![]() Next in the search was an LCD with HDMI input. However, the very nature of Open Source Software means that there is always someone willing to put in the effort and dedication to make things work and this card is no exception with support being provided by Matthias “Hias” Reichl at Įncouraged by this level of support I went and purchased the card and will document in subsequent updates my success or otherwise in integrating the card. Be warned though support forums are awash with complaints about how poorly the device is supported and that drivers don’t work properly. ![]() The only such card that I found was a Cirrus Logic (formerly Wolfson) device from Element 14. While there are a number of Hardware Attached on Top (HAT) options for HiFi grade cards for the Pi, the options for such soundcards with a microphone/line in input for the Raspberry Pi are somewhat limited. To keep things compact I searched for suitable sound card that utilised the GPIO pins. Any soundcard will therefore be an external device connected either through one of the USB ports or the GPIO pins. ![]() The Raspberry Pi on all versions has neither of these features for reasons of cost and simplicity. FeasibilityĪ quick google revealed that it should be well within the capabilities of the Pi 2.Īn obvious prerequisite for data modes is to have both a microphone/line in input for decoding and a line out output with reasonable fidelity for modulating the transmitter. To see how small I could build a data mode decoder running flgigi with appliqué sound card and small LCD for portable operation. I have shelved these projects for the time being. After building my OpenElec media box I purchased another Raspberry Pi 2 that I had planned to either turn into an ADS-B receiver or a weather station data logger.Īfter a bit of thought I decided that a Pi Zero would be more suitable for the weather station logging and the ADS-B receiver would require the setting up of another antenna which I don’t have space for.
