Segger RTT - How to increase maximun line count?

[muhkuhns]

I want to use Seggers RTT for data logging.. but after 199lines the Viewer starts to overwrite the old lines.. so that only the most recent 199 lines are displayed..

Are there by the way any other tools I can use instead of the standard one?

Hi muhkuhns. I have the same problem that I want to use RTT for data logging as UART printf() is too slow. In addition I need to log data from three devices connected to the PC at the same time. Therefore I would be verry interessted in your solution for that issue. Did you find a solution so far? Or does someone else know how to log data with RTT?

@ muhkuhns: I cannot see any other answer or comment in this thread giving a solution. The solution I described works but the performance is even worse than with UART printf. I have up to four values to be logged every 1ms. With UART printf I miss approx. 55% and with RTT approx. 70%. Do you have experienced any performance issues like this?
