Hi,I am developing an application with stm32g4 using the dual bank feature for firmware upgrades. To check if an upgrade was successful, I need to check the currently active bank.I can read the option bytes and get the BFB2 bit. But: if the firmware ...
Can we expect shortage issue to go away in the near future. Both JLCPCB and Digikey have been having stock issues for months. I'm unable to get the MCU I've designed my project around (F303C[B/C]Tx). Digikey only has the lower flash mem options avail...
I have an STM32H743 connected to a screen that uses ST7789 via FMC (i.e. parallel connection) using 8-bit bandwidth and A18 to select between command and data.The current code has an issue that the screen output is messed up (see pictures below) if I...
Hi ST member,I was shocked on how little information ST providing for GAP_OBSERVER_ROLE, Nordic supplier provide more information if compared to ST. So for I only found this info https://www.st.com/resource/en/user_manual/dm00162667-the-bluenrgms-blu...
I am working on STM32H753 microcontroller. I want to receive string using UART interrupt and send the same string back on UART. The IDE is keil uvision 5. The problem I am facing is that when I first program the MCU UART is working fine and I am rece...
When I increase the value of FOSR and IOSR,Iam not getting the proper values output from the dfsdm filter it keeps varying and is not also proper HAL_DFSDM_FILTERREGULARSTARTDMA(&hdfsdm1_filter0) How to keep the values of FOSR and IOSR?
Hi guys, I'm starting from a bare STM32G070KB, and cannot for the life of me get it to connect.I had this problem with an STM32G071CB but was able to solve it. The problem I was having was that I couldn't get an ST-Link to read the chip on a breadboa...
STM32F050C4T6A I want to use as a drop in replacement since I cannot find stock in the STM32F030C8T6 When I installed it in my board I use two I2C ports and they both work but the manual says there is only 1 I2C port. Am I ok to use this chip going f...
Hi,I am trying to perform continuous ADC conversions from a microphone using DMA, save that data to a large buffer, and then transmit that data using Uart (DMA). I have successfully setup the ADC to perform the DMA conversions along with saving them...
Hi, I have the problem that I get an endless slave Clockstretching.STM32F072 I2C configured with CubeMX, Primary slave adress $32If I fire a Tx frame from a master with for example:HAL_I2C_Master_Transmit(&hi2c1, 0x64, buf, 1, HAL_MAX_DELAY);The cloc...
