Other Parts Discussed in Thread: DRV8316
I am implementing C driver for the DRV8316C but I am facing issue with the SPI write.
By performing a read of all the registers, I get the following values :
IC Status : 0x00
Status register 1 : 0x00
Status register 2 : 0x80 --> weird thing here is that the reserved bit7 is at 1 but should be 0 (reserved read only)
Control register 1 : 0x00
Control register 2 : 0x60
Control register 3 : 0x46
Control register 4 : 0x10
Control register 5 : 0x00
Control register 6 : 0x00
Control register 10 : 0x00
Now if I want to do a write into the Control Register 2 to set the mode to 3xPWM :
[READ CTRL REG2]
[WRITE CTRL REG2]
[READ AFTER WRITE]
After this sequence of READ, WRITE, READ, the register remains unchanged.
Do you see any problem in this SPI communication ? Any clue ?
Thanks a lot for your help !!
