After updated to the above firmware, please check your TDSO value for best result. Some users told us they set to 15. In our testing, hw rev 2.2.2 board will likely be 10 or above for parasite mode.
CAI_Support said:We have made watch dog timer larger on WC32 to handle more future functions. We also fixed one I2C issue in some cases for WC32 in this new release.
There is no GUI change since 4.02.09, if you have your own GUI, it can be used without change. WC32 board without WC32IO expansion board will need to add a pull up resistor on the terminal, please see the other discussion about WC32 clock.

For WC8, this fixed an I2C issue with one I2C sensor in certain condition
For wc8 hardware rev 2.2.2 board, please update with this firmware

For wc8 hardware rev 2.3.x board, this is the new version:

These releases are versions without known bug for those hw rev boards. As always, we appreciate all your input and suggestions. Some of those suggestions are in the work. We want to first release these firmwares without any known issue, then move on adding features.

GUI code is same as 4.02.14 level, only if updating from older firmware, you would need to change custom GUI.

We are releasing this new firmware for hw rev 2.2.2 board to add support for DS2438 sensor. Once DS2438 sensor is attached to the 1-wire bus and configured through temp sensor configuration screen, it will have voltage and current reading stored in AIP5,6,7,8 for up to two DS2438 sensors.
For wc8 hardware rev 2.2.2 board, please update with this firmware

This update included DS2438 sensor support. In addition, two PLC commands are added.
V2RH a b c #where a is ADC output, can be AIP5, for example; b is supply voltage to Honeywell humidity sensor, can be 497 == 4.97V, c is result
RH2RHT a b c # where a is humidity reading, b is temperature reading 0.1 degree, 20.1c = 201. c is the temperature calibrated humidity result.
Please provide your feedback. This support will be added to newer WC8 hw rev 2.3.8 board also, but as a user update firmware. Default shipping will still be current 3.03.27 firmware.
Is it possible having DS18B20 and DS2438 on one bus cable (having three leads)?CAI_Support said:We are releasing this new firmware for hw rev 2.2.2 board to add support for DS2438 sensor.
