And according to datasheet, DMA can be used with peripheral including GPIO. But there are no any other information, how to use it, what handshaking pins should be connected, etc.</SPAN><BR /><SPAN>&nbsp; My task - to send and receive 8-bit data via PORT0[0..7]. Are there any diagrams how to synchronyze the transface? Any code examples?</SPAN><BR /><SPAN>&nbsp; In my case, CPU will always be master.</SPAN><BR /><BR /><SPAN>Thanks in advance for any info.</SPAN></BODY></HTML> Thu, 16 Jun 2016 02:39:21 GMT https://community.nxp.com/t5/LPCXpresso-IDE/LPC1227-DMA-with-peripheral/m-p/586826#M27380 lpcware 2016-06-16T02:39:21Z Re: LPC1227 DMA with peripheral https://community.nxp.com/t5/LPCXpresso-IDE/LPC1227-DMA-with-peripheral/m-p/586827#M27381 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by kendwyer on Sat Jun 11 16:07:06 MST 2011</STRONG><BR /><SPAN>Check the Install directory for DMA examples, something like:</SPAN><BR /><SPAN>C:\nxp\lpcxpresso_3.6.xxxx\Examples\NXP\LPC1000\LPC12xx</SPAN><BR /><SPAN>The DMA destination address needs to point to the GPIO port you want to transfer to..</SPAN></BODY></HTML> Thu, 16 Jun 2016 02:39:22 GMT https://community.nxp.com/t5/LPCXpresso-IDE/LPC1227-DMA-with-peripheral/m-p/586827#M27381 lpcware 2016-06-16T02:39:22Z
