STM32F401VC board demo

[ssena.1514]

Hi,

Can someone has STM32F401 discovery board to verify the Accelerometer functionality please?

​

Actually I want to extend the accelerometer functionality for another application.But sadly the accelerometer LSM303DLHC is not working in new application.

​

So to confirm that we have to deploy my demo.hex file to another STM32 board to check the accelerometer functionality.

​

So kindly reply if you have this particular board.

You could try the BSP drivers.

I still have an STM32F401C-DISCO on my table, so I can to test your HEX if you like. Just drop me a PM and add it there.

However, it will be difficult to replace the LSM303DLHC as it has been obsolete for years.

Hi Peter/Sir ,

Please take this attached demo.hex file .And we will be able to confirm whether the LSM303dlhc chip is ok or not.

So that I will proceed to buy a new external accelerometer chip module for this board if possible.

Please confirm after checking the demo.hex.

Example Description 

- Connect the STM32F401C-DISCO board to a PC with a 'USB type A to Mini-B' cable

through USB connector CN1 to power the board. Then red led LD1 (COM) and

LD2 (PWR) light up.

- All 4 leds between B1 and B2 are blinking as chenillard.

- Press User Button B1 (User) then MEMS sensor (LSM303DLHC) is enabled, move the

board and observe the four Leds blinking according to the motion direction.

- Connect the board to a PC with a second USB'type A to micro-B cable through USB 

connector CN5, this convert it to a standard mouse. Move the STM32F401C-DISCO 

board and see the mouse moves according to the motion direction.

- Press B1 or B2 to restart demonstration.

Thanks & Regards

This hex file, which is almost identical to the one that was already on the board and does the same, is fully functional: the movement is indicated by the LEDs, as does the mouse pointer.
