Hi all, I am using a Digital Thermometer (https://datasheets.maximintegrated.com/en/ds/MAX31723PMB1.pdf ), which works by SPI in PMOD in the PYNQ-Z2.
I have written a code that is a kind of translation from a C code, but it always returns -1. It is as if it does not connect to the PMOD or something else is missing to make it work well. I have not found any example of SPI by PMOD to guide me.
Has anyone worked with any PMOD over SPI module on the PYNQ-Z2?, could you tell me what might be wrong or what I am missing?.
The code is as follows:
Connector Sup. Pmod B
lib_spi = MicroblazeLibrary(base.PMODB, [‘spi’])
length = 3
#spi .transfer(“NULL”, [0x01, 0x00], length)
print(read_data)
spi.close()
Thanks a lot!!!

Hi,
PMOD OLED uses SPI protocol. You can take a look at it:
