Arduino for STM32

My experience has been that when something doesn't work, it's because of something I did wrong or misinterpreted. I wanted to put out a sanity check before posting an issue on GitHub.

This seems to be a problem similar to the one posted by ahorow, "Write to Ethernet truncated using EthernetWebServer_SSL_STM32 library". I am attempting to write a file found on an SD card to a connected Ethernet client. The file opens fine, and I have no problems writing to the client. Fo...

Did you ever resolve this issue? I am running into the same situation also with the Nucleo-767ZI board and both the SdFat and standard Arduino SD libraries. Are you also using the SD libraries?

Thank-you fpiSTM and khoih-prog for your help. Unfortunately I do not have another board with networking capability available for testing. I did spend some more time on this but still no luck. I did cut out unused code from the original listing and spent more time educating myself on this topic. Ple...

So I assume that I would need to use the SSL version of the web client for this site? Please bear with my ignorance on this topic, I'm doing my best to come up to speed as I go along. I have used an example from the library EthernetWebServer_SSL_STM32 and adapted it for my own application as a start...

Hello all, I am attempting to read the weather feed from Environment Canada using the AsyncWebServer_STM32 library. My code is based on the WebClient example included in the library. I only made the minimum changes necessary. This is a file that is periodically updated by Environment Canada and made...

UPDATE - I did finally get the 'BLINKY' example working. I changed the 'Optomize' setting from 'Fastest (-03) with LTO' to 'Smallest (-Os default)'. Thank-you for looking at this issue!

I assume these are the setting you are looking for? Please see the attached screenshot...

The simplest sketch I used is the Blinky example: /* Blink Turns an LED on for one second, then off for one second, repeatedly. Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to the correct LED p...

Greetings, I have attempted to build a number of examples from the library 'AsyncWebServer_STM32' (https://github.com/khoih-prog/AsyncWebServer_STM32) for the NUCLEO-F767ZI. I followed instructions to the letter and code built successfully and uploaded fine, though there was no activity on either th...
