Hello,
I'm attempting to set the F28377S Launchpad up as an I2C Master to be used for testing purposes with a F28377D as a slave. The example code (Example_2837xSI2C_eeprom.c) compiles but produces nothing on pins 32&33. I changed the GPIO mux functions from pins 32&33 to 73&74 as the datasheet seems to indicate is necessary:
// For this example, only init the pins for the SCI-A port. // These functions are found in the F2837xS_Gpio.c file. GPIO_SetupPinMux(73, GPIO_MUX_CPU1, 1); GPIO_SetupPinMux(74, GPIO_MUX_CPU1, 1);
but I still see nothing on my O-scope on these pins. Just to be sure, I've also tried 42&43(the numbers indicated by the I2CA SCL/SDA lines on the "quick start guide") and 9&10 (the actual physical pin numbers on the board). Nothing seems to produce any output.
Am I missing something or is there an issue with the example code?
