read the eva-dts data with Arduino and DDCMP protocol
A PIC18F25k22 development board and HD44780 LCD board along with your ICD4, The embedded system has an analogue input connected to AN4, an 8-way DIP switch connected via the SPI bus and an LCD connected in 8-bit mode to POTR B of the microcontroller. The lcd should initially show a two-line message – ‘Welcome to’ on the top line and ‘Embedded Systems’ on the second line. After a short delay this should change to displaying the adc value on the top line and the DIP switch value on the second line with suitable user interface information telling the user what the display is showing.
I'm looking for an expert in Arduino firmware and driver libraries. The goal is to create a library for a variety of sensors/modules controlled by Arduino Nano.

We already have a few modules done that can be used as template. We are looking for someone who would like keep working with us for more modules in the near future if possible. All your code will be tested with the real modules so you must know how to debug and fix if needed.

Background The future of transportation lies in EVs. Many firms are developing batteries to serve this market best. Almost all-electric and plug-in hybrid vehicles use lithium-ion batteries (LIBs). Despite much progress in battery development, some significant hurdles still exist and must be resolved. Long charging time is the main problem for EV adaptation. The US Department of Transportation reports that battery electric vehicles may be fully charged, using commonly home electric socket level 1 charger in 40–50 hours. Such a long battery charging time is a significant deterrent. Even high current level 3 DC chargers need 30 minutes to charge and require an infrastructure of specialized charging stations. Charging batteries at high currents is a hazard! Cars catching fire while bei...

Dear sir or madam. I would need help with programming. I already have an arduino program for my design (pcb with atmega328 ic) - it is about temperature regulation and also I use 1.3inch lcd display with ST7789 board for showing data. The problem is that if the screen freezes, it doesn’t refresh automatically and stays freezed (I need to unplug and plug again the power). I would probably need separate program for the screen, which would recognize when the screen freezes and then refresh it. Or do you maybe know any other solution? I hope that someone could help me. Have a nice day! Gašper Vidmar
