Some people have dog, others own cat. I have freshwater aquarium with fish. Sometimes I forget to feed them in the morning, then I leave the house. So, what is the solution?
Time did not stop. I keep going with the development of my ESP8266 WiFi module's C library. I have now a very well working own HTTP server layer with lots of capabilities. Let's check out my test application.
A few years ago making a hobby circuit WiFi capable costed at least 30$-40$. In the past year Espressif Systems introduced a very cheap and smart solution for WiFi connectivity.
In my old-new blog I am going to present my applications and experiments regarding it's new WiFi product.
CPLD stands for Complex Programmable Logic Device. It is used for implementing logic using macrocells - it has not software, the hardware is "programmed". In the future I need it to adressing an SRAM, which is important for making a CMOS camera working...
In my first English post I want to present you a control circuit I made for a camera crane. At present this circuit drives 2 stepper motors, has USB interface for bootloader and communicates with a radio module - making the control wireless.
