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,

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
