I have a working code for SPI with DMA support added. Now I want to improve the speed of operation.I am using an STM32F427 controller.#define SPIx_Mode SPI_MODE_MASTER #define SPIx_Direction SPI_DIRECTION_1LINE #define SPIx_Dat...
Posted on October 01, 2011 at 01:15I found AN3126, which refers to ''STM32100B-EVAL demonstration firmware'', saying I ''can download this firmware and the associated user manual (UM0891) from the STMicroelectronics website www.st.com.'' I found UM...
Hi,I am playing around with Timers on Nucleo-G031 at 64MHz clocked from HSI and PLL.I use TIM1 with AutoReload of 6 and Capture/Compare Value of 3 to create an 9.17MHz 50% duty-cycle signal.The signals turns out to have 46.4ns high-pulse and 62.8ns l...
Hi everyone,I am having a hard time trying to get the max clock frequency out of the STM32H753ZIT6U.This is the revision V model and is capable of hitting 480MHz unlike its Y revision. This is my code to get to 480MHz:LL_PWR_ConfigSupply(LL_PWR_LDO_S...
I'm using FDCAN and UART (9bits) on a custom board STM32G0B1RBT6. The longer messages from FDCAN are split up in 8 bytes max and combined on the board, which works. I can see the correct array of data until the transmit function, but on the bus not a...
I am trying to read an analog signal from a sensor with the ADC of my board. I set the pins correctly I think ( DMA_continuous_requests enable, circular mode, etc. ) and I started the DMA with HAL_ADC_Start_DMA outside the while(1) loop and I put a b...
I am working with a Nucleo-L476RG and I am using PuTTY as an interface using UART. I am trying to use PuTTY to read a numerical value from the user and then store that entered value in a variable. Below is how I am initializing UART to receive user ...
