In UDS a maximum of & bytes can be sent. If the length exceeds then how its managed?
Example:
In SID2E, the frame is-
07 -> 2E-> did1-> did2-> data1-> data2-> data3-> data4->
if there are more data bytes present then what will happen?
Who will handle it(the...
I am working on a CAN project with AT89S8253 MCU and MCP2515 CAN Engine. So is there any error which may occur during the SOF bit. Assume the SOF generated after inter-frame-space and while ths bus is idle.
Hello, Is it possible to connect and communicate two I2C devices with each other on the same bus if the two devices work on different speeds?
E.g. Device one is at 100 KBPS and Device 2 is at 400KBPS
Hello FvM,
Actually i am using two master microcontrollers(MDUC812) having inbuilt I2C.
I just wanted to know that If there isn't any hardware configuration taking care of this for me then i have to add some extra code if this condition occurs(Just In Case).
Hello KlauST, you are right.
Hello FvM, I agree with the answer, but theoretically the condition exists. So according to the answer the master sending '0' first wins arbitration. So according to my question the 2nd Microcontroller wins and keeps on transmitting the frame.
But as the 1st microcontroller lost the arbitration...
Hello KlauST, Thank you for your reply, it's very helpful.
But my question was a bit different.
It has two conditions;
a) the 1st microcontroller(Addr-01H) tried to access the slave(Addr-02H)
b)2nd microcontroller(Addr-03H) tried to access the 1st microcontroller
19- There are two Microcontrollers on one I2C Bus (Both having inbuilt I2C) and one slave. The 1st micro controller having address 01, slave address is 02, and other microcontroller address is 03.
Now the 1st microcontroller tried to access the slave at the exact time the 2nd microcontroller...
Hello,
DA A- decimal adjust accumulator after addition.
how the instruction "DA A" is used in 8051 assembly language.
kindly provide some examples with decimal numbers with it.
can it be used to convert binary numbers into BCD?
thank you!
Convert the input number in 16-Bit Binary to BCD and show it on the LCD(8051).
Somehow I do have the assembly code from the internet which is working fine but i do not understand the math behind that. Also i found nothing regarding the math behind 16-Bit Binary to BCD on the internet.
I found...
