Hello everyone, I am new to the forum and I have some problems with openlog currently. I am connecting the oplog with arduino uno ([openlog-uno] VCC-5V, GND-GND,RXI-TX(digital pin1)) just like the sparkfun tutorial. The sd card is recognized and successfully initiated (config.txt and LOGxxxx.txt can be found in sd). However, everything written in the sd card is garbage. I have tried to open the txt with different encoding format but none of them provide sensible information. Beside, I am unsure how to input ctrl+z to get into command mode. I have tried to type in serial monitor of arduino sketch, but no character appears at the input line, and no response from openlog either. Could anyone help me to find out what is wrong with my connection/format selection?Since I am just a beginner in arduino, any useful information is welcomed. Thanks!
