LPC2378 UART restart

zorandjokic — Mon, 18 Sep 2017 09:51:23 GMT

LPC2378 datasheet says that if UART receives framing error, it cannot expect to receive next character correctly. However I wonder if I can somehow restart/reset the UART (after framing error detection), so it can start searching for next character without the burden of previous error ?

Can I simply turn the UART's power off and then on (eg. PCUART0 bit in PCONP register) and then reinitialize UART (baud rate, start/stop bits, ...) ? Although it seems that PCONP does not turn UART on and off, but rather gates on and off its clock signal.

Thanks

Hi,

You could take a look at the following links, as UART-based ISP implementation may provide some guidelines regarding UART usage:

[1] UART ISP implementation on the LPC1768 using the mbed platform

http://mbed.org/cookbook/lpc-bootloader

[2] UART ISP for the LPC1100/LPC1300/LPC1700/LPC2000

http://sourceforge.net/projects/lpc21isp/

[3] UART ISP for the Linux platform

http://code.google.com/p/lpcflash/

[4] UART ISP written in Python

http://sourceforge.net/projects/nxpprog/

[5] UART ISP written in Python for the LPC2000 series

http://sourceforge.net/projects/pylpctools/

Hope this will be useful for you.

Best regards!

/Carlos
