Re: trap ICMP ping
As noted above; #define ICMP_IRQ 15 is in the ..\espressif\esp32\tools\sdk\include\lwip\lwip\icmp.h [/i] but i can't seem to find any code that reacts to the ICMP_IRQ or even attach the IRQ. If I send a PING to the esp32 it responds so clearly the IRQ is processed somewhere. Is there any way to mon...

Re: Random String generation
Caution: the code listed above has a bug, it writes beyond the end of the array.

Re: Negative Floating point overflow
I’d be curious to see the expression. Type conversion/promotion/coercion is handled in the compiler.

Re: Saving and writing to eeprom
Seriously??? Save example: #include <Arduino.h> #include <EEPROM.h> // I'm just guessing EEPROM SIZE here #define EEPROM_SIZE 1024 typedef struct foo { char a[16]; char b[16]; } FOO; FOO foo; void setup() { Serial.begin(115200); delay(1000); Serial.println(""); EEPROM.begin(EEPROM_SIZE); // put some...

Re: WiFi - Static IP fails to connect wifi
So, it appears to be a bug in SDK or Arduino core, introduced in newer code than I have installed.

Re: Saving and writing to eeprom
I can’t tell what you are doing incorrectly from the partial code you include here.
What you should do is write a test program to learn how to save and restore using EEPROM. If you can’t make it work, provide the complete code here, maybe somebody will debug it.

Re: arduino sizeof struct
Unless you have good reason, and understand the implications, you should stay away from packed structs.

Re: Saving and writing to eeprom
Esp32 EEPROM is in flash. So is SPIFFS. SPIFFS moves writes around to level the wear, EEPROM library doesn’t.
SD has the same problem with wear, and the same solution: wear leveling. Same thing applies to SSD.

Re: WiFi - Static IP fails to connect wifi
It’s been a while since I installed the esp32 Arduino core, I don’t know how to check the version.
