The AT Protocol is a common method for communicating with modems for WiFi, Bluetooth, LTE, Cat.M1 via serial protocols. This solutions is the full source code for a UART connected WiFi modem AT Protocol driver, implemented in C and without any delay functions.
This solutions is designed to work with cooperative multi-tasking systems without an RTOS (mainloop systems) such as bare-metal microcontrollers.
The solution handles:
• AT Command transmit
• AT responses with and without payload
• AT Error conditions
• Unsolicited messages from device
• Binary transfer mode
C/C++ header file with some useful macros for outputting colors and font formatting on terminals such as Linux console and Putty. These macros can be used in console applications or integrated in to microcontrollers to give your application more style!
Simple set of macros takes 0 bytes of RAM and 1 function call to printf() per macro.
• Colors: Black, red, green, yellow, blue, magenta, cyan, gray, white
• Foreground colors
• Background colors
• Underline ...
This source replaces the standard printf() and sprintf() functions in the compiler C library with a VERY low resource version with a limited set of features and output types.
Features of tinyprintf include:
• %c character
• %d,%i signed integer (-sign added if needed)
• %s character string
• %u unsigned integer as decimal
• %x or %X unsigned integer as hexadecimal (uppercase)
• %% to write %
Normal printf()/sprintf() implementations on ARM have been measure at ~25K of flash space, using tinyprintf can restore ~23K of flas...
This solution is a set of graphics routines for LCDs.
• RGB color control
• Small RAM footprint 5x7 font with all printable ASCII characters
• Loader for over 50 Adafruit GFX open-source fonts, decoupled from the Arduino IDE and available for any microcontroller.

Fully working Buildroot Linux image configuration for the STM32MP157 DK2 board from ST Microelectronics. This solution uses the 'external build tree' feature of buildroot to allow for a fully customized Linux image without modifying the buildroot configuration. The output image is under 128MB and designed to run from the SD Card on the DK2 board. Excellent starting point for the STM32MP157 family of processors and SOMs or any other ARM Cortex-A7 processor...
Driver for performing HTTP/HTTPS GET and POST operations using the AT Protocol serial modem driver.
This solution is a full implementation of code to GET and POST via HTTP and HTTPS with a remote server over a UART based AT Protocol link. This solution is designed for the BX310x WiFi modem and provides a foundation for developing new solutions for additional AT Protocols on different hardware devices.
Supports loading a buffer for small messages, or callbacks (both Header and Data) for larger data transfers...

C based look up table for a 'breathing LED'. The 'breathing' effect is a non-sinusoidial function, used to add a more organic feel to LED outputs. Includes CSV file for data and C header file to incl...
FLTK is the "Fast-Light Toolkit", a lightweight GUI library for Linux and Windows. FLTK is commonly found on embedded Linux systems due to it's low resource demands and low number of dependencies. ...
