Re: Planning to add callback to the SPI DMA functions (dmaSend, dmaTransfer...)

If/when you are preparing to port the F1xx architecture to F4xx/F7xx/H7xx, the DMA allocation management has to be addressed. With multiple alternative DMA streams available for the peripherals and more peripherals requiring DMA, the visibility of this mapping matrix is important. In long run, it wi...

Re: Planning to add callback to the SPI DMA functions (dmaSend, dmaTransfer...)

An additional reference can be found at http://www.emblocks.org/wiki/tutorials:f401_f429_disco:spi . I have included the Logic Analyzer screenshots to show how 3 SPI devices are communicating at the same time using DMA for the bulk processing. This is based on the principle that the SPI transfer req...

Re: STM32DUINO - Architecture questions

Some folks I know use "Visual Micro" which integrates openocd/gdb. So debugging should be possible there as well. Haven't tried it myself though, I'm a Unix guy ... I had some sad experiences with Visual Micro. I id use it on several development machines and the Visual Studio underneath V...

Re: STM32DUINO - Architecture questions

The applications cannot be ported between these two IDEs due to different libraries. @Ollie, could you be a bit more specific? You mean that the INO sketch for Arduino IDE cannot be compiled with EmBitz? Not even if one rename the *".ino" to "*.cpp"? @stevestrong, if the INO ske...

Re: STM32DUINO - Architecture questions

The EmBitz is for STM32 development including F4xx and F7xx. The STM32 projects are larger and have more stringent timing requirements. A real debugger is essential for those. @Ollie, is EmBitz supporting STM32F103? Yes, EmBitz supports all variants of STM32F103 processors. In many cases, it is nic...

Re: STM32DUINO - Architecture questions

My two favorite IDEs are Arduino and EmBitz. Arduino is for quick development of small projects for variety of boards - including ESP8266 and ESP32. The EmBitz is for STM32 development including F4xx and F7xx. The STM32 projects are larger and have more stringent timing requirements. A real debugger...

Re: Greetings from Cyprus/Sunderland

Steve, I think that this forum is not the proper place to do transactions between individual forum members. I gave you a description of the problem I have seen in past and missing solution for small STM32 boards. I have limited interest in creating a solution for this specific problem. My preference...

Re: Greetings from Cyprus/Sunderland

Steve,

Thanks for considering this idea. I have not done any SMD work and would prefer to purchase assembled boards.

Steve, In this picture https://github.com/OliviliK/STM32F103/blob/master/BLOB/Images/Blue%20Pill%20with%20terminations.png?raw=true you have the original Blue Pill above. Below that, you have the modified Blue Pill with female pins for the original signals in the blue rows. Next to that at 0.1"...

Re: STM32F746 Arduino Board

My observations and comments are that for the Arduino Uno environment, the users need to have higher performance and pin compatibility for existing shields and for Arduino Mega environment the existing shields are not a limiting factor. The existing shields do require +5V compatibility, which is an ...
