Tutors cover the processors most syllabi use.
| Processor | Topics |
|---|---|
| 8085 | Architecture, instruction set, timing diagrams, interrupts, assembly programs |
| 8086 | Segmentation, addressing modes, instruction set, assembler directives, minimum and maximum mode |
| Peripheral chips | 8255 PPI, 8253/8254 timer, 8259 interrupt controller, 8251 USART, 8257 DMA |
| 8051 | Architecture, SFRs, timers and counters, serial communication, interrupts, assembly and C |
| AVR | Registers, I/O ports, timers, ADC, PWM, Arduino-based labs |
| ARM Cortex-M | Architecture, Thumb instructions, GPIO, NVIC, peripherals in C |
An ATmega328P (as on an Arduino Uno) has a 10-bit ADC (0–1023) and a 5 V reference.
| Question | Working | Answer |
|---|---|---|
| Voltage for an ADC reading of 512 | 512 × 5 ÷ 1024 | 2.5 V |
| An LM35 sensor (10 mV per °C) gives a reading of 61. Temperature? | 61 × 5000 ÷ 1024 ≈ 297.9 mV; ÷ 10 | ≈ 29.8 °C |
| 8-bit fast PWM duty cycle with OCR0A = 191 | (191 + 1) ÷ 256 | 75% |
On an Arduino, analogWrite(pin, 191) gives roughly the same 75% duty cycle. For the 8085 and 8086 side of the syllabus, see microprocessor help.
With a 12 MHz crystal, one machine cycle is 12 clock periods = 1 µs.
| Question | Working | Answer |
|---|---|---|
| Count needed for a 1 ms delay | 1 ms ÷ 1 µs | 1,000 |
| Timer 0 mode 1 (16-bit) start value | 65,536 − 1,000 = 64,536 | FC18h, so TH0 = FCh, TL0 = 18h |
| Baud rate with an 11.0592 MHz crystal, Timer 1 mode 2, TH1 = FDh (−3), SMOD = 0 | 11.0592 MHz ÷ 12 ÷ 32 ÷ 3 | 9,600 baud |
The 11.0592 MHz crystal is chosen because it divides exactly into standard baud rates.
Tutors match your level, syllabus and exam board, from school to PhD.
| Level | What you study | Matching help |

Most lost marks come from programs without comments and wrong address or timer calculations.
| Mark-loser | What to do instead |
|---|---|
| Forgetting to multiply the segment by 16 | Shift the segment one hex digit left before adding |
| Wrong flag effects | Check which flags each instruction changes |
| Uncommented assembly | Comment every line or block |
| Timer values off by one machine cycle | Recalculate and test in a simulator |
| Timing diagrams without T-states | Label every machine cycle and T-state |
| Interfacing circuits without port details | Show port pins and control words |
Microprocessors and microcontrollers is assessed in several formats, and each one is marked on different things. Tutors help you understand the brief and the marking criteria before you start.
| Assessment | What markers look for |
|---|---|
| Theory exams | Architecture, timing diagrams and short programs |
| Lab exams | Working programs on a kit or simulator |
| Lab records | Aim, algorithm, program, result and comments |
| Mini-projects | Working hardware with a clear report |
| Vivas | Confident explanation of instructions and design |
Microprocessor courses use these tools.
| Tool | What it is used for |
|---|---|
| 8085 and 8086 simulators or emu8086 | Running and tracing assembly |
| Keil µVision | 8051 and ARM development |
| Microchip Studio or the Arduino IDE | AVR development |
| Proteus | Circuit simulation with microcontrollers |
| STM32CubeIDE | ARM Cortex-M development |
Microprocessors and microcontrollers is taught to similar core ideas worldwide, but grading, referencing and course structure differ. FLN tutors work from your own syllabus and handbook and schedule lessons in your time zone. Always follow your module handbook for referencing.
| Country | Where microprocessors and microcontrollers is studied | Grading | Referencing usually used |
|---|---|---|---|
| United Kingdom | BEng electronic and computer engineering modules | GCSE 9–1, A-level A*–E; degrees First, 2:1, 2:2, Third | IEEE or Harvard |
| United States | Microprocessor and embedded systems courses in ECE | Letter grades A–F and a 4.0 GPA scale | IEEE |
| Australia | Electrical and computer engineering degrees | HD, D, C, P at university; ATAR for school leavers | IEEE or Harvard |
| Canada | Electrical and computer engineering programmes | Letter grades or percentages; GPA scales vary by province and university | IEEE |
| India | B.Tech/BE ECE, EEE and CSE microprocessors and microcontrollers labs | Board exam percentages; university CGPA, often on a 10-point scale | IEEE |
Students in Ireland, the Gulf, Europe, Africa and Asia can book the same help, with lessons in their own time zone.
The price of microprocessors and microcontrollers help depends on the number of programs and your deadline. A single program costs less than a full mini-project. You always see the price first: a fixed quote for homework and assignment guidance, or the tutor's hourly rate for live lessons, with no contract and no minimum number of sessions. Refunds follow our refund policy.

Used FLN Tutors? Be one of the first to share how it went, in writing or in a short video.
Yes. Tutors explain, write and trace assembly programs with you, within your university's rules.
Configure the ADC, start a conversion, then convert the result with reading × Vref ÷ 1024 for a 10-bit ADC.
A microcontroller has CPU, memory and peripherals on one chip, so it is cheaper, smaller and lower power for dedicated control tasks.
Pulse-width modulation controls average power, for example LED brightness or motor speed, by varying the duty cycle.
Mode 0 is a 13-bit timer, mode 1 is 16-bit, mode 2 is 8-bit auto-reload and mode 3 splits Timer 0 into two 8-bit timers.
Find the machine cycle time, divide the delay by it, and subtract the count from 65,536 for mode 1.
It divides exactly into standard baud rates such as 9,600.
External 0, Timer 0, External 1, Timer 1 and Serial, plus reset.
The 8255 is a programmable peripheral interface with three 8-bit ports configured by a control word.
