Re: Additional serial ports on the 5234

Excellent, thank you! I had already downloaded the APP note but wanted to check it anyone had experience of using it. I will have my dev kit later this month so I will be keen to try it out then. I am also developing a custom board for the module anyway, so I will be adding suitable RS232 drivers as...

Re: NetBurner and the 4 - 20ma Current Loop

Another option is to simply use a high precision 100 ohm resistor (0.1%) to ground and measure the differential across this resistor with an ADC. You then get a span of 0.4V to +2V for your 4-20mA input. This is ideal for a lot of ADC's which are 0-2.5V input. I have used this method with the Microc...

I was wondering if it can support more than 1 and if anyone has actually done this in hardware and if you where successful with it? I only ne...
