Hi,
I use STM32CubeIDE and TouchGFX.
Sending to "stm32f746 discovery board" using com port text.
When I send different letters, everything is OK.
If I send several identical letters, the result is with the character ?
example:
asdfghjkl -> asdfghjkl
aaaaaaa -> aa? a? a?
Does anyone know where the problem is?
Part of the code:
if(uartMsgData[0] != 13)
{
uartMsgBuf[msgIndex++] = uartMsgData[0];
}
else
{
msgIndex = 0;
msgRdyflag = 1;
}
