Hi, I am trying to read the RS485 Absolute encoder from EK-TM4C129. I am using the MAX485 module to convert RS485 to ttl, which is half duplex, where DE is Active high, and RE is active low. I have written the code to enable the Transmitter and receiver, where needed. we must transmit the data...

The arm.developer.com states that "At Reset, Cortex-M3 and Cortex-M4 processors always boot from a vector table at address zero". How is it possible that f.e. STM32F446 has the vector table located at 0x0800 0000 address? I know about VTOR, but it doesnt seem that it is used there to do that...

Hello, I am using the Arduino Servo library to actuate two BLDC motors and ADK USB Host Shield to control them using a USB dongle controller (XBOX). But I am facing issues particularly in calibrating the BLDCs and lose the host shield. The most probable problem I could think of is there are some...

Hi all, I'm new here, hope to be in the right place. I'm not skilled at all in the hardware stuff, so I'm looking for help in order to figure out how to solve my problem. Recently I bought a device for photovoltaic monitoring. Unfortunately after the firmware upgrade, the device started...
