Re: [STM32GENERIC] Latest - issues

Thanks. I commented the DMA out. Got then error with missing #define __HAL_AFIO_REMAP_SPI3_DISABLE() CLEAR_BIT(AFIO->MAPR, AFIO_MAPR_SPI3_REMAP) and added it manually. stm32f1xx_hal_gpio_ex.h l.146 /** * @brief Disable the remapping of SPI1 alternate function NSS, SCK, MISO and MOSI. * @note DISABLE...

[STM32GENERIC] Latest - issues

I've updated my local repo copy as there came to a lot of developments in a few last days :) I am currently messing with the BLUE 103ZE variant (see updated BLUE Boards variants in another thread) trying to build the SDCopy demo with F103ZE and SPI/Sdfat. So far I get In file included from C:/Users/...

[STM32GENERIC] BLUE 103/VE/ZE/ZG variants

@Daniel: enclosed are the BLUE 103VE/ZE/ZG variants with updated boards.txt. Plz have a look on it, I've compiled a sketch for BLUE 103ZE and it seems it works. Needs some testing, as usual. Tested on BLUE 103ZET6 72MHz, SerialUSB, stm32duino uploader. UPDATE 22.6.: improved and based on the latest ...

FYI - there are several modifications of the 7735 tft - green, black, red, ..etc. They differ in how they interpret colors, for example..

Re: IDE with Eclipse with Jantje's plugin

Any idea how to measure elapsed cpu clocks under Sloeber in the debugger while stepping through?
Every debugger has got it basically in a small window.. Showing elapsed clocks with conversion to ns/us :(

Could you stream the video from the module w/ FIFO to an sdcard, for example with an lower resolution?

Re: I2C2 on STM32F103C8T6 and HWire

The I2C init comes after the BP plays with USB transistor (in the bootloader or in the serialUSB). So my current understanding is the I2C init (with HWire) is using the P10 "as-is" - that means when set in the bootloader or serialUSB as "output" it will mess the I2C. With sw wire I2C init() sets the...

Re: OV7670, Generic STM32F103RC and ILI9341 display

An idea only - long time back I messed with a Ramdisk module - 8MB one, with only 11 signals lines - 8data and 3controls (plus 3.3V and Gnd).
It was used with retrobsd as swap and ramdisk. The max rd/wr speeds around 10MB/sec. Maybe useful as a frame buffer??
