Generic Containers in C: Safe Division Using Maybe. Martin Uecker, 2025-08-10 I discuss the implementation of type and bounds safe generic containers in C. Previously, I discussed a span type, bounds checking using arrays. and a a vector type. This … Read more
Axel Wagner7 July 2025 There is an idea that is not obvious until you hear about it for the first time: as interfaces are types themselves, they too can have type parameters. This idea proves to be surprisingly powerful when … Read more

Overview The captouch capacitive touch controller allows to convert any FPGA’s IO pin into a capacitive push button. If a finger gets close enough to a touch button the controller recognizes this by a change of capacitance. The button status … Read more
