Re: Arduino (IDE) not showing correct memory for global variables

paulvha, I think you misunderstood my question. I expect the available global memory to go down once I declare my globals. But it does not happen.
The available memory is same whether I declare globals or not.

Re: Arduino not showing correct memory for globals

Below is the output:-
Sketch uses 177840 bytes (13%) of program storage space. Maximum is 1310720 bytes.
Global variables use 14528 bytes (4%) of dynamic memory, leaving 313152 bytes for local variables. Maximum is 327680 bytes.

Arduino (IDE) not showing correct memory for global variables

Hi, I want to check the memory used by globals and wrote the below test code. However the below code shows no additional memory usage as compared to and empty sketch, why? And how to find out the memory used by globals? Thanks and Regards, WI volatile char global_mem[16][40]; void setup() { Serial.b...

Re: Using ESP32 WROOM modules outdoors in sunlight, temperature margin

Where do I see the #define for the max number of nodes in the network?
Thanks

Re: Using ESP32 WROOM modules outdoors in sunlight, temperature margin

Thanks for the quick response. I will do a test to measure ambient temperature in the field to assess the real situation regarding the temperature. Regarding the ESP-Mesh, is there a way to increase the supported nodes to 1200? #define or something like that. Is the code open source? Thanks once aga...

Using ESP32 WROOM modules outdoors in sunlight, temperature margin

Hi, I have a street lighting project for which I plan to use ESP32 WROOM modules. Since the street lights are going to be in sun (summers get pretty hot where these are going to be used), is it okay to use these modules at temperatures of strong direct sunlight, the modules max temp is 85 degrees as...
