@Kris said in AIN 4-20mA Is this correct?: @fkarner Tak mam podłączone i odczyt wynosi ciągle zero this works for me: [image: 1742568109667-ain1.png] [image: 1742568216110-ain2.jpg]

@Kris You do what it says, check the network and try again or switch everything off, check the network, switch everything back on and then try again.

Hello @Kris thank you for sharing your solution. With 5 V supplied from an external power supply I actually measure about 4.7 V going to the SIM800L due to the voltage drop of diode D1. But yes, that is still out of the specified VBAT absolute maximum rating of 4.5 V. Thanks Felix

@felmue Good idea. Thanks

@iamliubo Hi, Are you interested in writing a program for money? Two signals from the air conditioning remote control need to be recorded. Best regards

Hello @Alex28 in the end pin0 - pin4 are simply Micropython variables, so either switch to the Micropython tab or use Execute code blocks to add more pinX variables. Thanks Felix

I see.

I'm interested too as I have this module. Have you found a way to use it? Regards, Eduardo

@gaviota I know this unit. But I have a unit on the MCP4728 chip. There are python libraries available but I can't make a custom block. Can you?

Same problem here since weeks. It looks like that it is a bug in UIFlow. Because in Visual Studio Code it the upload to the device works well with the same usb driver.

I tested the DAC module. You need to use dac0.writeData (Volt, save = True) in the range from 0 to 2700 to get from 0 to 3.3V. For variable indications to be similar to voltage, they should be divided by 0.00125.[image: 1576164901150-dac-resized.png]
