I'm designing a electronic device running an embedded HTTP server. I'm using lwip TCP/IP stack and the httpd application that comes with lwip. Because the device is under an ADSL router and the public IP is dynamic, I need to register to a DDNS service, configure it in the router and open one port (NAT). These steps are too tricky for the most of my users. So I'm thinking to a simpler so...

I need to measure the impedance of an antenna setup and am told a Vector Network Analyser is required. For a 1-off use I am reluctant to outlay money to buy one and even the rental fee is high for such a device. Is there another way to measure impedance that will give me the same result? TIA Peter


Convert NTP UTC time to localtime (newlib)

My platform is an NXP MCU Cortex-M3 running an SNTP client on top of lwip TCP/IP stack. I correctly receive current time (seconds from epoch) in UTC. Now I would like to convert it in struct tm *localtime*. There's localtime() function that is what I tried to call. However, as expected, localtime() returns UTC. My C libraries are newlib and I suspect newlib thinks the timezone is U...

I'm using Microchip SST26VF064B SPI Flash memory with an LPC1768 from LPC. It works until I change the SPI clock frequency from 24MHz to 48MHz. I'm using HIGH-SPEED READ command that should work up to 104MHz (the power supply is 3.3V). For example I read 0x28 0x26 when they should be 0x51 0x4C. 0010 1000 0010 0110 -> 0x28 0x26 0101 0001 0100 1100 -> 0x51 0x4C They appears s
