Spoiler Hi, I have a question about the size of the flash of STM32G0J6. When i use STM32 cube programmer - CLI i saw that the size of the flash of the STM32G0J6 is 64Kb. I try to write everywhere in this memory it works. The datasheet say that the S...
Hi,I am trying to read Total 3 ADC Channel using DMA, Successfully completed and tested in Debug Mode. I had connected OLED to display the same in while loop. It works normally without DMA Enabled. But when DMA is enabled, Display is not working and ...
i was doing a project and while i trying interrupt in a normal program its working fine , but when inothe rprogram while im running some transmit function in while loop , the interrupt is not recieving and if i commenting that transmit function the i...
I have implemented a hallinterface (tim 1), to update my pwm timer (tim 8). But the delay i set is rather fluctuating.Disabling interrupt inside of the tim 1 interrupt did not help. And i think, outside of the interrupt it should not matter, since th...
I'm working on a custom STM32U5 board and I'm trying to harden the system.I followed the AN5347 (https://www.st.com/resource/en/application_note/an5347-arm-trustzone-features-for-stm32l5-and-stm32u5-series-stmicroelectronics.pdf) in particular I foll...
I detected that transmitting 68 characters using RS232 at 460800hz takes 30-32000 tics to micro running at 480Mhz (HAL_UART_Transmit() takes 10 times more).Is there a method to disturb less to micro to make that transactions, perhaps using DMA?Is bet...
Hi,i am trying to figure out, why this interrupt is delayed that much.The com trigger comes from timer 1, which works as expected. Also the delay here is as expected too (apart from a 50ns deviation). There is a delay of 1.3us, from the time i can ob...
Hi All!I'm doing a project on the STM32F429 discovery board.In this project, I've used the TouchGFX.Also, I'm using the FreeRTOS. The idea is to read the Temperature sensors and read their values to the TextAreas in TouchGFX.TouchGFX was tested and w...
I am now designing a board for STM32F103VET6 and would like to use the FSMC to control the TFT LCD (320x480 resolution)May I ask if there are any notes or guides that mention the layout requirements? Such as what conductor impedance should the data l...
Hi,i know the gotcha about the late clearing. My interrupt (yes it currently useless) is so short, that clearing in the beginning would not work either, so i tried to implement a check for the interrupt flag. But with no success: It is fired twice.Is...
