embedded c

There is a simple project I want to build which consists of five buttons and five leds, two of the buttons that I want to stick to PORTA, require pullups to work as they share a common ground while the rest of the three buttons on PORTC doesn't need pullups. The problem that I am facing is that...

I am currently trying to develop a pulse oximeter. For this I use the MAX30102 sensor and the NXP LPC1768 microcontroller. The communication is done via I2C. I have configured the MAX30102 sensor to generate an interrupt as soon as the FIFO is full. As soon as I start the program in debug...

We have hydraulic steering system with small motor atop it. This system will be mounted in about Five truck models. All truck models will have same steering software but different values for calibration parameters. Supplier will deliver steering ECUs to OEM manufacturing with steering software...

note : 5 channel flame sensor is used which is mounted on the end effector of the arm,and the robotic arm scan does 180 degree scanning...So experts you are all in here.. hey listen m also using PCA9685 Servo motor driver to control the robotic arm ,,,i just only need the help in following /...

Can use a pointer to access content of the memory location on embedded c. I need to write a program that add two numbers stored in memory location. int *p; int *q; p = (int*) 0x30610000; q = (int*) 0x30610004; int sum=(*p)+(*q) Is the above code correct? I need understand how access a content...

In my one project i want to give some serial number and want to store it in the flash for the first time while flashing. I don't want to build the project again for updating the serial number. Is it possible to update the address location in .bin using any tool command line and flash the...

Hi, In my first job I have worked as an Embedded systems engineer (with major focus on software) for 1.5 years. I am currently working as a hardware engineer for 2 years. Considering the long term success, is it better to specializing in one area( Specifically analog electronics or...

Hi, I am currently working with a sensor platform to measure IAQ. One of the sensors that I am using is the ZMOD4410 developed by Renesas to measure TVOC. I am having trouble with the sensor's I2C. In the datasheet it says that the implemented transmission protocol is similar to conventional...

I currently have a custom PCB design using the PIC16F1937-CN. The custom circuit gives an output voltage via the usb to an external device. I would like to charge my circuits battery with the same usb port which is currently not the case. It has another port for charging the device. What design...

i am facing problem while programming PIC16F18875 using pickit3. I am using mplab x on windows 10. I bought new chip and and from first i am getting problem. currently i am giving power from pickit3 which is approx, 4.5V. I checked the connection for MCLR, VDD, VSS, PGD and PGC pin. I have...

I am planning to start manufacturing of smart locks and smart bulb that are integrated with tuya application. How should I make a circuit? I need help regarding designing and manufacturing. How should I manufacture driver?

Hi everyone, I am a final year student who is making a dissertation on Field-Oriented Control (FOC) with a BLDC motor. I am having the issue that with the virus outbreak I have had to modify a lot how to carry out my dissertation. As a result, I do not know what to write about anymore. I would...

Hi all, I am fairly new to embedded control systems, for which I am using a PSoC 5LP to implement closed-loop speed control. I am currently working out the code for the PID controller and this is the following code I have (in C): P = Kp*error; I +=ki*error; D=Kd(error-last); PID=P+I+D; Now, I...

I was tasked with creating a certain 8051 microcontroller project by my professor and I am keen to build the project all by myself, however, in order to carry out the given assignment, I may need some expert guidance. The project description is provided in below paragraph. The microcontroller...
