jmparatte 0 Posted January 6, 2014 Share Posted January 6, 2014 I'm developping some codes with Energia or TI CCS for the TI LaunchPad MSP-EXP430G2, v1.4 and v1.5, with G2553 and G2452 chips. I organize DIY workshops. I'm playing with various computers, I enumarate them: 1x W7Pro32, 1x W7Starter, 1x W8.1x64, 1x TP-Link TL-MR3020+OpenWrt, 1x TP-Link WR710N+OpenWrt. Nothing is going right with serial, only my old W7Pro32 can read/write thru the USB serial ! Even my 2 OpenWrt TP-Link can't communicate ! If I play with some Arduino in place of TI LaunchPad, all USB serial is working fine (except the known reset problem of Arduino USB serial). Yesterday evening, I played a lot with a TI LaunchPad and my W8.1x64. I discovered that sometimes, the serial USB could communicate ! That's after a lot of stress of the serial settings. I used PuTTY to receive something. The G2553 program was continualy sending 1 character every second. After changing the "Flow control" in PuTTY/Settings/Connection/Serial a lot of times, changing from XON/XOFF to RTS/CTS to /DTR/DSR, in any order, and typing a lot of ^S,^Q,... sentences, the TI Launchpad would finally communicate ! As soon as the USB serial communicates, I can deselect the "Flow control" (can be any) to "none". But never unplug the USB else... What is wrong in the firmware ?
