Hi, I thought I could reuse PWM code from a USB-1608G module in the USB-CTR04 but get a ULError "Invalid counter device". Is this expected? I was under the impression that the USB-CTR04 had an internal timebase, like the USB-1608G does for PWM generation on TMR0. If it doesn't, is there example python code to show how to configure the USB-CTR04 for PWM generation on TMR0-3? Update: I was able to configure TMR0 on two USB-CTR04 modules as done on the USB-1608 but TMR1/TMR2 (same config) are not working. I think my issue is in understanding external/internal port/channel mapping. If I am reading the internal channel config correctly: for channel in ctr_info.chan_info: if channel.type == CounterChannelType.CTRPULSE: print(f'CTRPULSE Channel(s): {channel.channel_num}') CTRPULSE Channel(s): 0 CTRPULSE Channel(s): 1 CTRPULSE Channel(s): 2 CTRPULSE Channel(s): 3 map to TMR0-3

JRys... Thank you, that worked for my 2-Wire RTD sensors... I had to add one more parameter to turn excitation current on. I am using InstaCal to verify that my python code configuration is working properly. I have a follow-up on my question: I tried to configure a 4-wire RTD, both with InstaCal and python but cannot read temperatures. I noticed that the InstaCal drop has 4-Wire as a "Connection Type", which matches the TempSensorConnectionType.CONN_4_WIRE config parameter. InstaCal then prompts for specific 4-Wire configuration (RTD, 4-Wire (2 Sensors), 4-Wire (1 Sensors) CH2, 4-Wire (1 Sensors) CH3). How would I accomplish this same config using Python?

I'm trying to configure RTDs on a USB-TEMP-AI module. The user manual describes the 2wire-2sensor wiring configuration and mentions that internal connections (T#H & T#H/T#L) are made using InstaCal. I don't see anything in the mcculw documentation that supports this (I'm using the ul.ignore_instacal() mode). The old version of mcculw had parameters that seem to fit the bill but were explicitly removed with the latest GitHub release: ul.set_config(InfoType.BOARDINFO, board_num, channel, BoardInfo.TEMPSENSORTYPE, TempSensorType.RTD) ul.set_config(InfoType.BOARDINFO, board_num, channel, BoardInfo.TEMPCONNECTIONTYPE, TempSensorConnectionType.CONN_2_WIRE_2) Any suggestions or code fragments would be welcome!

I'm struggling to locate the configuration and operating functions in the Python mcculw UL to setup and run PWM on the USB-1608G TMR output. Can anyone point me to example code?

I just saw this thread and was wondering if the DT9829 can be managed with the mcculw Python library? I found out that my USB-TEMP-AI doesn't support PT1000.
