TIM6 and TIM7 slotted non-blocking delays
An array that offers "slots" for the non-blocking delays you need in your program. Before including the header of one of these two libraries, you have to define the size of the array that means, the number of the delays you need. TIM6 or TIM7 are used as counters at a frequency also defined by … Continue reading TIM6 and TIM7 slotted non-blocking delays
VPC version 3.3.3 update
Small additions, changes and bug fixes. Some triggered a revision and regeneration of all the libraries and the example projects. There are also two new libraries and a demonstration project for them that deserve their own articles. Additions When generating the code, VPC adds some clock values (from the clock settings window) on top of … Continue reading VPC version 3.3.3 update
