I am trying to get the USART3 to work with DMA, and so far have been unable to. After the initial cubeIDE project setup, I verified that standard (non DMA) RX and TX were working fine.Moving to DMA, I was getting Direct Mode Error interrupts, and a l...

I got a STEVAL-MKI191V1 Eval, and I am trying to write a wake-up driver for the accelerometer, but I cannot seem to disable the DRDY interrupt on INT1. I am writing 0x20 to register 0x23 (CTRL4_INT1_PAD_CTRL), but when looking at the scope, I see the...

I have not, but I figured it out. CubeMX when generating code incorrectly generates the init for DMA after the serial init when you have more than 1 peripheral in the project.Changing the order of the code makes it work

Miroslav, thanks for the reply. It seems rebooting the part fixed the problem. Not sure why, but I'll keep an eye on it. Also, since you work for ST, there are several typos in the register description section of the IIS2DLPC datasheet (DocID031788 R...

SCS serves as a chip select for both Serial and SPI interfaces - When using serial, can you connect multiple STPM32s in parallel, and use SCS to select which device you want to talk to ? The datasheet reads that way, but I wanted to confirm. Thanks
