USB TTL Serial Communication Support

Hello. I am Hakan, an Electronics Engineer with 10 years of experience in embedded system including embedded Linux. I have lots of hands on experience with usb-ttl adapters, serial comms on linux and mcus. I can deliver program with, c,c++ and python. or bash if needed. I can start now. Thank you, greatings

I m a 20 years experience electronic engineer in MCU and PC firmware development, also familiar developer in most popular ARM Cortex-M MCU brands like Nordic, ST, ……etc. and Visual studio developer(VB, C# .net), and Circuit design in Schematic and PCB layout I have good experience in wearable device and usually work with mobile app or IoT for data management, I have a series smartwatch that use nRF52832/nRF52840/nRF5340 MCU and with BLE mobile app pairing, and also nRF9160/nRF9161 for IoT Server connection, our team have professional app/web developer to support us. and for your project, I have many project work on USB to TTL protocol, mainly develop communication between PC and MCU, PC firmware develop in VB and C#, then using a USB to TTL module and connect to MCU UART port. My working base in Hong Kong, have good environment to sourcing in China for lower cost and well communicate to global. Our service including project management, circuit design(Schematic/PCB Layout), PCB manufacturing, firmware development(MCU/App/Web Page/Desktop Application), I sure that can have a perfect solution to you. I look forward to discussing this project in more detail and showcasing how my expertise can bring value to your project.

Hello! I'm Neha, and my team of skilled geeks seems like a perfect match for your project. With a comprehensive background in embedded software development and proven expertise with various microcontrollers like Arduino, STM32, and ESP32 - understanding USB TTL and ensuring proper serial communication is within my grasp. Aside from software, our talents extend into hardware as well to complete the full circuit of electronic projects. I am confident we can identify any wiring setup issues which could be affecting your USB TTL communication setup. Let's get started!

The error message "VBUS_ERROR in a_wait_vrise" typically indicates a problem with the USB host controller, specifically a failure to detect the VBUS (voltage bus) rising, often related to a USB device not being properly powered or recognized. Here's a breakdown of potential causes and solutions: Possible Causes: USB Device Power Issues: The most common cause is the connected USB device not being properly powered or drawing too much power, causing a voltage drop on the VBUS. Faulty USB Cable: A bad or damaged USB cable can cause intermittent or no power delivery. Hardware Issues: In rare cases, the USB host controller itself might be malfunctioning. Pinmux Conflict: In some cases, a pinmux conflict might be causing the issue. Image or Kernel Issues: If you are using a custom image, the USB drivers might be causing the problem.

Hello there, based on your explanation, you need a Windows based program to communication with your device via USB to TTL and using Serial COM protocol. I have made such program using C# and Windows Form. I can help you to make those program for you, also assist you for correct wiring of USB to TTL. Message me if you have any question.

Mi nombre es Álvaro y cuento con experiencia en electrónica digital, incluyendo programación. He revisado su requerimiento y puedo ayudar en: ✅ Diagnóstico y ajuste de la escritura de datos al dispositivo ✅ Revisión y validación del cableado USB TTL ✅ Adaptación de la configuración de lectura/escritura de Linux a Windows Si lo desea, podemos coordinar una reunión para analizar los detalles y ofrecerle una solución eficaz. Quedo atento a su respuesta. Saludos cordiales,

We can help you out in this but for that we need to discuss the real scenario which include sthe hardware and other critical component of ttl communication . We will be highly thankful to consider us once for technical discussion Thank you
