A while ago a ordered a Pmod DA4 to use with Arduino and followed this example but when I measure the output with a voltmeter
all outputs read 0V except for the two VCC outputs. This was also verified with a Led between GND the different output, that naturally only gave any light on the same VCC "outputs"
I followed the article in every detail with the connections described below and the unmodified code from the article "uploaded" to the device with Arduino IDE 1.8.15
I also tested to use an Arduino Due that uses 3.3V with the connections also described below,
Finally also used the source code from this article (also linked from the product reference) but still only 0V out from A-E
Since I thought I got a bad chip and the supplier couldn't help me they finally sent me another chip to test with, but the new chip also only gave 0V on all the ports.
What am I missing?
I connected the ports as showed:
Arduino Uno <> PMod DA4
-------------------
10 <> SYNC (1)
11 <> DIN (2)
13 <> SCLK (4)
GND <> GND (5)
5V <> VCC (6)
Arduino Due <> PMod DA4
-------------------
10 <> SYNC (1)
SPI MOSI <> DIN (2)
SPI SCK <> SCLK (4)
GND <> GND (5)
3.3V <> VCC (6)
