notice: msp430-gdbproxy: waiting on tcp port
I have a new MSP430F169, when I run msp430-gdbproxy I received message:

pt1000 rtd schematic
Thank You for suggestions!
Ok, I will test Pt1000 with 1mA current and time on power 0.1 sec, 0.25 sec, 0.5 sec and 1 sec as You have described.
I will test this after some days because I havn't working RTD now.
I think that better solutions are to use 0.1mA, 0.2mA or...
pt1000 rtd error
Thank you!
Yes, I'm planning to use schematic on fig.5 / page 4 in AN687 of microchip.
2 OpAmps are used for current generator, which requires Voltage Reference of 2,5V,
for example LM336Z2.5 or other.
1 OpAmp is used to make cable resistance compensation, when using 3 wire...
131 ohm equal to deg rtd
Yes, I read that recommended current for Pt100 is 1 mA (to prevent from self-heating) and for PT1000 0.1-0.2mA (max 0.5 mA to prevent from self-heating). I knew that the recommended current for Pt100 is 1mA, and supposed that is the same for Pt1000, nevertheless that...
pt1000 self-heating
I know that current more than 1mA can cause self-heating... and is not recommended....
But I have a sample RTD Pt1000, which stopped working in my demo/proto kit... I don't know why...
I suppose that the reason is bigger current, but can't understand how it can happen. If...
msp-fet430uif firmware
Is the firmware for MSP-FET430UIF and MSP-GANG430 free?
You can see the schematic in slau101c and slau138b (latest versions) from www.ti.com/msp430/
Chlorine sensor
see this

measurement of free residual chlorine
also you can read this:

you can buy low cost meter for total chlorine CL200... just search in wtih google
uart0 msp430
MSP169 has 2 USARTS - USART0 and USART1.
USART0 can work in UART or SPI or I2C mode.
USART1 can work in UART or SPI mode.
With this device you can use only 2 serial channels according to this.
If you need more than 2 USARTs together with I2C, may be better is to use ARM7TDMI or...
step 1. if you have compilled modules for usb and mass storage device build in kernel skip next commands and go to step 2.
