Tool/software:
Hi Team, seeking for some inputs.
Using your ADS8343 16-bit ADC for a BMS. We had a couple of questions regarding the SPI communication with the ADC. For context, we are communicating with an ARM STM32 Nucleo-144 dev board. Vcom and Vref are both connected to 2.3V. I have attached the PCB layout of the ADC and our photo of the SPI communication below.
In our photo:
CLK in yellow was 375kHz.
MOSI in Pink.
MISO in Green.
CS in Blue.
We observe our sent control byte of 10010111, followed by the rising busy signal between the control bit and right before the ADC's conversion.
We were curious why:
1) CS rose twice during the conversion.
2)MISO in Green goes low 1.5 periods after the initial S bit of the control byte.
