I have no issues talking to a MAX31855 with my Tiva LP fwiw. The resolution of the PIC16F877A ADC is 10-bit, which means the analog value after conversion is stored as a 10-bit number that varies from 0 to 1023 (0x3FF). Watch Video. I have modified the SPI Loopback example provided for the Tiva C TM4C123G, but am having issues when I try and send more than 200 bytes. In the waveform below it is 2 us between the x and y cursors. The exam-ples contain two functions for each of the SPI clock phase and polarity options: an example written in 'C', and for increased speed, an assembly routine that can be called from 'C'. beginTransaction(SPISettings(8000000, MSBFIRST, SPI_MODE0)) all wire. 4348A–8051–06/04 8051 Microcontrollers Application Note.
