Re: GPIO macros for CubeMX

You are correct that many of these read-modify-write problems can be dormant for a very long time and in sometimes dormant forever. What is bothering me, that it has taken some time for STM has some difficulties to get the register names right. F1 has 16 bit registers BSRR and BRR. F4 has only a 32 ...

Re: Alternative BluePill sized F4

There was a reference to 100 pin STMH743 as the next step after F4. Here are some reference points of prices: 1. STM32H743ZI Nucleo board - I got mine today and paid $23 at Mouser - After the purchase, I have seen the prices as low as $19 2. STM32H743ZI chip (144 pin) - Directly from ST for $8.90 (i...

Re: The "PinkPill" board - the Reference Design

I don't prefer to add any more confusion for the F103 family. The "new" Robodyn Black Pill seems to be the winner. The community effort should be for F405 Pill.

GPIO macros for CubeMX

My IDE tool has been EmBitz and that has restricted the development to Standard Peripheral Library. I have tried several non-STMicroelectronics libraries, but with disappointments. In practice, I have now ended in STM32CubeMX with tight integration with EmBitz. The HAL and LL API calls for GPIO felt...

Re: Funny Package

The blue LED is on when PC13 is low (0). My guess is that L on top of C14 is for the user LED. In a similar way, the text ON below 5V is for the red power LED. A curiosity question: do you prefer straight or 90-degree pins for SWD? The package comes with 90-degree which is good for low profile use c...

Re: Funny Package

LED is still at PC13.

Re: Alternative BluePill sized F4

I like this idea. There are several cases where I would like to have something between blue pill (103C8) and blue pad (407VE). When and how I can buy one. Initially, the price is not critical for me.
