i use nrf52 DK as master and configure ads1292 breakout as slave. I have try the loopback example which works properly. I write the sample spi code based on spi_master_with_slave example to read the value of the specific register in the ads1292. what happen is that the CS ,SCL,MOSI signal are all correct, but the MiSO signal is always wrong.
yellow color is sclk,green color is miso, blue one is mosi,pink one is cs.
no matter what register i read, the green signal (miso)is always like that.
I attached my code as follow。
main.txt
the pin setting is changed like following:
#define SPIM0_SCK_PIN 25 // SPI clock GPIO pin number.
#define SPIM0_MOSI_PIN 23 // SPI Master Out Slave In GPIO pin number.
#define SPIM0_MISO_PIN 24 // SPI Master In Slave Out GPIO pin number.
#define SPIM0_SS_PIN 22 // SPI Slave Select GPIO pin number.'
please help me!
