The 30v voltmeter made with PIC16f676 includes schematic diagram and source program.
Smoke sensor design includes principle circuit design, PCB and BOM list
Foreign powerful, simple and portable oscilloscope design (schematic diagram, PCB, program source code, etc.)
A good source code for stm32f4 oscilloscope, which can use 3-channel ADC to measure waveforms and display the waveforms on the screen and also display the amplitude.
The host uses XC2287M and the slave uses MC9S08DZ60. CAN communication is used to realize the basic functions of BMS.
