Hello, everyone! Has anyone used the I2C display module with the TM4C123 Launchpad? I'm trying to use this code as a test, but I was not successful. The version of the library I am using is 1.2.1 I accept other suggestions for using the i2c display. Thanks in advance! The code: #include <Wire.h> #include <LiquidCrystal_I2C.h> // Start the I2C address at 0x27 position LiquidCrystal_I2C lcd(0x27,2,1,0,4,5,6,7,3, POSITIVE); void setup() { lcd.begin (16,2); } void loop() { lcd.setCursor(0,0); lcd.print("test line 1"); lcd.setCursor(1,1); lcd.print("te

Thank you, Fmilburn! I was wrong when I was trying to use the library SoftwareSerial.h. Now just using Serial3.begin and etc and looking the arm's pin map, the program is working. Thank you one more time!

Hello everyone! I am using the SIM800L module to send SMS through a TivaC TM4C123GXL board, but its clock is 80MHz, and the library only accepts 20, 16 or 8 MHz. In Arduino it worked perfectly, this code found on a website. How do I reduce the TM4C123 clock in Power software? Is there another solution? Thanks in advance! The code: #include <SoftwareSerial.h> SoftwareSerial sim(3, 4); int _timeout; String _buffer; String number = ""; //here I inserted my number phone void setup() { delay(4000); //delay for 7 seconds to make sure the modules get the signal Serial.begin(960
