Open amguardia opened 4 years ago
I published the first release. And updated the readme. The library should work with UNO and Mega. I will write an instruction on how to connect the sensor to the board in a few days.
excellent thank you very much. Tomorrow I will try to do the first tests. At the moment I am using the standard SPI pins of the UNO R3 with CS on pin 10 and a 5 to 3.3v level shuttle for all signals
I just tried it with an arduino Mega and it seems to work OK. It didn't allow me to change the Chip select so I had to move the connection to A8 as it was in the example. Look at the output file, there are several values that I do not understand their meaning or in what units are expressed, comments are welcome, but in any case excellent work
Hi!
Thanks for sharing this library. I am using it with an Arduino Mega, connecting it to the Alphasense OPC3 N3 with a shift level converter (the OPC N3 is powered at 5V but the SPI works at 3.3V according to my understanding). For /SS I am using pin 37:
// create new instance (specify SS pin in constructor)
OPCN3 myOPCN3(37);
However, I have not managed to make the alphasense to turn on, not even the FAN. Also, according to the user manual, one should be able to run it in standalone mode without SPI, only feeding 5V between pin 1 and 6.
Does any of this sounds weird to you? So far the Serial output is garble:

Hello Marlon, I’m trying acquire “PM-Data” using your “opcn3-arduino” library and an Arduino micro without success. The SS is the digital pin 12. At the beginning I only get 12:47:17.204 -> Initilize 12:47:18.187 -> Initiating SPI 12:47:20.215 -> Validity: 0 12:47:20.215 -> Serial Number: 12:47:20.215 -> ⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮ 12:47:21.245 -> DACandPowerStatus 12:47:21.245 -> -----DACandPowerStatus----- 12:47:21.245 -> Validity: 0 12:47:21.245 -> Fan: 255, LaserDac: 255, FanDAcVal: 255, laserDACVal 255, Laser Switch: 255, gain and autogain toggle setting: 255 12:47:21.245 -> ---------- 12:47:22.227 -> ConfigurationVariables 12:47:22.274 -> -----Configuration Variables----- 12:47:22.274 -> Validity: 0 12:47:22.274 -> Bin Boundries ADC 12:47:22.274 -> 65535 65535 65535 65535 65535 65535 65535 65535 65535 65535 65535 65535 65535 65535 65535 65535 65535 65535 65535 65535 65535 65535 65535 65535 65535
After a while the fan turns on and I get “0” everywhere.
Do you have an idea, what I’m possibly doing wrong?
Many thanks in advance and keep well!

Good morning, I'm trying to use this Library. I'm not used to programming, I tried the example but the fan didn't switch on. myOPCN3.initialize(); doesn't switch everything on? What is the line to switch the fan/laser on ? Thank you in advance, Best
Hi, I am working with this sensor and I would like to test the library ... do you have any examples for use with Arduino UNO or Mega
