RTC Memory Failing? (Arduino IDE)
Posted: Mon Feb 12, 2018 1:13 pm
Hey guys,
I'm using the RTC memory but it's not running as expected. Here's my initialization above setup():
and here's the line of code that doesn't run (it will print "FAILED!"):
Funny thing is that I'm pretty sure it worked before with the same commands... However, if I store all the contents of RTCvals then it works using this line:
Anyway, what's the right way of storing the contents of only one variable to a certain block in RTC mem? I know RTC mem starts at 64 and is stored in blocks of 4 bytes but I'm also fairly certain that 65 should be the next block of 4 bytes. Why isn't it working? Again, I also thought this used to work before. I'm using Arduino IDE 1.8.5 if that helps any.
Thanks!
I'm using the RTC memory but it's not running as expected. Here's my initialization above setup():
Code: Select all
extern "C" {
#include "user_interface.h"
}
typedef struct {
boolean var1 = false;
uint8_t var2 = 0;
uint8_t var3 = 0;
} rtcStore;
rtcStore RTCvals;
and here's the line of code that doesn't run (it will print "FAILED!"):
Code: Select all
if (!system_rtc_mem_write(65, &RTCvals.var2, 4)) Serial.println("FAILED!");
Funny thing is that I'm pretty sure it worked before with the same commands... However, if I store all the contents of RTCvals then it works using this line:
Code: Select all
system_rtc_mem_write(64, &RTCvals, sizeof(RTCvals));
