Intoduction: Protecting The Arduino Uploaded Program Codes If you want to sell the final product developed with Arduino, then you need to protect the firmware from cloning. Similarly, you need the protection as well when selling an embedded software by selling the programmed microcontroller chip. Fortunately, there is a lock bits fuse that that is programmable using the ICSP interface. […]

Product Description HMC936D-AM8 is a controller chip for HM-936D digital soldering station controller board. The controller is implemented using ATMEGA8 microcontroller, programmed with lock protection to disable the chip for being read or modified. It runs on 8MHz internal factory calibrated RC clock, so there is no need to provide XTAL and its related capacitors. The operational menu, custom sensor […]

Introduction: Hardware Serial Vs Software Serial Arduino hardware and software development platform provides both hardware serial and software serial communication libraries. Hardware serial communication uses the microcontroller’s internal serial interface hardware that manage the digital signaling on its pin, even computing the parity bit for data transmission or for checking the received data if required (configured), so the CPU can […]

Introduction: Microcontroller Software Design for Complex Processes Designing a software for complex tasks or processes will be easier if we organize the whole tasks into smaller functional tasks, where the tasks communicate each-other through common variables. For a functional task, a concept of state machine has been established for defining and describing the process details, which could ease the implementation […]
