Custom ESP32 Firmware

About the project: Requirements are quite clear just be aware about the memory requirements to store 5 images in flash and show 320x480 images. Even using 65536 colors (16 bits), 320*480*2 bytes (16 bits) = 300KB RAM will be required for a single framebuffer, double buffering will not be possible because will exceed the maximum RAM available so, some "flickering" on images update will be visible. To store 5 images on Flash memory (5*300KB) aprox. 1.5MB will be required. The ESP32 (chip) can support up to 16MB of flash but most board manufacturers integrate smaller flash chip sizes. I have several ESP32 boards in stock, also several displays, sending hardware for prototyping may not be required (avoiding big delays to shipping hardware to another country), I could assemble some prototype to emulate your current hardware. About me: I am new on Freelancer.com but I have more than 12-years of experience on Circuit Design, Embedded Systems, Embedded Linux, I have developed dozens of board with SoCs from several manufacturers (NXP, Broadcom, ST, Texas Instruments, Amlogic, etc). I also have a lot of experience developing products for mass production, I can assist you in the manufacturing process too. Some photos of one board that I have designed a few months ago (Carrierboard IEC60601-compliant for Medical Equipment + Bootloader + Kernel + Drivers + Test App): [login to view URL] [login to view URL] [login to view URL] Kind regards,

Hello sir, I have experience in designing electronics circuits and can make your project. i will make your project completely on my side and will deliver a working prototype. I can also develop hardware compatible android and windows based apps. I can show you my previous experience on similar projects. If you wish we can discuss in chat. Thanks

Good day. I have read the details of your project and the document you attached and I understand the scope of your project. I have worked on similar projects using the ESP family of microcontrollers (ESP32 and ESP8266). I am interested in working with you. Please contact me so we can discuss in more details.

Dear sir I have much experience for firmware development. I have done much similar project already. I can show to you my working history(related MCU, TFT...) via teamviewer. Please contact me. Thanks Gao M

Hi, I'm an electronic engineer with more than 5 years of experience in embedded systems development. I'm applying for this project because I have a lot of experience in developing projects based on ESP32 and ESP8266 using ESP-IDF. I have been using different types of LED/LCD displays along with touch displays for developing similar UI based systems. According to your project description attached inPDF, it looks like you need a state machine which would change static images based on interrupts of touch inputs. Alongside depending on the touch input, activate motors using motor drivers. I'm including milestones for each task as follows. I'm very confident about finishing this project successfully and looking forward to hearing back from you. Thank you Anusha
