casting pointers

[Stanislav Silnitskiy]

Hello!

I've bumped into the issue with casting...

main.c:
static ble_gap_addr_t addr0;
static uint16_t *p_host0;

int main(void) {
    p_host0 = (void*)&addr0.addr[0];

works fine, but...

beacon.c:
static ble_gap_addr_t addr1;
static uint16_t *p_host1;

void init_beacon(void) {
   p_host1 = (void*)&addr1.addr[0];

hungs in assignment when I call init_beacon() from main()

Where is rake?

Have you found this code in the SDK? Which example are you using?

[Stanislav Silnitskiy]

Hi Andres! its not from SDK. Its my own. Looks like I miss something important...

[Anders Strand]

Can you explain why you are doing this? Also explain what you mean by "hungs in assignment"

[Stanislav Silnitskiy]

as for the address, I just intent to use 6byte address in manner of IP to easily group/manage big net of beacons (project related). Under hungs I mean freezes... I don't have an access to SWD debugger, so my only option to debug is UART line... and I just see, that code doesn't run after the assignment of the pointer in beacon.c

I see. Why is the p_host1 16 bit? The address will be 6 byte = 6*8 = 48 bit. This seems to be a pure C language question. I would advice you to search stack overflow or similar sites.
