CH347 Programmer Drivers and Software for Windows

Now that we’ve explored the hardware aspects of the CH347T-based programmer, it’s time to dive into the drivers and software that bring this device to life. While the hardware offers substantial improvements in terms of speed and functionality, its true potential can only be unlocked with the appropriate software tools. This section will guide you through the installation process of the drivers and examine the software options available for interacting with the programmer.

One key consideration when using the CH347T programmer is the compatibility of the software and how well it manages the various serial interfaces it supports, including UART, I2C, SPI, JTAG, and SWD. We’ll explore Windows only tools, focusing on how they handle specific tasks such as memory programming, serial communication, and debugging.

CH347 Fast USB Programmer Schematic and Review

There is a new product on the cheap serial programmers market. Nanjing Qinheng Microelectronics Co., Ltd. (the same company which created CH341A under the brand WinChipHead) released a new and improved USB interface IC: the CH347. Zigong Yaojie Electronic Technology Co., Ltd. used this chip to make an upgraded serial memory programmer. To be more specific, they used the “T” version (CH347T) for a cheap programmer in a similar shape and size to the well known CH341A Mini Programmer.

So, is it worth to switch to CH347T programmer? If you’ve previously used CH341A Mini Programmer you may know it had some voltage levels issues (not the IC itself, but the programmer by design). It’s time to analyze the new CH347T programmer to see if old issues were fixed and what new limitations come from its currently available version.

XTW100 Mini Programmer Usage and Tests

Long time ago I got an XTW100 Mini Programmer and because it came without documentation I began by analyzing the hardware which resulted in tracing of its schematic. This is yet another cheap Chinese serial programmer for I2C and SPI memory chips based on STM32 microcontroller. Last time I managed to break its firmware by attempting to read it from the microcontroller. However, I got a new programmer and I’m ready to do some tests with it.

This time I will stay away from the programming port to avoid firmware damage. I will therefore focus solely on using it for the intended purpose: reading and writing memory ICs. I got myself two chips, the I2C EEPROM 24C02 and the SPI flash memory which will be used for tests. I talked about the software utility which you can use with this programmer in a previous post.

Basic Homelab running on low power NUC

 Generally speaking a Homelab is a personal, non-commercial environment where individuals can set up, experiment with, and manage their own IT infrastructure. This can include a variety of hardware and software components, such as servers, networking equipment, virtualization platforms, storage systems, and more. However most people only need to host a few services such as home automation, personal websites, media servers or backup and storage.

There are plenty of videos on YouTube where users are showcasing their homelab setup, some of which are pretty advanced setups with rack-mounted servers and professional-grade networking gear. In fact, most users will never need all these and when you start a homelab you begin with a list of services you want to host.

Install Home Assistant Container on Orange Pi Zero 3 (part three)

It's been a while since I began experimenting with Home Assistant (HASS) running on single board computers (SBCs). The main advantage of using an SBC for HASS is achieving good performance with low power consumption. However, most modern mini PCs offer better performance over a SBC while requiring only slightly more power. Additionally, mini PCs come preassembled with all necessary hardware, unlike SBCs, which require separate purchases for cases, power supplies, and storage. I plan to migrate my Home Assistant setup to an Intel NUC eventually.

Until then, I'll continue this series on setting up HASS on Orange Pi SBCs. The container method for HASS is similar across different hardware and operating systems, though Docker installation methods may vary.

Install Home Assistant Core on Orange Pi Zero 3 (part two)

Some time ago I decided to get Home Assistant (HASS) running on a single board computer (SBC) without knowing too much about this software. As I soon found, Home Assistant is complex software and there are multiple installation methods, more or less available depending on target hardware. In short, I got an Orange Pi Zero 3 SBC with 2 GB of RAM which I intend to use as a local home automation server.

Although the SBC has sufficient processing power for Home Assistant, I shouldn't expect too much from the limited SD card storage. I decided to give it a try anyway since I really like the small form factor of Orange Pi Zero 3 (it can directly replace the old Pi Zero with only 256 MB of RAM I am currently using for hosting a local MQTT broker). Although this guide is targeted at this specific SBC, it is very probable that you can install HASS on similar Linux platforms using the same commands.
