Troubleshooting your ESP8266

ESP8266 module is a great wireless module with some processing power and I/Os. Especially if you are new to it you may find some things not clear enough or struggle while programming, uploading firmware or simply configuring. Rui Santos have written a troubleshooting guide on how to avoid those common obstacles. He talks about where to download NodeMCU flasher, how to configure its settings. Other most common pitfalls also are covered that might frustrate you. Even unbricking of FTDI programmer is covered. If you find yourself in desperate situation when trying to run ESP8266 this troubleshooting list may save you tons of time. Continue reading

Arduino shadows reached FTDI

As you may know FTDIChip makes more than USB to TTL chips. They actually manufacture pretty advanced microcontrollers that are equipped with dual channel USB Host/Device controller. Microcontrollers with code name Vinculum-II (VNC2) have all features you may find in almost any modern microcontroller – these include 16-bit MCU core, 256KB Flash and 16KB SRAM. There are also USAR, SPI, PWM. But of course their strong side – two channels USB that can run as host or device. They decided to make life easier for prototypers by putting MCU in a Arduino like development board. Pin-outs seems to be same as Arduino with 10 more digital I/Os. Hopefully platform is compatible with Arduino shields. FTDI also provides free software that enables compiling C programs. So new Arduino like player with advanced features. Continue reading
