TimePlot cannot keep-up with received Data

Post by culdaraul » Mon Mar 26, 2018 8:28 am

Hello,

I'm trying to plot Accelerometer Data (both x and y accel on Y axis) using a third-party custom board (not arduino, program running at 32mhz and 3M baud with modified FT232 driver).

Problem is that the displayed plot in TimePlot tab is not accurate (I get more values on the same timestamp). Can you tell me if there's a configuration error in the program or a bug?

Hi, MegunoLink is not capable of timestamping data at that frequency. We typically recommend a maximum of 10 samples per second. If you send messages with your own timestamp (milliseconds using XYPlot) or using a Time Plot but with the time being supplied from your microcontroller then it should do better.

See this example for time sync
