Hello,I have simple project in assembly and can't understand/explain why one time delay loop takes much longer than the other one (LEDs should be blinking one on, second off and vice versa). But one such state takes approx. 5 times more time than the...

Hello, I'd like to change speed (clock prescaler setting in CFG1) and then resume sending bytes on SPI.Right now, I do :retval = HAL_SPI_Abort(&hspi2); My_SPI2_Init(SPI_EyeGenPrescaler);where My_SPI2_Init is just slightly customized version of Mx_SP...

Hello,I'm trying to generate continous stream of random bits on SPI MOSI (for eye pattern analysis).I'm making tests with 2 byte sequences.I'm starting DMA transfer with : HAL_SPI_Transmit_DMA(&hspi2, &spi_outdata, 2); in the HAL_SPI_TxCpltCallback...

Hello,I'd kindly ask for some help on determining exactly which MCU pin is connected to STMod+ extension board.Which pins exactly are connected to STMod+ pins 2 and 3 ?It seems like two choices for both pins, but I'm not sure how to check/modify whic...

Hello,I'm trying AudioRecord_demo() on STM32H750B Discovery and nothing happens. Touchscreen demos are working, not sure where to start checking things out. It seems that everything is already properly set to Microphone input and HeadPhone output.Has...

Hello,thanks for tips.Can I ask for more info about "alignments of branch targets"? I've extended the code with CYCCNT measurements, but I guess I'm doing something wrong, because it measures only for the first time, then it seems to repeat same valu...

Hello, any update on this? We're also getting same distance, no matter what.ID registers are read correctly... Is there any working example/docs how to work with this sensor? Thanks,regards.

Hello, thanks for response... It seems that I've forgot to start new send after reinitialization. Now it works...Regards.

Agree, not usable for Clickboards, but usable for breadboard connections and prototyping. Regards.

Hello, I meant PB14...So if you don't need SPI2 MISO, then you get USART rx, tx interface... But I guess clickboards with UART will have uart pins on RX,TX... So partial solution, but it is... Regards.
