Logic Analyzer with STM32 Boards

https://sysprogs.com/w/how-we-turned-8-popular-stm32-boards-into-powerful-logic-analyzers/ How We Turned 8 Popular STM32 Boards into Powerful Logic Analyzers March 23, 2017 Ivan Shcherbakov The idea of making a “soft logic analyzer” that will run on top of popular prototyping boards has been crossing my mind since we first got acquainted with the STM32 Discovery and Nucleo boards. The STM32 GPIO is blazingly fast and the built-in DMA controller looks powerful enough to handle high bandwidths. So having that in mind, we spent several months perfecting both software and firmware side and here is what we got in the end. Capturing the signals The main challenge when using a microcontroller like STM32 as a core of a logic analyzer is dealing with sampling irregularities. Unlike FPGA-based analyzers, the microcontroller has to share the same resources to load instructions from memory, read/write th...

Why Those Who Overcame Poverty Have Less Sympathy for the Poor

Posted July 19, 2022 Reviewed by Ekua Hagan Key points People often use shortcuts, such as vivid stories of someone they personally know, to decide how to judge others living in scarcity. One study found that those who "became rich" had less sympathy for those currently experiencing poverty than those who were "born rich." Steve Jobs is an example of a wealthy public figure who came from humble beginnings and was notoriously un-philanthropic. We all love an inspiring success story where the protagonist overcomes adversity, defeats any and all obstacles that stand in the...
