• Cortex M4 (SIMD) - Fastest way to un-pack 1 (one) uint32 to 4 (four) uint8
    Hi to you all, In my current project I need to send over a serial bus an array of integers: type = unsigned 32 bit integers length = 4096 The driver I'm using (actually USB CDC VCOM from NXP...
  • Change Vector Table in cortex M4 in a persistent way
    Hello, I need to change the Vector Table but I need it to be persistent through a reset, what I'm trying to do is set a vector table duplicate as a safety measurement for reprogramming the original...
  • Cortex M4 (LPC4370): fastest way to sum offset binary samples
    Hi to you all, I'm working on a project involving the LPC Link2 to evaluate its LPC4370 (the one on the board is actually the LPC4370JFET100) for real-time data processing: a more datailed description...
  • CORTEX M4 - Output an array declared with __DATA(RAM) attribute?
    Hi to you all, I'm using an LPC4370 (in a link2 probe) to output the data acquired @ 40 MSPS using the USB CDC VCOM driver included in the LPCOPEN Libraries . I can output an array of uint32_t elements...
  • [CM4] Best general way to handle a hardfault/lockup
    Over the past few months I've been doing a lot of work on a Kinetis K24 processor, which is a Cortex-M4, running the MQXLITE RTOS. It also has a couple other SDKs built in and a surprising level of complexity...
