I've got a function that's literally only a switch statement, which is compiling to a compare, a branch, and a TBB instruction. Yet it's taking 48 cycles (as measured by TIM2->CNT before and after). How can this be? This is insanely slow. I've found ...
Hi everyone, I'm new to MCUs and programming in general and currently trying to calculate the average of the plateaus from 3 ADC input channels. I'm using Exponential Smoothing to reduce the noise and an algorithm to detect the plateau. Even tho my s...
Does anyone already have been generate three sine wave using stm32f4?
I am trying to use the OCTOSPI2 (connector MB1242) in dev kit STM32H7B3I-EVAL with the Hypebus PSRAM IS66WVH8M8ALL-100.I successfully configured the memory to write and read in memory map mode, however this can only be done if the write is immediatel...
Hello everyone!My setup uses a STM32407VG. I have been using for some time now and have gotten used to how to read the datasheet and use some of features. Today I am trying to get UART4 transmitting some data.Here is how I went about getting it all s...
Hi guysI have a real strange issuetrying to move two 8bits values in to one 16bit variable,can someone please tell me why this does not workIt should OR the lsb to the msb Sensor_Flow = I2C1_DATA[0] ; Sensor_Flow = Sensor_Flow << 8; Se...
i am using stm32f410RB Nucleo board i want to write and read some data in flash. In stm32f410RB 128 kbyte of flash and five sector, i want to write last sector this sector is 64k byte , but i want use only one page 2k byte, how can I erase one page...
My hardware design doesn't connect the BOOT0-Pin to a specific voltage level. That's why I need to write to the OPTR Register so that the BOOT0-Pin is not read at the boot sequence.I check the OPTR Register:FLASH->OPTR = ffeff8aa RDP = aa ...
Hello Comunity,I am trying to receive data with stm32h745 from stm32f407. In polling mode and IT mode no issue of getting multiple bytes of data. But with the DMA I can only receive and transmit one byte of data and nothing more. DMA is configured in...
I use STM32H747 eval board to try to develop my application.In the standard example the two MCU (m4 and m7) boot togethere and then M4 goes to STOP mode until M7 Release HSEM.I want to to the same thing but i need to M7 goes to STOP mode and M4 resta...
