Hi all, i am using silicon labs controller 8051F340 in which the TX of serial port is not giving expected data(acknowledgment for received data). instead it is giving some other data. It is happening only in one particular board (other boards are fine) frame: 55 xx xx xx xx xx xx xx xx xx AA frame sent frame expected: 61(01 is appearing).
i have doubt that the register settings of that particular ctrller has been corrupted please give suggestions to make it proper without changing controller.
Thank You
we think a pin maybe 7 is not at 0v gnd level
pin numbers mean nothing they are package dependent
Ok, and how is anyone other than you going to verify that?
This is your board design, in your possession, you should check the continuity of the ground plane/connections.
Assuming a 48-pin part, where pin 7 is ground.

assume = ASS U ME
yes pin 7 is not connected to 0v gnd supply
code that relies on an instruction-counting
We can only think of one person on this forum who would hide behind a name like that: Erik.
I aint hiding, dunt now what happens

This forum can place the cursor at the name field if the page is slow to load - then it's very easy to start writing in the wrong field.
It's a bit strange with a forum where the name field is open for edit on every post as if Keil intends us to change name between each post.
We know Erik. Only joshing with you.
