Hi Jason,
Thanks so much for this! So far, the TTLs are being sent using the comport file through DirectRT so this is fantastic news. One issue I am having, is that DRT also seems to continuously send the TTL 240 along with the TTL I put into the stim column of my .csv- any reason why you think that might be happening? That is, every time it sends the ttl in the stim, it also sends a ttl of 240.
Also I was hoping to use the ttlecho functionality as well, but again we have this issue with me being unable to put in an actual "loc" line. So if I am correct, I believe that if I create a ttlecho.txt file with "loc","time" it will send a TTL to that location for that time when a correct key response is pressed during a trial? Is there someway to create response-locked ttls in the .csv file instead? Or someway to manipulate the echottl.txt file to send to a COM1 address instead of actual DEC locations? Let me know! Again your help is valued and much appreciated!!
