Arduino for STM32

Sorry for not specifying, for the rush to want to check the pinout on the nucleo-F767ZI. The PeripheralPins.c file is located inside the variant definitions folder, for the bluepill it will be inside the folder ... stm32 \ 2.0.0 \ variants \ STM32F1xx I have just found the ST7735 and the bluepill F1...

I did a little exercise with the Nucleo F767ZI board, I copied all the pin definitions from the STM 1.9.0 core (PeripheralPins.c) and substituted it in the pin definitions from the STM 2.0.0 core (PeripheralPins.c), the NHD screen FT813 of 3.5 " now is answered without problems en el kernel 2....

Reviewing thoroughly, in the STM32 2.0.0 kernel all the pins with all their possible functions are defined. The question is: does a conflict arise when having defined a multiplicity of tasks assigned to a certain pin when we only use it with a specific task ?, such as SPI port 1 with pins PA4, PA5, ...

With kernel 2.0.0 we get ... https://www.mediafire.com/view/9qtc443bj9a25yz I tried both the previous libraries that worked (GFX and ST7735), as well as the most recent ones, and in both cases the same result. Perhaps some special issue with the handling of the SPI 1 or SPI 2 bus, is what causes the...

I suspect it is the STM32 2.0.0 kernel. I thought I had version 2.0.0 installed but it is actually 1.9.0, I checked in the IDE preferences and the json link refers to the previous version: https://github.com/stm32duino/BoardManagerFiles/raw/master/STM32/package_stm_index.json Here the ST7735 + F103C...

I located an old project with a bluepill. I have taken on the task of soldering some wires to connect the ST7735 display. https://www.mediafire.com/view/fup93qjus9j4pqm After a few minutes ... https://www.mediafire.com/view/uzqefqr8vdxevve https://www.mediafire.com/view/bfyiwy7bjv7hytw Somewhat mess...

Don't get me wrong, I have nothing against such kind of wires, they do their job to allow us to test a new component or temporarily wire a some extra component to the project. But: and since we have everything ready, with a single thread that fails! ..., I already saw their faces, because I have bee...

It should be working smoothly. I located a STM32F103VET6 board, similar to the F103C8T6. The programming head has no jumpers, I use a generic STLinkV-2 programmer, with the TFT-MCU wiring indicated above. My suggestion is that you try to get away from the prototype cables and weld everything with wi...

I don't have an F103C on hand, but I do have an F103ZE. Test without putting jumpers on the drip head. That TFT ST7735 you want to connect, it is a SPI screen, it is not an I2C screen, so SCL is SPI-SCK, and SDA is SPI-MOSI. The wiring you should use is: TFT_CS PA4 (spi1 NSS) TFT_RST PA0 TFT_DC PA1 ...

It would help to know more about the sketch you have uploaded. Perhaps a board with higher features like the F407 could be better. There are small format boards with chips like: STM32F407VET6 or STM32F407VGT6
