Problem with serial write
显示 更早的评论
Hi everyone!
I have a problem, that I try to send a command to the MCU (STM32F756), and the transmit is done I checked it with analyzer. But the nothing happens on the mcu site. Howewer when i send the command from tera term it works. What is wrong, is it any properties what i dont know?
serialportObj = serialport("COM17",115200,'Databits',8,"Parity","none","StopBits",1);
%getpinstatus(serialportObj);
%serialportObj.ClearToSend=1
%serialportObj.DataSetReady=1
%setCTS(serialportObj,true);
%getpinstatus(serialportObj)
%setRTS(serialportObj,true);
%getpinstatus(serialportObj)
writeline(serialportObj,'flashmode_on')
delete(serialportObj)

Hi Gyorgy,
I tried the model on F767ZI. Receive the data via USART3 and sent it back via USART 2 when data is available.
MATLAB was used to send the data and Putty was used to get back the loopback data.
It worked as expected.
Can you check in the algorithm do you need
- Flow control which is a name value pair for serialport
- Configure the terminator
