I just started to swap the hardware abstraction layer that runs the low level stuff on OpenGround. On modern 32 bit processors you usually get a small abstraction library from the manufacturer. This library maps complex commands such as initializing e.g. the SPI subsystem to the underlaying low-level register access commands. For the stm32 series… Read More »
I just uploaded the design files for the pepperF1SH to armattan productions. I ordered frames designed by others in the past, they come in very good quality and the shipping time to germany is quite fast. I think they ship from Taiwan. You can visit my store and buy my pepperF1SH designs following this link.… Read More »

For targets such as the D4R-ii or others using an STM32 processor with the factory programmed bootloader nothing special had to… Read More »

When you buy a BLHeli_S ESCs, the factory has pre-programmed those with the BLHeli_S firmware for you. This firmware comes in two parts, the BLHeli_S bootloader and the main firmware. The bootloader is the code that allows you to upload the latest BLHeli_S firmware using the blheli suite or -configurator. When you build your own… Read More »
