How to write/read a float variable to EEPROM
Thanks for your inputs. I tried the below code, compile it without errors, but, with view memory there wasn't anything written in the EEPROM, also I attempted to define the "...

Wrong value reading ADC
Hello all, After all the problems I decided go to the Atmega328P, as I need 2 UARTS I made a switch with a 74hct08 and its working. I just made a PCB to connect an Arduino pro,...

Wrong value reading ADC
Hello all, I used a Arduino Nano on a bread board and run the same ADC code and it gives about 0.005V by bit (long wires etc. and the reading is ok.). I changed the Crystal in the...

Wrong value reading ADC
My multimeter is a Fluke, and I use the 300mV scale. I have 2 Atmega644P and already tried both, the same result. Do you already look to the code I use? Can the code do some...

Wrong value reading ADC
Bobgardner, Thanks again for your interest. I didn't understand what you mean, but, the data sent out is binary data as read from the ADC register. I am reading the data using the...

Wrong value reading ADC
Maximax, The schematic I sent is the circuit I use, but, as I already told, I used a 5k multiturn pot just to make a test. If you look for the schematic the ADC2 there isn't...

Wrong value reading ADC
Maximax, The JP15, JP3, JP4 and JP6 aren't pots. They are pin headers to connect female type of plugs used in aeromodels. Between JP15 and JP3 and the MCU ADC0 and 1...

Wrong value reading ADC
Bobgardner, This pins are pin headers. Pin 1 has the information, 2 is the +5V and pin 3 ground. I use this order because it is the standard in aeromodels like servos, receivers...

Wrong value reading ADC
Bobgardner, I did this change in the code and the result didn't change. It continues to read above 0.030V. uint16_t Read_ADC(uint8_t adc_adr) { uint16_t adc_value =0;...
