how to use #sigrok PulseView to analyze #USB power delivery negotiation. #electronics
on 02025-05-20Initial #buck50 #Sigrok #logic-analyzer #STM32 firmware announcement from 02020. Including discussion of #performance and how it differs from the #ARM reference manual cycle counts.
on 02024-01-28Mark R. Rubin’s GPL "buck50" #Sigrok #logic-analyzer firmware for #STM32 #Blue-Pill #hardware. Also comes with a CLI to puppet it over USB and use it, for example, as a USB UART.
on 02024-01-28#Sigrok can now use #STM32 or compatible #Blue-Pill #hardware as a #logic-analyzer using the #buck50 firmware. 8 channels, 6 MHz, 5000 samples, stored only on transitions; also usable as a 1Msps dual-channel digital storage #oscilloscope with 5000 samples
on 02024-01-28the #sigrok #blog is basically the release notes, which is an interesting idea. At the very least it sets a new standard for the physical attractiveness of free software release notes.
on 02017-02-23#Sigrok also supports SainSmart and other #oscilloscope #hardware, not just the Hantek.
on 02017-02-23The Hantek 6022BE is a 20MHz USB #oscilloscope fully supported in #sigrok that costs US$60. #hardware #pricing
on 02017-02-23how to use the #sigrok #protocol-analyzer with a logic analyzer for #reverse-engineering #hardware. “With fx2lafw, sigrok’s open source runtime firmware, any device containing an [Cypress] FX2 can become a powerful streaming logic analyzer.” Its protocol decoders are in Python.
