simultaneous setting of GPIO outputs for H-bridge control, how to?

Hi there I am trying to implement a simple stepper motor driver using two H-bridges using ESP IDF. The requirement is that the GPIO's (4 of them) are set simultaneously. My firmware programmer seem to not be able to achieve this. I understand that this requires setting the GPIO's by writing directly...

Re: Do not include WiFi in project

please as well don't forget that there are hardware components other then the plain processor involved which require a defined status like the radio PHY on the ESP.
If your project does not require any of these features you should consider to use another processor family.

Re: WiFi station no longer finds APs after 5 minutes of scanning

I barely remember something that by error if the station does not find any AP after 10 attempts it stops searching. Each attempt is logged and final a log is fired saying that after 10 attempts without result it stops searching

May be that helps, just bean an issue for me like a year ago

Re: Esp32S3 : Why time to write in Flash is so long ? Help !

Dear friend as other have already mentioned fatfs is the wrong way to go with the flash memory. The overhead is far too much. The Xtensa LX7 MCU connects to flash memory in the best case via 8bit SPI sometimes 4bit depending on your package type. Not the reason why it is so slow. However, Flash memo...

How many hours did it cost you to figure the problem out? and did y...
