    RS485 communication ground issue

    Its micro-controller based design 1)My question over here. When my test setup is added with Battery charging unit why it fails to communicate. (internal connection shown in thread1) .external wiring shown in thread3). My product is working with aux 85-270VAC/DC connected & 12V battery backup. I...

    RS485 communication ground issue

    I have external connection as shown in Fig. Yes I have made ground common even its not shown in the figure. All ground of Devices and RS485 converter is made common but fails to work when ADM2483 (isolated design ) product used. I have question weather GND isolation can be made common...

    RS485 communication ground issue

    Dear all, I have product which uses isolated and non isolated RS485 communication. I have issue with isolated design. I have used ADM2483 rs485 transceiver for communication. I have setup like this. by seeing this its obvious that unless i have 85-270vac aux supply i will have communication...

    MCP7940N RTC write operation using PIC18F25K40

    yes i have connected properly . because when i tested with arduino uno. it works well. here i have attached waveform for reference. When i connect same hardware with pic18F series .if SDA/SCL connect it will hang. but if i remove SCL line it start continue showing time.But i dint understand...

    MCP7940N RTC write operation using PIC18F25K40

    This make any sense. For Trial what i have done is i just removed jumper cable from SCL line . it continued working where min:Sec sec parameter increment properly . as soon as i connect it start switching from last value and 00 in sec paramter. I thought that we can capture signal from Logical...

    MCP7940N RTC write operation using PIC18F25K40

    I have tested code by changing to 0XDE but didn't worked, with pic18 controller i am getting nack from slave . i have tested my hardware with arduino unop board and its working well. here sample code. I am sure there is no issue with hardware. #include "I2C.h" const int MCP7940_I2C = 0x6F; //...

    MCP7940N RTC write operation using PIC18F25K40

    I have tested my hardware with Arduino Uno board its working well. There i could able to get proper response. i have tested mcc generated library function with ds1307/ds3231/pc8563 module it works well. But when i try with MCP7940N device i wont get any response. #include...

    [PIC] Display DS1307 RTC data PIC18F24K40

    Here is my code where i could able to change RTC value. I have share part of code. DATE_TIME_SET_ADD function where i am changing the RTC date and time in programming mode. when i come out of programming mode means if (pgm_run == 0) if i short (RTC_Write ==1) i.e port pin then only it write...
