    manage 12V pulse and 5V pulse on the same pin

    I have Atmel controller which requires a 12V pulse and 5V pulse during flashing. I have a 12V supply and derived 5V from it using a regulator. But I want to know how can I give the 12V pulse and 5V pulse on the same pin. We can manage to give pulse single voltage level using NPN transistor but...

    Problem: Raspberry Pi to NXP MPC5744p over SPI

    Hello, I am currently trying to get SPI data transfer between the MPC5744p and a Raspberry Pi 4 to work. I'm using the SPIdev python toolkit to send the value 26 over to the MPC, using the attached SPItest.py script. To receive this, i've modified the code of the SPI_MPC5744P example to only...

    FIELD ORIENTED CONTROL DISSERTATION

    Hi everyone, I am a final year student who is making a dissertation on Field-Oriented Control (FOC) with a BLDC motor. I am having the issue that with the virus outbreak I have had to modify a lot how to carry out my dissertation. As a result, I do not know what to write about anymore. I would...

    Custom Microcontroller Design Verification And/Or Advice

    I'm working on a custom microcontroller design based largely off of NXP's K64 FRDM boards as part of a larger project, and recently (despite the date on the schematic) finished what may be considered "version 1." As a brief background, this board will have a sibling layout embedded into a larger...

    Improving Embedded Systems Code Quality Using Static Code Analysis

    It’s not a secret that the code quality standards for embedded systems software are much higher than those for games, photo editors and others. The requirements have increased after cases when hardware having got out of control caused a lot of tragic situations and, at best, great deal of money...
