LP5860EVM: LP5860 EVM

Part Number: LP5860EVM
Other Parts Discussed in Thread: LP5860,

Hello,

I am actually using the LP5860 EVM and I try to configure it with a Nucleo L412-RB-P card from ST Microelectronics wich integrate the STM32 chip. I did the register configuration on STM cube IDE using the register map on the LP586x GUI tool. Do you have any code wich runs with the STM32 and a schematic wich shows us how can we connect the different pins from the LP5860 EVM board to the Nucleo 412-RB-P.

Best regards.

Hi Abu,

We don't have any code or schematic compatible with STM32 chip.

If you use MSP432 microcontroller, the sample code is available from this LINK

Can the STM32 chip drive the LP5860 or I have to use another MCU chip?

Hi Abu,

Technically Yes, but I recommend TI MCU to avoid any potential compatibility problems.

Hi Aaron,

The problem is that I use exclusively STM32 chip and I can't change the MCU. Can you please send me a schematic which shows us the connexion between the MSP and the LP5860 EVM board? I think I didn't do a correct connexion between my MCU dev board and the LP5860 EVM board, I tried to do the power and the I2C connexion between the two cards but I didn't see any signal on SDA and CLK pins from the LP5860 EVM board.

Hi Abu,

Please refer to the schematic below and do the connection per your STM32 chip.

Hi Aaron,

I don't understand well the VSYNC and the VIO_EN pin, in the datasheet the schematic shows us that we have to connect them to an MCU if we want to drive the LP5860 driver with an external MCU. I don't know with what kind of pin I have to connect them with my external MCU.

Hi Abu,

For VIO_EN pin, it is a 1.65V~5.5V power supply which connects to VIO or GPIO

For VSYNC pin, it is connected to a PWM GPIO (if left NC, LP5860EVM can still work under Mode #1)
