UART+DMA sends data disordered or resends it. Is it a variable type problem?
Hello!I'm working this UART+DMA with idle detection and ring buffer. My STM32F4707VET6 receives data from a sensor and then sends it by USB, the data received by USB should look like this:$1651500,-5,-228,-988,-3,-217,-976,-102$1651510,-4,-228,-987,-...
HAL I2C library returning HAL_ERROR even though communications are succesfull
I am using the STM32F746VET6 with a project generated using MX v6.5.0.I am using interfacing to several I2C chips in my project and they are operation correctly. When I started checking the return values from the HAL_I2C_Master_Receive() function, ho...
g051 serial problem
HiI have made a board using the g051k6 chip. I have not been able to receive data from another board sending data at 115200 bd. I connected another serial port to the input pin , and all data is received without errors. A uart problem is mentioned...
stm32f303rc: SRAM parity error bit NOT SET, but NMI is taken
SRAM parity check is enabled. In fact, breakpoint in NMI is reached.But SYSCFG_CFGR2.SRAM_PEF bit is NOT set. See .png.Disassembly (at bottom) shows, that address of CFGR2 is loaded at R0 ("Registers" to the right) and its contents is loaded to R1. T...

Resolved! Switch from OctoSPI1 to OctoSPI2
Hello,currently we are successfully using an external NOR flash connect via Hyperbus on OCTOSPI1, ClockPort 1 for some time (~1.5 year).We would like to switch to OCTOSPI2 because we want to use the other address area (0x70000000UL instead of 0x90000...
STM32L 32.7680Khz Clock Problem
Hello, after several Years of using the 32L475RET6 with a 12pF 32.7680KHz Crystal and 8.2pF Capacitors we need to change the PCB to a 32L486QG. As to read in the Datasheet both have 5pF Pin Input Capacity. But the new Design (Chrystal about 1.5mm awa...
