![]() (click RAW button at bottom left to disable protocol decoding) Third, Remove any UART Rx and Tx block from your model (sharing same UART pin than the one use for Ext-Mode), just keep the UART config block which will be used by the External-Mode. Second, Does matlab handle properly COM port with your setting: Make the same test from MATLAB using blockset “picgui” interface. If you do not have a terminal installed, go directly to the Second step. Once your model is running on a board, connect to the target with either your preferred terminal (free ones like realterm, teraterm) and verify the model behavior. Such model should send continuously on the Tx pin the latest value 1 received on the Rx pin. First, I suggest you to use a standalone model with the simple UART Tx-Rx model as shown above. If/Once validated, go to the ‘Last’ section below. (I am not clear if that is done on your side). Validate your hardware setup and UART connection WITHOUT EXTERNAL-MODE. Hi Hassan, I am not completely clear about what works and what does not work. I cant upload image or matlab file to become easy to understand which is need permission. BTW COM11 is same COM as in the device manager window. Is that mean matlab is not seeing COM11 as the required COM? if so why in the External Configuration COM11 is the only COM available. Starting programmation of Micros.hex on 33FJ256GP710A = In external mode configuration the COM11 is appeared while in the command window, Matlab trying to open COM0. If this is the case, you may need to re-start MATLAB. Possible causes are:ī) The specified port number is not correct.Ĭ) The specified bit rate is not supported by the host machine.ĭ) The previous connection was not closed correctly. ![]() #Exe attempting to run matlab r2015a win 8.1 codeThe reported error code is: 2 or 0x00000002. #Exe attempting to run matlab r2015a win 8.1 serialOther thing i notice following comment in the command window: Failed to open serial port '\\.\COM0'. Only TX and Rx blocks which are uploaded to the target but when i chose connect to the target i got same error. I got same error when i did what you said. Then open a terminal (RealTerm, TeraTerm.) and check that you get back ‘b’ when you press ‘a’…No others ideas to check so far. For further help, please post your model or at least a screenshot with the complete report you obtain.
