Hi,I have an STM32L552 MCU (the 1st) that has only two interfaces to the user, one through the USB-C and the other through Bluetooth. I have another STM32L031 MCU (the 2nd) inside the design that communicates with this L552 MCU through UART/I2C. Here...
Posted on March 07, 2018 at 13:01 EDIT: 14/03/2018 https://community.st.com/people/Schwaninger.Hannes found that we need to use RAM_D1 and not DTCMRAM of the memory area. This is not made by default when we use STM32CubeMx to set SPI ...
I am attempting to activate the bootloader mode on the STM32G050J6 (SO8N package). It is unclear to me from the documentation which pins are to be used. Currently, I am using pins 1 and 8 (USART1_RX and USART1_TX in the documentation respectively) as...
The board is STM32H747I-DISCO.I have configured I2C chip (PCA9555) properly, it works in interrupt mode.I configured BDMA for TX and RX, default options.I also have DCache disabled because I know it causes problems on H7.First, there are bugs in HAL ...
Hi. I am currently trying to implement USB headset on my old STM32F407 Discovery board.In USB descriptor I have simple topology with two input terminals, 2 out terminals and feature unit. Also I describe two streaming interfaces (IN and OUT) and one ...
