Gatewares for LimeSDR with GPIO modification Tested up to release 2.23 An overdetailed guide to how a new version has to be created is given in the gateware_GPIO_instructions.pdf long story short: get the new lime gateware and compare the entire src directory using meld to the previous version with GPIO modification, applying all the GPIO-related changes. NOTE: There are two different GPIO firmwares. A firmly modified GPIO firmware that routes the four extra bits in 16 bit mode to the GPIO terminals. And a slightly more modified WFMGPIO firmware that provides the same functionality for WFM playback, e.g. by loading a 16 bit waveform to the memory and again routing the 4 extra bits to GPIO. There is also a LimeSDRmini gateware from mid2018 available that has been sucessfully extended to GPIO. This was actually the first functional test, but the limesdr mini was then abandoned for its poor HF performance. These older files could serve as reference how to do it with the LimeSDR mini. While it was conceptually exaclty the same mod as for the LimeSDR, it was not only relying on changes on vhd files, but also on the graphical layouts that were used for the limesdr mini at that time. E.g. just running meld over the /src directories of the original and modified version is probably not the full story...
