This project is aimed at replacing/open-sourcing the Logitech presenter. It also contains some features not found on the Logitech Spotlight.

I used a **Seeed Studio XIAO nRF52480 Sense** board, but it required some BSP modification to work with SoftDevice S140 7.3.0. Namely the memory layout:
|
|
```c
|
|
/* Linker script to configure memory regions. */
|
|
|
|
SEARCH_DIR(.)
|
|
GROUP(-lgcc -lc -lnosys)
|
|
|
|
MEMORY
|
|
{
|
|
FLASH (rx) : ORIGIN = 0x27000, LENGTH = 0xED000 - 0x27000
|
|
|
|
/* SRAM required by Softdevice depend on
|
|
* - Attribute Table Size (Number of Services and Characteristics)
|
|
* - Vendor UUID count
|
|
* - Max ATT MTU
|
|
* - Concurrent connection peripheral + central + secure links
|
|
* - Event Len, HVN queue, Write CMD queue
|
|
*/
|
|
RAM (rwx) : ORIGIN = 0x2000E000, LENGTH = 0x20040000 - 0x2000E000
