C PROGRAMME USING KEIL UVISION AND CUBEMX, GSM&GPS SIM808. ARM CORTEX STM32F407VG,

I am a senior electrical engineer. I have plenty of experience in firmware development and micro-controller developments. I can write the firmware based on Arduino, Raspberry Pi, Pic, Atmega, FPGA, ARM, DSP, PLC and so on. And I can design the circuit by the Altium, Eagle, KiCAD, Allegro & OrCAD, PADs. I provide the services - Gerber files, Netlist generation, BOM generation and 3D Models of PCAD and ECAD. I am also good at AutoCAD, Solidworks. And I can simulate all circuits with Proteus, LT-spice, Matlab, Simulink, Multisim, and Labview as well. Due to my experience in firmware development, I will bring you the perfect result in time with high quality. I will also give you a detailed explanation of the process. Looking forward to hearing from you soon Thanks

Hi, SIM808 support AT command set and those command has to be fed in USART as you mentioned. Are you planning to create own driver for GSM/GPS module? we can support you in this task as we have prior experience in these modules. we also have work experience in similar low power tracking devices. Chat with us to discuss further. Looking forward.

Hi, I am an Embedded System Developer and have an 7 years of industrial experience. I have done lots of project in keil uVision, OpenStm32,Truestudio,IAR Embedded Workbench, Code Composer Studio (CCS) using Embedded C/C++. I have used almost all kind of ARM Cortex M0 - M4 based Microcontrollers like Stm32,LPC148,Tiva TI tm4C123,stm32f4xx,etc.. So this task is very easy for me to complete. I have written lots of firmware in which communicating with GSM Modems like Quectel,SIMCOM and also used GPS Modules from ublox. I will assure you that if you work with me you will have a quality code and on time completion. Kindly contact me as soon as possible to discuss further. Looking forward for a positive response.

Hello! I'm a electronic engineer with experience in (among other micro controllers) ARM cortex micro controllers. Currently I'm working with a same cortex M4 core MCU (STM32F407ZET6 MCU).

I can zoom you to explain everything I did Relevant Skills and Experience We need more info

I work 5 years with STM32F series microcontroller and I used SIM module with my graduate project. You can ask any question for this project.
