Re: STM32F103C8 BluePill VGA Project

Hello! Some News: - I have released version 1.1 with support for Arduino Print Class on BlueVGA. - It's possible to print to the screen in the same way as Serial.print() and Serial.println() - Thus the VGA Monitor can work as an output monitor for Arduino Sketches! - It scrolls the screen automatica...

Re: Problem uploading to STM32F103C8T6 board

My LED is blinking with any combination of jumpers... I guess that's a bad thing then. Most STM32F103 development boards come with a pre installed blink program. I think it is part of QA process. For me, when I open a bag with a brand new bluepill and plug it to USB to turn it on, it starts blinkin...

Roger Clark, the creator of the libary said to do:

SPI.setMOSI(PB15);
SPI.setMISO(PB14);
SPI.setSCLK(PB13);
SPI.begin();

Or:

SPIClass SPI_2(PB15,PB14,PB13);
SPI_2.begin();
This is related to Official STM32 Core.

Re: STM32F103C8 BluePill VGA Project

I'm now working on creating a "dual-core" :roll: version of this VGA library that can be used transparently with Roger's Core and Official Core. This new version is now released. The library BlueVGA 1.0 works transparently for both cores (STM32 and Roger's). The library and source code can be found...

Re: How to disable HardwareTimer on STM32 Core?

Yes it is fixed in the master and will be available in the next release 1.9.0, which will be release in the coming days. I just noticed that version 1.9.0 is released. I just updated my library BlueVGA to verion 1.0 that works transparently for both cores (STM32 and Roger's). The library and source...

Re: How to disable HardwareTimer on STM32 Core?

Is it a bug on the STM32 Core version 1.8.0? Or am I doing something wrong? I checked it on GitHub and it sounds like this issue with analog.h has been fixed in the version 1.9.0 But this version is not available to be installed by Arduino IDE Board Manager... I managed to fix it manually, but I'll...
