What We Do
Firmware Development for Board Support Packages and Application
 BSP (Board Support Packages) will be developed for any micro controller and customized based on requirement.
 The below BSP are developed for the Microchip 16 bit family Micro controllers.
a. Microcontroller Clock - Driver to initialize the micro controller Clock at different clock frequencies
b. Sleep and Wakeup Module – The sleep and wakeup drivers implemented for power saving when the
module is not active,
c. Digital (DIO) Module - Software module to read the digital input and control the digital outputs.
d. Analog (ADC) Module – Software Module to read the Analog input with 12 / 10 bit ADC.
e. Timer Module – Software module to initialize the timer for 1ms, this is the basic OS scheduler.
f. CAN – Software module to perform the CAN communication used in Automotive applications.
g. UART – Module to perform the serial communication.
h. SPI - SPI drivers to read and write data into EEPROM memory to store non volatile memory.
 The Application Software on microcontroller platform will be developed based on the requirement.

What We Do
EOL / UDS / OBD2 Software Development
 Software development for UDS and OBD2 protocols for EOL (End of Life) tools
using CAN (Controller Area Network).
 CAN driver development and CAN TP protocol development.
 UDS protocol developed and tested for the following below services
a. Default, Programming, Extended Sessions. (0x10 service)
b. Read By Data Identifier ( 0x22)
c. Write By Data Identifier (0x2E)
d. DTC logging (0x29 Service)
e. Clear DTC (0x14 Service)
f. Flashing using UDS protocol. (0x36 Service)
 OBD2 services implementation.
 EOL hardware tool development to include the Keypad and Graphical
display.

What We Do
Motor Controller Software Development

Projects www.leadembedded.com
Buzzer / Relay Project
The project is switching ON the Buzzer and Relay based on the operational switch,
If the switch is ON for a duration of time in hours operated either continuously or intermittently.
Scope of Project: Proto Concept Development of the Hardware and Software.
Micro : PIC Microcontroller.
Software Modules Developed:
 Internal clock for 20MHz
 ADC Module for checking the voltage and taking a decision
if the operational switch is ON / OFF
 Digital Module to interface the switch to reset the number of
hours.
 NVM Memory for storing the number of hours the operational
switch is ON.
Hardware Schematic Design:
 EasyEDA software used for schematic design.

Projects
CAN Driver:
CAN driver development for microchip dpsic33ev256gm106 at 500 KBPS
a. Transmit of CAN messages at 1sec periodicity.
b. Reception of the CAN messages.
c. Loop Back of CAN Messages, transmitting the CAN messages received from the CAN tool.
The CAN tool used is Microchip CAN Bus analyser. The MCU is the MCLV-2 board.

Projects
PWM Driver Development:
The PWM is configured for 10Khz for motor driving in centre aligned mode.
Total of 6 PWMs are driven and different duty settings based on the CAN command.
PWM1H, PWM1L, PWM2H, PWM2L, PWM3H, PWM3L are the pwm channels.
If the CAN command requests 50% duty cycle, the board is configured for that duty.
Other driver development like Digital Input, Analog InputOutput are completed.
