I've been making a switching power supply recently, using a boost circuit to increase the voltage. With an input of 18V, the output is 30-36V. However, when the duty cycle is measured at no-load and a...
Manual compilation
When it comes to compiler issues, it must be GNU's famous GCC, which also includes related connectors and assemblers.
The GCC for arm is of course arm-linux-gcc. The version I use i...
