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,we're maintaining assembly projects to teach baremetal assembly programming on STM32H750 board.Project used to compile without and warnings, but lately we're getting new errors.Project is stripped down to bare assembly and probably something is...

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.

Hello, maybe I'm wrong, but it seems that we can get USART1 TX and RX instead of SPI2 interface.I'm attaching my sketches. Regards.

Hi, thanks for response... I see now, it's a pity, that UART is not present by default.That also means that ESP (CN4) and Groove-NFC interfaces are not functional,since they base on UART device. It would be more usable, at least for our students...W...
