Re: Interesting video for linux users about GDB Text User Interface - how about EmBitz

There has been several statements that Windows environment is missing good GDB for STM32duino and how there has been a lot of issues with Eclipse. For reference, please take a look of https://www.embitz.org/ and see how the basic IDE is augmented with a first class debugger that has features not fou...

Re: tiny stm32 F4 boards - how about AnyFC-F7

I am tempted to get a F7 based helicopter flight controller from Aliexpress https://www.aliexpress.com/item/AnyFC-RC-SP-Racing-F7-revF7-Flight-Controller-for-RC-Racing-Drones-better-than-F3-F4/32808317566.html for $32. My hold-back is that I am still learning the best practices for F4 CubeMx HAL and...

Re: tiny stm32 F4 boards

I have not yet accessed the content of the EEPROM - my expectation is that it is empty. Because there is the SD drive, the EEPROM is not the only way to store application data. I like your ideas about the long Dupont pins on both sides. For development and debugging that is the best way. For deploym...

Re: tiny stm32 F4 boards

@ag123, Have you tried those small proto boards with through holes. There it is very easy and fast to solder sockets for multipin components and solder the two-leg components directly. Based on some recommendations from Uncle Google, I did use the wire wrap wires for soldered connections. The stripp...

Re: tiny stm32 F4 boards

I have the same board. Indeed, there are a lot of pins, but I am using most of them in my application. In this application the normal connectors would not work very well. It would be hard to remove the board without bending the pins. My solution was to use the machine pins which do require less forc...

Re: New RPi Zero W - with Wifi and Bluetooth

I think that it is still a challenge at the application level to have USB connection between the STM32duino and phone. In case of FTC robotics, Qualcom has done the heavy lifting and made it easy to develop the robotics application either with Android Studio (Java) or Android App Inventor (graphic b...

Go for the F4 mini version - I am very pleased for it.

Re: New RPi Zero W - with Wifi and Bluetooth

That is the way to go - connect STM32duino products to Android phone using USB. I am a coach for FIRST Tech Challenge team and those small 18"x18"x18" competition robots have been using Android phone as the robot controller starting in 2015. The vendor of the connected I/O modules hav...

Re: tiny stm32 F4 boards

Richard, My reference was for the minimal EXTI usage. My expectation was that it can be done completely in HAL, but I didn't find all the required functions. I had to use LL or direct register manipulation. In the real life applications you are referring, in addition of ADC, EXTI, and DMA, you have ...

Re: tiny stm32 F4 boards

I was surprised about the performance of the OpenMV M7 Camera system. It doesn't make a huge difference, but I think that the camera is using STM32F765VI and not STM32F765VG. The kickstarter info seems to be more reliable than the Sparkfun. The combined price of the camera and F7 module is quite rea...
