I am using a PIC18F26K83. I want someone to create a simple can bus system where the mcu you will send can messages depending on what can message it receives.

i want you to give me suggestion of hardware and write me programm code. i want to plug in 1wire temperature sensor DS18B20 in hardware and need software which reads 1wire, which checks that it works and gives out temperatur range -20°C until +40°C in 0,2V - 4,8V. if there is error or sensor has problems he should output 5V. i pay 100% after finishing whole project successfully.

I need a component with laser beams that cross at very precise intervals. The interval timing must be precise at the microsecond level if possible. The pulse timing interval will be the same interval for the on/off states. The pulse interval should have two modes. In the first mode the lasers should go on/off simultaneously. In the second mode the lasers with switch on and off. When one of the t...
