Part Number: TMS320F28034 Hi, One doubt about I2C on F28034 GPIO32 and GPIO33. One some pcs F28034, the signal on CLK is not normal in the left pic. The right pic is good. We did some test as: 1) A test code to test if the GPIO32 and GPIO33, it can output the signals well, when the I2C chip is connected (5K resistor to pull up CLK and DAT) 2) Remove the I2C chip, the signal is the same as the left one (bad). 3) Low our demo code, GPIO32 and GPIO33 can output the normal wave. What could be the issue? Thanks a lot. Br, Jordan
