Driving Servos With STM32F103C8T6

PWM Using Timers The STM32F103C8T6 has four hardware timers that can be used to generate PWM signals to drive servos. Ninjaskit has two classes (Pulse1 and Pulse2) that wrap two of the hardware timers to produce PWM on up to four digital pins each. For Pulse1 these pins are PA0, PA1, PA2 and PA3. For… Read More »

Ninjaskit – STM32F103C8T6 Library

Ninjaskit – A STM32F103C8T6 Library Ninjaskit is a high level C++ API for STM32F103C8T6 micro-controllers. GitHub Page The STM32F103C8T6 micro-controller has 64K of FLASH, 20K of RAM and ticks at up to 72Mhz. It’s quite small ( 7x7mm ), comes with a built in boot loader and is very easy to incorporate in home-made PCBs.… Read More »

Python Code Generators

When confronted by large, repetitive and tedious coding tasks it’s often better to actually write code generators. I’ve written several Python scripts for code generation for different projects and every time it has been totally worthwhile. The entire communications system used by Firetail UAV is automatically generated. Every single piece of information that is transferred… Read More »

StaticString – Beyond Basics

The StaticString library is pretty easy to use, however there’s a couple of little gotchas and interesting points. The first is copying! Copying StaticStrings C-strings are just pointers to character arrays. Creating a new char pointer to the string, of course, will only ‘shallow-copy’.

Modifying c_s2 will also modify c_s1 because they are both… Read More »
