I am asking two related questions here:
I can see a program uart_echo for stellaris lm4f232h5qd . What I want is that I need to access this data on teraterminal using PA1 and PA2 pins instead of OTG. I have a RS232 to USB converter that I connected to PA1 and PA0.
PA0 is connected to the Rx of the converter and PA1 is connected to the Tx of the converter. The Vcc of the converter I connected to 3.3V pin adjacent to PA7 (near temperature sensor). I connected the ground of the converter to the GND pin on the same row where PA7 is located
The board is powered by a 3.7V battery. The +VBUS is connected to + terminal of the battery and the negative connected to GND pin near the SD card.
Then I plugged the USB end of the converter to the laptop,, and the smoke started coming from the converter!
The converted is useless now but fortunately the board is not having any issues.
Where did I made mistake in the above connection?
What is the correct procedure to access PA0 and PA1 pins of the board?
I want to get the Accelerometer data on the teraterminal. There is a pin on the board Ax, Ay, Az. I checked using a multimeter that if I move the board the values changes.
How do I get this data on the teraterminal?
Kindly help me resolve this.
