Re: STM32F401CCU6 DFU Mode problems?

I had to pull the github repository for pre 1.9.x in order to have proper selection and functioning for my STM32F4xx boards (Both F401 and F411). I'm using the WeAct versions of the black pill F4xx boards, BTW, which have the 3 buttons.

Re: [F4] Neopixel driver using hardware timers

Isn't this similar to how the Octo8211 library for Teensy is implemented? Uses three timer channels to drive 8 GPIO pins from DMA.

Re: STM32F401CCU6

STM32F401CCU6 (and F411xx) are going to be included in the 1.9.0 release. If you git clone the active repository, you can have access to these now.

Re: STM32F411CEU6

Ok... so the first question it's more of just an enumeration than actual physical pins?

And I understand with the clock now. I can override these in my sketch to bump it up to 100MHz if needed, no?

Re: STM32F411CEU6

(Duplicate of my query on issue #722 - is discussion better here or in the ticket?) Q1) I have a question about the STM32F4xx definitions. For example, in Generic_F411Cx/variants.h, it lists one of the pins as: #define PB9 25 // | 25 | | | TWI1_SDA, (TWI2_SDA) | SPI2_SS | | However, the documentatio...

Re: Recompiling library every time??

I blew away my arduino build and cache in /tmp, restarted arduino ide, and now it's caching properly. Sorry for the bother!

Recompiling library every time??

.arduino15/packages/STM32/hardware/stm32/1.8.0/libraries/SrcWrapper/src/stm32/analog.cpp (Note that the "1.8.0" is actually 1.9.0pre from GIT) It seems that EVERYTHING in SrcWrapper is being re-compiled _every_ time I compile a sketch. Isn't that only supposed to compile once and stay in object form...

F411 DMAMEM keyword?

Using STM32duino libs (pre-release 1.9.0 from git) on a "BlackPill F411CE", I was wondering if there were something similar to the DMAMEM keyword that some of the other boards use? I'm trying to move a project from the Teensy3.2 to the F411CE. Thanks!
