spirilis 1,263 Posted February 3, 2016 ok , this is >fantastik< , but why ? (i hope im not beeing an AHolle, asking this) Not 100% sure. Something about the Linux cdc_acm driver having a bug or not working right with "composite" USB devices. Share this post Link to post Share on other sites

ki01 0 Posted April 19, 2016 Hello, new guy here. I can't get it to write aswell :/ Just trying something super basic for the first attempt: void setup() { Serial.begin(9600); } void loop() { Serial.print("Hello World"); } COM is detected by both windows and Energia, it compiles without errors and the baud rate is set in the serial Monitor, tried to change the pins on J3 ( horizontal and vertical positions) and PuTTY incase the inbuilt Energia monitor was the problem. NOTHING. can't get it to do it. I got some basic led flashing in another code running, so the chip isn't dead and i also tried it on two computers with both usb3 and usb2 sockets. the USB cable that i use is 1.8m long but i refuse to believe that it could be the cause.

sicksame 0 Posted April 24, 2016 I have a strange problem with my MSP430G2553 Serial Monitor. It is rev. 1.5 so I did change the UART pins to vertical, but whatever I want to post to serial monitor I get some random symbols (like it would do when the baudrate is wrong). How do I know that everything with baudrate and COM is right? I have two MSP430G2553 and the other one works with no problems at all. Maybe I need to reset something or whatever? I have no idea what to do other than change the MSP430 for another one. Thanks. Edit: I just changed the MSP to another one which worked. I asked my professor about this and he said it is due to some frequencies in the controller itself. Had no time to go in depth with solving the problem with the controller.

cjcj1949 0 Posted April 23, 2018 Using the FR4133 launchpad I found that the red led seems to use the serial port. Using the red led as an output stops the serial output. Share this post Link to post Share on other sites
Rei Vilo 677 Posted April 24, 2018 @cjcj1949 Please refer to the pins map of the MSP430FR4133. All the pins maps are available at https://embeddedcomputing.weebly.com/launchpads-and-boosterpacks-pins-maps.html and http://energia.nu/pin-maps/. Share this post Link to post Share on other sites
cjcj1949 0 Posted April 24, 2018 Should I have referred to it as P1.0, TXD, LED1, RED_LED or P1_0. The blink sketch just uses RED_LED. Share this post Link to post Share on other sites
