Tool/software:
Dear Engineer,
I am using the ADS1299FE-PDK connected via SPI to the STM32F4052 development board. The MCU SPI settings are CPOL = LOW and CPHA = 2nd Edge.
However, the data I read from the logic analyzer is as follows. According to the documentation I referred to, the result should display a square wave value, but the output does not meet my expectations. Could you please advise on which settings might be incorrect?
Below are the detailed test data.
Additionally, I noticed that in the printed data, the start values for channels CH1 to CH4 are consistently 05, 15, 27, and 23, respectively. This is quite interesting, but I am not sure why this pattern occurs.
output data:
