如何使用cy8cplc20开发外部主机应用程序

我看了应用说明AN52478的CY8CPLC10。我正在开发一个带有CY8CPLC20的项目，它的外部主机SAMD20来自Atmel。在PLCI I2C中具有低电平的功能，如PLCL I2CYSTART和PLC中的PLCI接口等高电平。
当我选择PLS20的FSK+网络+I2C选项时，有有限的功能可供我使用，例如PLC启动和PLC轮询。由于资源已经存在，我无法添加类似于您的应用程序中的一个硬件I2C块。如果我选择在PLC20中给出的I2C，我只能访问有限的函数。
你能指导我开发一下这个软件吗？我想开发应用程序，使ATMEL能够在更高的水平上控制PLC。我需要能够向PLC发送命令。IE -发送消息，读取消息更改参数等。我能通过选择PLC+Network + I2C来做这件事，或者我应该用HW块来开发它。你能就此提出建议吗？

   I looked at the application note AN52478 for the cy8cplc10. I am developing a project with cy8cplc20 with an external host samd20 from atmel.  There are functions which are available in low level  such as PLC_I2C_start in plc_i2c  and high level such as PLC_INIT in plc.c.
         

         
           
    When I choose the FSK+network+ I2C option for the plc20, there are limited functions available to me such as plc start and plc poll. I cant add a  hardware i2c block similar to the one in your application since a resource is already present. If I choose the I2C given in the plc20, I can only access limited functions.     

         
           
    Could you please guide me on the development of the software. I want to develop the application such that the atmel has control over the plc at higher level. I need to be able to send commands to the plc . i.e- send message, read message change a parameter etc. Would I be able to do this by choosing PLC+network+I2C or should I develop it using a HW block. Could you please advise on this as well.
