Hello,
I am trying to interface an epuck with our custom autopilot through UART,
I used the example from e-puck.org/Downloads/e-puck-latest-svn-trunk/Library
to be able to receive on the e-puck bytes sent from my AVR32 MCU.
I am sending some bytes from our autopilot and I am trying to get them from
the e-puck uart2 to drive the motors.
I checked with the oscilloscope that the epuck is sending bytes from RS_RX
line (connector JE1 pin2, e-puck_c).
Thus the epuck should received bytes on the Rs_TX line (connector JE1
pin12).
However with the example code in my main loop
while(e_ischar_uart2())
{
char c;
e_getchar_uart2(&c);
counter++;
// Do something with c
}
I received only one byte in total
Then the function e_ischar_uart2() always return false.
I did checked with the oscilloscope that there are some bytes sent from my
avr32 on the Rs_TX line.
Is there anything to set on the e-puck to make it a slave ?
Any suggestion on how to debug this communication failure ?
I also saw that in e_init_uart2.s there is this line
.equiv BAUDRATE, 115000
is it normal that baudrate is 115000 instead of 115200 as it is claimed to
be ?
Thanks in advance,
Best
