  1. I am using the SimpleWebServerWiFi example in Energia as a basis for my application, which has become a bit large. My trouble is, sometimes the update of the client web page requested is fast, while sometimes it is painfully slow without changing any code. There is only one web page. I have no idea where to start looking, is there any clues out there what can cause the web server of the cc3200 working slow? For example, if the output it is slow, hitting a button on the client web page, causes the server to fast reload the same page. regards,
  2. Hi good day ... I'm doing a project that consists of a network of RF sensors that communicate to a station connected to the Ethernet network, the target station that read the sensors and update the variables shown in the IP address configured. I have connected the module NRF24L01 SPI port 2. I am using Enrf24 library. I have the enc28j60 SPI3 module connected to the port. I am using the library UIPEthernet, configure the module to use port 3 Enc28J60Network modifying the file that is included in the same library. I have the following problem: -The NRF24L01 module works well alone. (Although this module connected and energized enc28j60). -The Enc28j60 module works well alone. (Although this module connected and energized NRF24L01). In my code, if I comment the line Ethernet.begin (mac, ip); NRF24L01 module operates but does not work enc28j60 module. If I uncommented the same line opposite happens. attached files of my project, I add my code. What could be my problem?

  3. Hi, everyone. I want to do a light web server (show temperature value and port control) with MSP430g2553 and ENC28j60 Breakout Module. At this forum, there are many examples about this issue using Energia lib. But I want to use IAR Embedded Workbench as IDE, not using Energia lib.So probably MSP430 and ENC28j60 communicate using SP?. How I do this project at IAR Embedded Workbench.Thank you
