbench that supports programming of your target microcontroller.

* The relevant driver for the specific programmer board.

Step-by-Step Programming Guide

------------------------------

### 1. Connect All Necessary Cables

Firstly, ensure all necessary cables are connected correctly between your development PC and the target device:

- Remove any existing NAND or other programmers from the target board if present.

- Plug in a USB cable to connect both devices (PC and programmer) securely.

### 2. Boot Your Target Device via UART Interface

Now it's time to boot up your target microcontroller using its serial port interface (UART):

1. Connect an RS232-to-UART or similar adapter between the serial port of your PC and the corresponding UART pins on your target board.

2. Power-up your target device while holding down any necessary reset buttons until you see a boot message appear in your IDE's serial monitor window.

### 3. Program Your Target Device via SPI Interface

Now that we have successfully booted our microcontroller into programming mode, let's proceed with actually flashing the firmware onto it using the USB programmer:

1. Connect an appropriately soldered jumper wire from one of the dedicated SPI pins on your target board (usually MISO for Master-In/Slave-Out) to either pin 19 or 21 depending upon whether you're working in Slave Mode (for example, if using a Xilinx Spartan-6 LX150 FPGA).
