Hey Guys -
I’m working on a project currently and have hit a roadblock. I’ve got an Arduino Nano which is doing quite a lot (from my perspective) thus not operating at the speed needed. After research, I did change how I lit the LEDs so it’s sent directly to the port which saved a lot of cycles, but am wondering if I can go any further.
To note, when running code with just the 1st step below alone; values are read from the analog pin almost faster than I can read them in serial monitor. When all code is introduced, its read once every 2-3 seconds. I need it to update everything as fast as possible.
The current code is attached, but the loop basically consists of…
- Getting a value from an analog pin
- Does some math
- Checks rotary encoder state
- Lights some LEDs (depending on read values)
- Reads DHT22
- Writes value to servo
- Updates OLED display
If nothing dramatic can be done, any suggestions for a faster microprocessor would be appreciated. To note, it is needed in a tiny space, so the smaller; the better. It also would need to support at least 12 digital & 4 analog inputs. If nothing like that exists, at least I’ve learned a ton from this…
Note: I considered the MKR ZERO, then found out it only supported 3.3V per pin which would call for almost complete redesign of project so prefer not to use it if possible…
