STM32F103C8T6 Pin Tester to check your soldering

How good are you at soldering?   Here is the STM32F103C8T6  microcontroller board that I use  and have to solder all of the pins. Sometimes when I solder pins to the  board, the connection looks OK and even tests OK with continuity on a multimeter.  However, the solder connections even though they pass those two …

PIR Sensor and Relay Switch to turn on a Light

PIR Sensor and Relay Switch to turn on a Light

Ever wonder how a motion detector is used to turn on a light? Take a look at this graphic (made with Fritzing). It shows the circuitry that uses an STM32F103C8T6 microcontroller to control a PIR sensor and relay switch to turn on a Light. Get the Fritzing source code for the above image HERE (in …

An STM32F103C8T6 based MIDI Controller for MIDI2LR

MIDI2LR MIDI Controller

For those of you who use Adobe Lightroom,  there is a way to use a MIDI hardware ‘box’ to control various Lightroom actions. I am told that once you use the hardware controls you will never want to go back to the software ones. There is a Lightroom plugin called MIDI2LR which interfaces various MIDI …

STM32F103C8T6 Solar Power System Monitoring

If you read my last post on Solar Power System  Monitoring with an Arduino you might be wondering if that circuit could be enhanced a bit. Say, change the LCD to an OLED and add wireless (WEB server) capability? I was not happy to have to go out and look at the device when I …

How a Web Server on an STM32F103C8T6 can be used to control a Relay Switch

BluePill As A Web Server With A Relay

Here is the circuit showing how a Web Server on an STM32F103C8T6 can be used to control a Relay Switch: The Fritzing code used to create that diagram/image can be downloaded here. An ENC28J60 ethernet module is used to connect the STM32F103C8T6 (BluePill) to a network. Here is the source code for the sketch to …

Nuttx on the STM32F103C8T6

Nuttx Configuration Menu

Wouldn’t it be  C 🙄 🙄 L to have a Linux prompt on the STM32F103C8T6.  Not likely, however, Nuttx on the STM32F103C8T6 is about as close as you will get. Nuttx is a RTOS which runs on a wide range of microcontrollers including the STM32F103C8T6. To compile Nuttx for the STM32F103C8T6, a development environment needs …

Turn an STM32F103C8T6 (BluePill) into an STLink Programmer

STM32F103C8T6 as an ST-LINK

It is relatively easy to turn an STM32F103C8T6 (BluePill) into an STLink programmer. All that is needed is a copy of the STLink firmware and a means to flash it. Do a search for STLinkV2.J16.S4 and download it. Flash that binary file into the STM32F103C8T6. See my other post HERE on the STM32F103C8T6 as it mentions …

The Arduino Command Line Interface (CLI)

The Arduino folks just came out with the Arduino Command Line Interface (CLI) : Announcing the Arduino Command Line Interface (CLI) A while back, I wrote about the  Arduino-Builder which is what the Arduino IDE invokes behind the scenes to compile the sketch. (That post is here.) Now, with the Arduino Command Line Interface, everything …

STM32F103C8T6 DIY Programming Cradle

STM32F103C8T6 DIY Programming Cradle

I recently created an STM32F103C8T6 DIY programming cradle. Here is what it looks like: It comes in handy when you need to program a bunch of STM32F103C8T6s. (Note: I made a similar ‘cradle’ for programming bunches of ESP8266s’.  Read about that here.) A standard USB to serial converter is attached to the 6 pin header …

Best Kept Secret

Yes, it is an ambiguous topic. No, I don’t think it should be hidden, however, the fact that this topic does not seem to garner much press could mean it has been a best kept secret. The “best kept secret” is the programming language Forth. For reference, take a look at “A  Beginner’s Guide to …
