Especially for the SSP i have looked the user manual a lot of times and yes i can see at diagrams the "continuous" mode for the SSP but i cant find at which register is that option to set it. If you can propose me an reference or example, i would be grateful. I work with this microprocessor and the Lpcopen library 1.03 for two months only, so excuse me if my questions seem "silly" for the most expert users. </SPAN></BODY></HTML> Wed, 15 Jun 2016 17:32:07 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Drive-led-matrix-with-SPI-or-PWM-from-gpio-and-timer/m-p/518238#M2574 lpcware 2016-06-15T17:32:07Z Re: Drive led matrix with SPI or PWM from gpio and timer https://community.nxp.com/t5/LPC-Microcontrollers/Drive-led-matrix-with-SPI-or-PWM-from-gpio-and-timer/m-p/518239#M2575 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by rocketdawg on Thu Dec 12 09:41:35 MST 2013</STRONG><BR /><SPAN>I found an example in examples.lpc1700.zip</SPAN><BR /><SPAN>adc_buzzer/src/freq.c</SPAN><BR /><BR /><SPAN>lib code in</SPAN><BR /><SPAN>mcb1700.code.bundle.lpc1769.lpcepresso/PWM/src/pwm.c</SPAN><BR /><BR /><SPAN>I just searched all files for LPC_PWM1_BASE and found 27 references in one workspace.</SPAN></BODY></HTML> Wed, 15 Jun 2016 17:32:07 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Drive-led-matrix-with-SPI-or-PWM-from-gpio-and-timer/m-p/518239#M2575 lpcware 2016-06-15T17:32:07Z Re: Drive led matrix with SPI or PWM from gpio and timer https://community.nxp.com/t5/LPC-Microcontrollers/Drive-led-matrix-with-SPI-or-PWM-from-gpio-and-timer/m-p/518240#M2576 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by Scorpio on Thu Dec 12 14:32:47 MST 2013</STRONG><BR /><SPAN>Thank you for your reply!&nbsp; I will check them!</SPAN></BODY></HTML> Wed, 15 Jun 2016 17:32:08 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Drive-led-matrix-with-SPI-or-PWM-from-gpio-and-timer/m-p/518240#M2576 lpcware 2016-06-15T17:32:08Z
