I’m trying to make as precise analog read as possible from my TDS Gravity sensor on esp32 board. I’ve read that the module’s ADC pin is not very precise. So I was thinking about making a average of multiple analogRead(). I made it this way uint32_t Sum = 0; int i = 0; for(i=0; i<10; ..

This is my first time for working with these topics. I want a data structure for packets on ADC data, hence the device is for streaming analog data using TCP and ethernet if it matters. Currently I want to use ModBus TCP/IP, but my concern is on streaming data. my guess is, maybe in getting ..
I am using an hyperspectral sensor from Hamamatsu (C12880MA). So far, I got my firmware done to fit the Atmega328p, timings etc. are working great. But now, I bumped into some issues regarding reading the measurements off the ADC. According to my Clock-Signal generation (at variable f between 0.5 and 5 MHz), I need to ..
I am having trouble get my Arduino HID Axis controller to read correctly in windows. I am using an older version of this code (https://github.com/MHeironimus/ArduinoJoystickLibrary) which I’m modifying to get rid of everything except the axis’. #include "Joystick.h" #if defined(_USING_HID) #define JOYSTICK_REPORT_ID 0x03 #define JOYSTICK_STATE_SIZE 9 static const uint8_t _hidReportDescriptor[] PROGMEM = { // Joystick ..
I have a question for all of you out there is it possible to hold a value in memory after printing it. I will give you an example: Nodered created interface there is a slider with numbers like slider from 20 to 30. you slide it and choose a value like 25 then that value ..
I’m using a CS1237 ADC with an Arduino Mega to look at data from a Wheatstone bridge load cell. I didn’t build the load cell or wire it to the ADC, it’s in a store scale and I just lifted the clock pins of the chip that was controlling the ADC and have been bit-banging ..
I’m using an Arduino Mega to control a CS1237 ADC. I’m sending a signal to the clock pin and after each clock pulse, waiting 1ms and then reading the response, according to the datasheet I found. This seems to be working in some capacity, because when I do Serial.println() for each bit received, and for ..
I have the following problem: I setup the ADC with DMA on my STM32F407 chip with continuous requests. Whenever the DMA conversion complete interrupt triggers, the value in my buffer is always 4095. I verified the reference pin VDDA which is 3.3v and VSSA is tied to ground. I tried single and multi-channel readings and ..
Hallo everyone, I am new into AVR programming and I was asked to develop a board which could read out the values of an analog sensor and set a PWM output. The design included a potentiometer, to act as a percentage dimmer between two PWM signals. As my programming experience is only in the Arduino ..
