Arduino for STM32

I think I need more sleep... I just realized I had been updating the header file without it saving to my arduino folder. It works now! I removed the AFR configuration as well as some of the other setup as it seems to work fine without it. Here is my revised header file: // Graphics library by ladyad...

Hello Everyone, Recently I started messing with a Robotdyn STM32F303 board for a project which I intended to use with my display library. Though, I seem to be having some issues with the macro definitions again :cry: . The STM32F303 seems to be quite different with regard to gpio access. As a result...

Hello Everyone,

I'm working on a project with the Robotdyn STM32F303 Blackpill and I was wondering what the default parameters are set to for the ADC (i.e. Clock Frequency, Sample Time, Resolution). I can't seem to locate this information in the wiki.

Thanks for the help on this guys!
Here's the final version of my ILI9486 library for STM32duino.

I also ported over some popular examples for the Adafruit TFTs.

I did not check all the code anyway did you enabled all the required GPIO clock ? Ahh! That makes much more sense now. I didn't enable the GPIOA / GPIOB clocks in the APB2ENR register anywhere in my code, causing the display not to init properly. When Serial is enabled, it must init APB2 (also used...

Have you tried SLOW_WRITE with 1? I modified write8 for the SLOW_WRITE option using digitalWrite, same issue. So then it isn't the GPIO access method? Revised header file: // Graphics library by ladyada/adafruit with init code from Rossum // MIT license #ifndef _ADAFRUIT_TFTLCD_8BIT_STM32_H_ #defin...

I'm still just kind of dumbfounded at how it works perfectly fine as long as U(S)ART is enabled and there's a Serial.begin() in the sketch. Is there anything else setup / changed when that peripheral is enabled?

I went ahead and revised the gpio access method a little to match some of the HAL based STM32 projects I've seen in the past. Header: // Graphics library by ladyada/adafruit with init code from Rossum // MIT license #ifndef _ADAFRUIT_TFTLCD_8BIT_STM32_H_ #define _ADAFRUIT_TFTLCD_8BIT_STM32_H_ #inclu...

I went through the entire library and I was only able to find some commented out Serial.print() from earlier debugging, which I decided to delete. Here are the two main files: CPP: // Graphics library by ladyada/adafruit with init code from Rossum // MIT license #include "Adafruit_TFTLCD_8bit_S...

Update: I went ahead and swapped the display out with another 3.5" ILI9486 display I had lying around, same issue. I also swapped out the blue pill I was using, same issue. I then tried updating my version of the STM32duino Core, same issue. I also spent some time messing with other upload opti...
