Trying read data drom ATT7053BU by standatd library. But have nothing.
From digital analizer i see that sck signal is interrupted, but need continuous according data sheet . Program is simple
SPI.setDataMode(SPI_MODE1); SPI.setBitOrder(MSBFIRST); SPI.setClockDivider(SPI_CLOCK_DIV16); digitalWrite(CS, LOW); SPI.transfer(0x1B); SPI.setDataMode(SPI_MODE0); val1 = SPI.transfer(0); val2 = SPI.transfer(0); val3 = SPI.transfer(0);
Question, how to solve that it was no interruption in the sck?
