Re: STM32GENERIC, my arduino implementation

I just received small F407VET6 board that has 25Mhz ceramic resonator. Do we have a board variant for this already ? I can try to create one if not. But someone else can decide about the name. Blue 4 Pill ? :-) Size is quite nice as it is only two times the size of F103 BluePill. http://i.imgur.com/...

Re: tiny stm32 F4 boards

Received this small F407VET6 board. Looks like it is well manufactured. The size is pretty much 2x BluePill. I think this must be the smallest I have seen with this amount of GPIO's available. There's also EEPROM and SD card slot. Interesting thing is that it has 25Mhz ceramic resonator. http://i.im...

Re: Platformio

Also they have something called PIO Remote. You can register your devices and give users permission to to access it - remotely that is. By accessing I mean you can flash the remote device and view serial output. Haven't tried it though. Maybe something else in the future..

Re: STM32GENERIC, my arduino implementation

L476RG ah then RAM LENGTH = 128K is wrong also. @michael Did you try my STM32F4 Discovery examples the microphone is working a little bit ... Nice work! I'll have to check that. Just tried this and I can confirm it works. It's fun ! I have to educate myself a bit more about I2S and PDM. Looks like ...

Re: [STM32GENERIC] SPI DMA

Would it be possible to create a test program for one board using SPI1 (master) and SPI2 (slave) to verify SPI and DMA functionality. Test cases could be simply sending bytes and reading them from SPI2. There is one in HardwareTest/SPISelfTest, same-board-test. You need to merge the 2 branches manu...

platformio support

I have been working with platformio integration for STM32GENERIC and now as it seems to be working so I thought to share it with you. My hopes are that it will be added later in the official platformio 'ststm32' platform so that it is easy to use for everyone with automatic package downloads etc. I ...

Now need to determine which of my changes made it.
More to come.
