My problem is in understanding the FreeRTOS idle task within Arduino. Searching reveals that FreeRtos uses the standard Arduino loop() as its idle task. It should not. Someone ported FreeRTOS 6 or 7 to libmaple long time ago. I brought that up to date to 8.2.1 and later to 9.0.0, and has been a whi...

Roger how large are the buffers you read from the camera, and how large the one you write to the sdcard? I ask because I have had good luck running the sdfat in parallel with other things with a modified driver that uses the new DMA callback functions, and FreeRTOS. Obviously if the buffers are smal...

I get a feeling all that complication would not be worth it when an RCT or a VCT MCU have many more pins and cost almost the same. I am in the process of building a 3d printer controller board around an STM32F1 or F4 daughterboard (Vxx MCU, replaceable). I am basing my design off the many other exis...

Team FT81x work hard on getting library. Good job porting the library. You could improve the performance of your library with a few small changes, and perhaps be able to play the jpgs with a frame rate more similar to teensy. You have a lot block reads and transfers in loops sending 1 byte at a tim...
Pito can confirm, but I think it was this one: https://www.aliexpress.com/item/STM32F103ZET6-minimum-system-version-STM32-ARM-core-board-cortex-M3/32741572112.html?spm=2114.search0104.3.40.lqwvr8&ws_ab_test=searchweb0_0,searchweb201602_4_10152_10065_10151_10130_10068_10344_5560015_10342_10343_10340_...

I actually had hoped that you would say it's ok to use it
Problem with the SSDs was other types of failures that can happen at any time, rather than wear cells. May be the same case with FRAMs, where they will rather give a limit than say unlimited and then see failures because so other parts of the chip fail.
