Issues with printf function
The C library function printf() is one of the common used functions in embedded systems world to debug the code in real time over a serial connection. Using the printf() over serial is under debate and may not be optimal for embedded systems and that’s what Jacob Beningo over EDN tries...

ESP8266EX and even the new ESP32 SoC lack a USB hardware transceiver, so [CNLohr] decided to develop a USB software stack for ESP8266. After a quick search, I think it is the first try to do a USB software stack for esp8266. USB software stack is a firmware-only implementation of a USB....
Continue ReadingPower supply IC packs eight buck regulators
Aimed at systems requiring multiple low-voltage supplies, Linear Technology’s LTC3374A can be configured to supply two to eight independent regulated outputs with 15 possible output-current configurations. Each of the eight synchronous 1-A buck converters is powered from an...
