Hi all, I have some issues getting my DMA to interrupt correctly on my STM32F411RE. I recall that I previously had this working correctly, but even with my old code and solutions offered on this forum I cannot figure out what I am doing wrong at the ...
Hi everyone I am trying to implement I2C Write and Read with DS3231. I am using stm32f051r8t6. I do not want to implement this using CUBE. Kindly help me in identifying the mistakes I have done. I am able to write and read but what I write does not a...
Dear Members,I want to count pulse from EXTI4, and I tried to set 30 seconds for how many pulse ?Please correct my setting :void MX_TIM4_Init(void) { TIM_ClockConfigTypeDef sClockSourceConfig = {0}; TIM_MasterConfigTypeDef sMasterConfig = {0}; ...
I have a weird problem with one of the boards that I am trying to flash with a custom boot loader.Consider the following snippet:Reset_Handler LDR R0, =SystemInit BLX R0Most people will recognises it as being the first two ins...
I’m doing some frequency analysis - as usual I trying to minimise the processing cycles to minimise current consumption. I’ve only just discovered the Fast Hartley Transform (FHT). It seems pretty good ( and simple) - I wonder why it is not more wide...
Hi Im using a STM32L433 processor and want to incorporate a SD card . I saw in youTube a demo of using CubeMX and seemed to work fine. But after looking through this forum I saw there wasnt many people who thought the CubeMX version was good . Any ...
I'd LIKE to use SSCG to reduce the EMI of my product, but I found no effect by comparing the result before and after SSCG setting. And I can see there is no difference of the signal strength on the spectrum analyzer.What I have done is to follow the...
On the STM32L073 Nucleo board, I configured pin A5 as follows:GPIO mode (MODER): A5 configured as alternate function (0x02)GPIO alternate function mux setting for A5 is 0 (SPI SCK)Pull-up enabled on A5 (PUPD5 = 0x01)SPI1 peripheral is clocked but SPI...
I need to make a device that communicates (modbus) with a product that uses the rs232 protocol, with 7 bits and 2 stop bits. I use CubeMx and HAL libs. There is some process to do this. As is known in STM32, only have 8 and 9 bits in length.
