资 源 简 介
Turns STM32F4Discovery board (or any stm32f4/stm32f2 board after some tuning) into SUMP-compatible logic analyzer.
Features
Sampling rate up to 20MHz
16 channels
up to 24k samples
Edge sensitive triggers
RLE encoding of samples for longer runs
USB and UART interfaces for connecting to host
SUMP-compatible protocol
Limitations
Comapred to original SUMP device and it"s clones
* Maximum sampling rate is 20MHz instead of 200MHz
* No noise filtering
* RLE only up to 5MHz
* Channel groups can be only first or first+second
* Triggers are edge sensitive, matching by value is not supported
