TouchGFX on a custom made low cost board with the ILI9341 controller over SPI

Introduction STMicroelectronics has spent last couple of years developing their embedded graphics framework called TouchGFX. This very powerful graphics engine makes it possible to include snazzy, smartphone-like screens and widgets into the embedded application, what I feel like becomes defacto a standard nowadays. Along with it, they shipped a lot of dev boards and reference … Continue reading TouchGFX on a custom made low cost board with the ILI9341 controller over SPI
