SDC2150 over TTL issue

7 years 5 months ago #29528115 by JasonT
I have an SDC2150 and I\'m attempting to command it over TTL though pins 6 and 7. I can read my transmitted signal properly using a serial capture program but my motor controller does not seem to be recognizing the commands.

To test I\'m spamming the TTL port with the command \"!M 500 0\" every 500ms with a baud rate of 115200. I\'ve tested the command over USB and it works but over TTL, no dice.

According to the Roborun software, serial is given the highest priority and the watchdog timer is set to 1000ms.

Any thoughts or ideas?

I figured it out, I had to write a carriage return to the UART to confirm the command. It\'s a decimal 13 / Hex 0x0D.
