Re: trouble with timers and library structure

Well, indeed, you mixed up the STM32DUINO core from ST (available over the library manager in Arduino IDE) with the Arduino_STM32 (Libmaple) core managed by Roger, available only as downloadable ZIP package.
You should only use one of them, delete the other one.

Please turn on verbose mode in Arduino IDE:
File->Preferences->Show verbose output during:. Tick boxes for compilation and upload
and post here the complete message window content.

Re: trouble with timers and library structure

I think this is the environment: Arduino: 1.6.9 (Windows XP), Board: "Discovery, STM32F100RB-DISCVL, STLink, None, None" Arduino 1.6.9. should work ok. Upload via ST-Link (V2?). Just wondering, the Arduino_STM32 core does not have any variant named "Discovery, STM32F100RB-DISCVL". Which target did y...

Re: Ultra simple STM32 debugger

After opening it any further time, unhandled exception after clicking four times on any button in any combination/order. Error message attached. Fields are auto-filled, but the program does not reset anymore. For "pause" it stops and shows the line number, but after further clicks comes the said exc...

Re: Ultra simple STM32 debugger

Same result, no improvement... :( I am testing it with the BP supplied over USB, and a ST-Link V2 clone (connected: GND, SWCLK, SWDIO). SUCCESS! I figured out my problem: I was uploading over USB, so the debug port was deactivated. I wondered why I could also not connect with the ST-LINK utility......

Re: OV7670, Generic STM32F103RC and ILI9341 display

I wired up the SD card, removed the resistors, SdInfo works, so I will check your sketch soon.
Where is the defined readPixels24()? I think it should read and stores 4 bytes instead of 3, because as far as I know the BMP pixel data must be 4 bytes aligned.

Re: Ultra simple STM32 debugger

Unfortunately, it does not work for me. Win 10, 64 bit. I select all folders/bins. As soon as I press any button (reboot, pause, play) the program freezes for ~15seconds, then it shows a corresponding message in the window ("MCU is rebooting... (0x08000000)", "Continuing program execution..."), but ...

Re: OV7670, Generic STM32F103RC and ILI9341 display

You could try to leave the timer settings, just disable the DMA channel //timer_pause(TIMER2); // stop timer dma_disable(DMA1, DMA_CH2); dma_clear_isr_bits(DMA1, DMA_CH2); and re-enable the DMA channel. dma_set_num_transfers(DMA1, DMA_CH2, 2*PIXELS_PER_LINE+1); // 2 readings for each pixel dma_clear...
