https://community.nxp.com/t5/LPC-Microcontrollers/read-amp-write-SRAM-OM2NTP5332/m-p/1462333#M48872 <P>Hello,</P><P>I have been trying to read and write SRAM data using the LPC55S69 pass through example provided here: <A href="https://community.nxp.com/t5/NFC-Knowledge-Base/Guide-for-using-NTAG-5-with-LPC55S69/ta-p/1114331" target="_blank" rel="noopener">example</A>. The program it selves works, no errors and warnings occur and the green LED turns on when an NFC device is nearing. But when trying to simply send/read data I can only acces the EEPROM memory and not the SRAM, is there a specific app that is needed or is something else not properly setup?</P><P>thanks!</P><P>&nbsp;</P><P>PS. SW3 3-4 is set to on for the VCC and sw6 is set to 5V.&nbsp;</P> Mon, 23 May 2022 09:39:27 GMT StefanC 2022-05-23T09:39:27Z https://community.nxp.com/t5/LPC-Microcontrollers/read-amp-write-SRAM-OM2NTP5332/m-p/1462333#M48872 <P>Hello,</P><P>I have been trying to read and write SRAM data using the LPC55S69 pass through example provided here: <A href="https://community.nxp.com/t5/NFC-Knowledge-Base/Guide-for-using-NTAG-5-with-LPC55S69/ta-p/1114331" target="_blank" rel="noopener">example</A>.
