From what I understand about VCOM, it automatically adjusts its BAUD rate automatically with the host?</SPAN><BR /><BR /><SPAN>For example, if I connect with my host at 115200, the VCOM port will deliver at that rate. If I change this to 230400, it will adjust to that as well.</SPAN><BR /><BR /><SPAN>What is the upper limit on this? ie, how high can I go through VCOM communication on my host application (java app on a PC) before the LPC4357 can no longer keep up?</SPAN><BR /><BR /><SPAN>Thanks for your help!</SPAN><BR /><BR /></BODY></HTML> Wed, 15 Jun 2016 18:54:42 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Max-BAUD-transfer-rate-over-USB-VCOM/m-p/570981#M18280 lpcware 2016-06-15T18:54:42Z Re: Max BAUD/transfer rate over USB VCOM? https://community.nxp.com/t5/LPC-Microcontrollers/Max-BAUD-transfer-rate-over-USB-VCOM/m-p/570982#M18281 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by rocketdawg on Thu Oct 16 19:40:41 MST 2014</STRONG><BR /><SPAN>it will always be limited by the PC (host)&nbsp; side hardware.</SPAN><BR /><SPAN>the common 16C550 can only do 115200.</SPAN><BR /><SPAN>Some USB FTDI can go 921600 but I doubt that that is the throughput, just the char by char rate.</SPAN></BODY></HTML> Wed, 15 Jun 2016 18:54:43 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Max-BAUD-transfer-rate-over-USB-VCOM/m-p/570982#M18281 lpcware 2016-06-15T18:54:43Z
