LPC MicrocontrollersのトピックHaving some problems with writing in the flash from an LPC 54114 over ISP using I2C. https://community.nxp.com/t5/LPC-Microcontrollers/Having-some-problems-with-writing-in-the-flash-from-an-LPC-54114/m-p/661001#M26292 <HTML><HEAD></HEAD><BODY><P>Hi All,</P><P>I have some issues with my LPC 54114 Board trying to program the flash over I2C.</P><P>In my application I am calling the reinvoke ISP command and set it to I2C.</P><P>Afterwards I can speak to the LPC over I2C.
