A couple of additional questions:
- Unlike your attached picture, I did not cut the RX to Dig 7 pin. I did a temporary jumper from RX to Dig 9 and I got the result I was looking for. Do I have to cut that line? Will I be consuming two outputs if I don't? If I do have to cut it, what are good ways of doing so (weird question but I haven't intentionally broken features of an IC)?
- Now that I have this data writing to the SD, I will be able to do all the post-processing I want. However, if I want to go a step beyond, what do you think would be the ideal way to use this data for 'real-time' evaluation? i.e. I want to perform calculations using this data to give myself near-instantaneous feedback. I don't suppose I could execute these calculations using data stored on card so will I need to catch it in-between RX and TX, right? Would it get temporarily stored on logging shield?
