The clock has transitioned to a low state but the FTDI chip drives the data line high after this has happened (ie because the 3-phase clock has been enabled). Lastly, in MPSSE mode, AFAICT it is impossible to to support clock stretching - a required feature for an i2c master. They got on the website of FTDI some examples, but all of their examples don't work for me. The most common devices that use UART are GPS units, MIDI interfaces, fingerprint sensors, thermal printers, and a scattering of sensors. ... 2 bytes (joystick); and the rest was garbage. For Power, I'm using from PC's USB port (with Serial Upload) and from another USB port soldered to 5V pin on the WeMos D1 mini module. 3. ", neverless, it's working 50/50% on I2C (same case with elechouse library) 2. Some I2C slave devices require additional time to process the data. I catched a condition by turning frequency, when master sometimes receives valid data, and sometimes wrong. Start and stop are easy. One rather clumsy but easy to implement solution is to toggle the clock line multiple (16) times before doing any I2C operation after power-up of the micro controller i.e. SCL - the I2C clock signal is on D0. It is because of FTDI does not support clock stretching, and MSP tries to reduce the speed on the 9-th bit of clock . ...
