WebUse the I2C peripheral in your Tiva-C or Stellaris Launchpad board to drive an input output expander to control the state of 8 LEDs connected to its GPIO port. Use the I2C … WebThe project consists of 2 Tiva-Cs (TM4c123x series) connected by a CAN bus; the first is connected with: PC by ESP32 WIFI module through UART and an external EEPROM (to store the passwords) through I2C bus, the second is connected with: MCP (SPI to GPIO expander) that illuminates a series of leds (like a robbery alarm), TFT LCD, touch sensor …

Web6 mag 2024 · The Arduino has internal pull-up resistors that are activated in the Wire library but they are weak and in most cases it's wise to add external pull-ups. Take care to add the resistors just once per bus (not for every device connected to it). Eternyt April 5, 2024, 4:52pm #11 I use the Respeaker. WebUsed for initializing the desired I2C peripheral. When you want to use I2C3 with 400kHz you need to call it like: I2CSetup (I2C3_MASTER_BASE, true); unsigned long I2CRegRead (unsigned long ulI2CBase, unsigned char ucSlaveAdress, unsigned char ucReg); sage middle school parker co

Web13 mar 2009 · My problem is the I2C read/write is getting in a twist. It appears the IRQ line is asserted but never de-asserted when there is data to read. The read fails as the third-party device NACKs the address packet. So any subsequent write fails. I am wondering if my interrupt handling in ok. Web5 gen 2024 · First the SDA line wasn't low but high. Second, I was using 1k pull-up resistors. So the actually issue was that the resistors prevented the slave or master to drive the line low. I changed them for 2k resistors and it stopped hanging. As an additional safety I added a watchdog to reset the Arduino if the program is hanging.
