Been doing some development using VSMicro on VS 2022 for ESP32 and love the tool chain.

But recently I had to switch to ATtiny3216 and found one annoyance that is growing as the code base grows.

Using
Windows 10
Visual Studio 2022 v17.3
Visual Micro 2022.611.2204
megaTinyCore v2.5.11 https://github.com/SpenceKonde/ATTinyCore

The following code compiles and works, but the IDE reports memset as undefined with red squiggly.


Code (]
#include <Arduino.h>
#include <string.h>

void setup()
{
#if defined(_VMICRO_INTELLISENSE)
    byte buf[5):

= { 0 };     // IDE reports memset as "identifier is undefined"     memset(buf, 0xFF, sizeof(buf));  #endif } void loop() { }

Let me know if I missed something.

PS: Switching to ESP32 board does not suffer from this.

Best wishes

Thanks for the clear info. Before we look into this I need to point out that the following code will never be compiled. The define you have used might normally be in a seperate .h file simply to fudge intellisense.

Let us first see if the board actually supports memset. Please comment out the #if and click build.


Code (c++):

//#if defined(_VMICRO_INTELLISENSE)     byte buf[5] = { 0 };     // IDE reports memset as "identifier is undefined"     memset(buf, 0xFF, sizeof(buf)); //#endif

Ok

The following code compiles and I receive "memset worked" in terminal.

Find build log attached.


Code (]
#include <Arduino.h>
#include <string.h>

void setup()
{
    byte buffer[5):

= { 0 };     memset(buffer, 0xFF, sizeof(buffer));      Serial.begin(9600);     if (buffer[0] == 0xFF)     {         Serial.println("memset worked");     } } void loop() {     // put your main code here, to run repeatedly: }

The intellisense issue should be improved in the latest release (22.08.23.00) which is available from the top of the below board:

Thank you for the new release!  :)
Looking good.
