STM32U5 – DMA for UART TX and RX

STMicroelectronics last STM32 release was with STM32U5 series, in Q4 2021. Product focus are extreme ultra-low-power features, enhanced security, integration, size and performance. Its advanced integration and performance options are key driver for new innovative silicon IPs. Product integrates new and most advanced DMA block ever seen in any of STM32 lines. Online training is available here. Key new DMA features Linked List : Define next configuration after first has been completed Option to work in low-power modes Selectable buses...

1-Wire over UART 0

1-Wire over UART

Today’s application mostly use somekind of operating system on microcontroller. Since these apps are not really real time anymore, keeping standard 1-Wire protocol developed with delays in software may make programmer’s life much harder and annoying. UART and 1-Wire protocols have 2 things in common: To reset 1-Wire network, we can use 9600 bauds on UART To read/write 1-Wire bit, we can use 115200 bauds on UART Detailed timings for the UART reset sequence, write/read bit can be found on...

HAL Library 07- USART for STM32Fxxx

Here it is. UART library for HAL based libraries. If you don’t know, how UART work on STM32Fxxx devices, then you might take a look at my first library, where I also explained how to used it. This library works successfully on F4 and F7 based devices for now. I will add support for F0 too as soon as possible. Library Read more about new HAL libraries Features Supports up to 8 UART peripherals at a time Interrupt driven RX...

Program STM32F4 with UART

STM32F4 devices have great feature. They can be programed with only USB to UART converter. Each device has bootloader inside, which supports UART programming. This is not very great method for Discovery boards, because they have better and faster solution on board, ST-link. But if you are working own board, then this solution can be quite nice. In this tutorial, I will go through step-by-step how to program device with USB->UART converter. I will use FTDI’s home made converter. This...
