Re: one download and no more
Hello [mention]Yves13[/mention] There is nothing wrong, actually. :) Once you compile a sketch, such as Blink.ino, with the option <Upload Method: "STM32duino bootloader">, all you need to do is to wait for the message below in the console window at the bottom of the IDE and then just pres...

Re: emulating a OLED display on a VGA and/or a LCD monitor
Timing and synchronizing are always the issue when it comes to TVs, VGA or HDMI signals. In your project, there may be synching issues that lead to broken images on TV or on VGA.

Re: STM32F103C8 BluePill VGA Project
Today I've released a new version of BlueVGA, v1.2. In this version, it's possible to set individual pixels using the new class BlueBitmap . It actually uses RAM Tiles instead of Flash Tile, which in turn allow to set an individual pixel within this tile. There are 256 RAM Tiles, thus, in a 16 x 16 ...

Re: Looking for a suitable SPI slave example/tutorial
Now considering transfering the data over the 2nd SPI to the RasPi as master, and make it display the images through its GPU. The Rasp PI can control the 3d Printer and display everything you need on a HDMI port. Going this way I see no point in using Marlin anymore. This may help you in using Rasp...

Re: Looking for a suitable SPI slave example/tutorial
I have the BlueVGA demo running, and new problem : it runs (with some glitches) on an old LCD monitor, but not on the 52Pi LCD (https://wiki.52pi.com/index.php/7-Inch-1024x600_Capacitive_Touch_Screen_DIY_Kit_SKU:_EP-0084) : it cannot "read" the signal. With TVOut (composite), the demo wor...

Re: Goertzel for stm32f103
The main issue is that you used _N in your code as a variable name while it is a statndard definiton in ctype.h of the toolchain. Simply change it and this will work... Looking at Goertzel.cpp, there may be another potential problem, beside the compiling issue you pointed with _N, regarding CPU Fre...
