如何通过C＃和rs232（com1）端口进入i2c eeprom [英] How do I get into i2c eeprom via C# and rs232 (com1) port

问题描述

我正在尝试读取和写入芯片，这取决于i2c协议

它的传真页面计数器的e eromrom我很少尝试使用ponyprog和芯片重新设计，但我也无法想象任何解决方案



我的尝试：



c＃

i2c驱动程序

microsoft.spot.hardware;

解决方案

我会使用微控制器（ MCU ）。那是（虚拟的，通过 USB ）串行通信（ UART ） PC 和 MCU 然后 I2C MCU之间的通信和 EEPROM 。

使用 Arduino ，会非常简单（参见，实例读取和写入串行EEPROM - learn.sparkfun.com [

除了解决方案1，您还可以使用PC I2C接口。它们非常便宜并且具有USB接口，通常作为虚拟COM端口访问。这样的接口应该提供一个带有库的SDK，当使用PInvoke时也可以与C＃一起使用。



如果你只是想在不使用你的情况下读/写EEPROM自己的代码，您可以使用PonyProg，但您需要I2C接口硬件，如 PonyProg - 串行设备编程器 [ ^ ]这需要一个并行的LPT端口，该端口不再出现在最近的PC系统中。

i'm trying to read and write in chip thats depends on i2c protocol
its un eeprom for fax page counter i tryed hardly with ponyprog and chip resestter but also i can't fegure out any solution

What I have tried:

c#
i2c driver
microsoft.spot.hardware ;

解决方案

I would use a microcontroller (MCU) for that. That is (virtual, via USB) serial communication (UART) between PC and MCU and then I2C communication between MCU and EEPROM.
Using Arduino, would make that very simple (see, for instance Reading and Writing Serial EEPROMs - learn.sparkfun.com[^]).

In addition to solution 1 you can also use a PC I2C interface. These are quite cheap and have an USB interface which is usually accessed as virtual COM port. Such interfaces should provide an SDK with a library which can be also used with C# when using PInvoke.

If you just want to read / write to the EEPROM without using your own code, you can use PonyProg but you need the I2C interface hardware as described at PonyProg - Serial device programmer[^] which requires a parallel LPT port which is no longer present with recent PC systems.
