Per the datasheet for tmp126, the maximum supported SPI bus speed is 10 MHz. We have our HW configured as the figure below per the data sheet, where our VDD is 3.3V.
After doing some tests, we are able to receive data on the PICO(SPI MISO) when we try to use low speed of SPI (e.g. 0.5 Mhz, we tried 1Mhz and not always working). In our application, we try to improve the performance as much as possible, could you tell me the valid operational range of the SPI speed for our setup?
Thank you,
