I had a running ethernet board with STM32+ LWIP + dp83848c. Now I did a hardware redesign and brought in a KSZ8863. At the moment IP packets are not passed to stm32. I need some one to implement read/write to advanced control registers of ksz8863 and find out the correct configuration. I can give you remote access to my PC.

I need the design of PCBA/FPGA (Gerber file and BOM)

We have a project where we have the code to communicate with our two devices, but we need to write the "Glue" to combine them together into a USB composite device. Ideally you should use IAR and have knowledge of Subversion. We will use a Nuvoton NUC220 or NUC240. We cannot use a different micro-controller as it requires 5V IO .

I require someone who can design a PCB for my MX Mount Mechanical Keyboard. Preferrable is the use of KiCad. The Keybord needs to be powered by QMK Firmware and be created with a ATMEGA processor, the keyboard will have LEDs and some functions that will be discussed. Someone who can tweak the QMK firmware would be appreciated.

Looking for a code to develop the application, I have most of the logic and have the final product, critical requirement is to interface the code with the hardware. The project may require knowledge of appropriate microcontrollers to run the software on a PC.
