Part Number: BQ79600EVM
Other Parts Discussed in Thread: USB2ANY
Tool/software:
Good morning.
I would like to communicate between my TMS320F28P65x via SPI with the BQ79600EVM-030, which is in turn connected to the BQ79718EVM.
To first test the setup (BQ79600EVM and BQ79718EVM), I connected USB2any to the BQ79600EVM to try it out using PC software (https://dev.ti.com/gallery/info/6994673/).
It works perfectly (USB2any uses SPI to communicate with the BQ79600EVM).
Because I want to understand what the signal for a wakeup signal should look like, I measured it in the meantime:
When I send the same signal with my controller, unfortunately nothing happens (the DVDD LED does not light up).
CS_PIN_CLEAR;
DEVICE_DELAY_US(3600);
CS_PIN_SET;
DEVICE_DELAY_US(99000);
CS_PIN_CLEAR;
DEVICE_DELAY_US(48);
CS_PIN_SET;
DEVICE_DELAY_US(50000);
CS_PIN_CLEAR;
DEVICE_DELAY_US(40);
CS_PIN_SET;
DEVICE_DELAY_US(39050);
CS_PIN_CLEAR;
DEVICE_DELAY_US(40);
CS_PIN_SET;
Does anyone here know exactly how this should be done (including how the other SPI ports should be configured during the wakeup signal)?
I would be very grateful for any help
