Thank you, Alex.Just for clarification — does "Calibrate input channel, the calibration must be done in 2 points" mean that I should connect a known voltage (for example, 5 V) to di...

Hello Alex,Thank you for the information. I tried the firmware update, but it looks the same as before.Board firmware version is 1.4. Without input: With 5V input: After calibration for 5V...

Hi, The latest firmware version is 1.4. Calibration must be done at two points to be complete. The two points must be as close as possible to the two ends of the measurement scale for good results.

Hi Jan, We recently discovered that we have a bug in the firmware, and we took care of it. Please update the card firmware, instructions here. Anyway, for good results, you need to calibrate the c...

Hello, We are experiencing an issue with the measurement accuracy of the RPi expansion board Eight 24-Bit Analog Inputs DAQ 8-Layer (SM-I-022), which is brand new, recently purchased. The board is ...

Thanks for your time James

Hi, IGND is pin 1, and OUT is pin 2. You can vary the schematics as long as current flows from OUT (pin2) to IGND(pin 1).

Good evening, I am a little unclear about the wiring on the above card. The "Quick Start" tab on the product page has the above diagram, but its not exactly clear which is pin one and pin 2. The ...

Thanks.

You are right, the two extra pins are for RGB backlight type display. You can ignore these two pins for the monochrome version. As far as the buy options of the RGB display are limited, the Adafrui...

I have a couple of the SMS display adapter cards for RasPi and am mating these with 2004A display cards. that are said by mfgr to be RasPi compatible. The SMS card has an 18 pin interface, but the ...

My power supply connector on the board was not snapped in all the way for the 24VAC.

Well my Triacs are back to misbehaving again. The triac will close, when it is commanded to, then it will not stay closed. The relay that it is controlling will drop out, then a few seconds later...

I am glad you managed to communicate with all the cards. I did not realise you had no delay between reads. Sorry, the port number does not match the serial port names. I guess you found the corresp...

Configured I2C speed to 400K - no change - test on solidstate output did not roll the leds - leds stayed off - 16relind did not repond. Added 5ms sleep in each iteration of the input polling loop -...

OK, will try tomorrow - 12:30am here in DK :-)

- you found a bug, I will take a look, the 16relind must accept value up to 65535 Hard to answer the questions, but you could increase the I2C speed to 400k and try again with al the cards in the s...

OK, set it up on another Rpi and it seems to work - except 16relind does not allow a higher register value than 255 (8 relays) using e.g. "16relind 3 write 16 on" works. So next question is what w...

You can use any Raspberry Pi that has a 2x20-pin GPIO header, including Zero
