I2C_FLAG_TXIS is always in RESET state!!
Hi,I would like to use the I2C2 (from I2C3) in "STM32G474_MB1303_DRP_ONLY"besides, modify I2C3_SDA to I2C2_SDA (pc9 to pa8), I2C3_SCL to I2C2_SCL(pc8 to pa9), the AF to GPIO_AF4_I2C2, ...

Ping/ICMP checksum bug in Nucleo-F767ZI ? Firmware? Hardware?
I assume a bug in the Nucleo firmware (MAC driver? PHY driver?) or even the hardware.I have implemented ping.c (from Lwip) on top of the board's Webserver example (from the recent Firmware package), so that it can ping a computer.When the board issue...
I have Question about SPI protocol IP's of STM32L475VG DISCOVRY KIT. In polling mode master receive first 2 byte blank. like slave transmit multiple time = "helloworld" master receive like 1st " hellowor" 2nd "ldhellowor" 3nd "ldhellowor"
Mantion some details->in this STM32L475VG DISCOVRY KIT Rxfifo and Txfifo of spi is 32-bit data register is 16-bit ->data register is send on Txfifo and receive from Rxfifo

Trying to read VREFINT using STM32F103C8t6 (Blue pill) and getting wrong value.
Hey, I'm trying to read VREFINT value using internal ADC channel for vrefint, I'm converting data from ADC to voltage and getting 1.34-1.38 V. Datasheet says it should be 1.2-1.24 V. Why my reading has such error ? I'm using 238.5 sampling time for 8...
Resolved! Am I getting accurate results from the IBIS models? Is a rise time of 160 ps realistic for a GPIO at 1.8 V?
I'm doing some signal integrity verifications using the STM32H7 IBIS models to determine if I need terminations for connecting my STM32H7 to a HyperRAM memory.I was a bit surprised with the poor signal integrity I was getting, which I assumed was due...
How can the NVM content be changed from STPMIC1E to STPMIC1A?
Is it possible to reprogram the STPMIC1E to behave like STPMIC1A?
Resolved! reading the NOR flash ID and NOR SDFP of the stm32l562e_dk
I took the stm32Cube example : Projects\STM32L562E-DK\Examples\OCTOSPI\OSPI_NOR_ReadWrite_DMA and modified it to send a RDID (9Fh) instruction to the NOR. I get a "0xAC 0x28 0x53" but I ignore which codes that NOR flash is supposed to answer. It coul...
How to move interrupt vector from FLASH to SRAM when using stm32L476?
I want my interrupt handler to run in SRAM since some people seem to claim it is a more predictable solution then flash.I copied my interrupt handler to SRAM using __attribute__ ((long_call, section (".RamFunc"))) I tested the interrupt by toggling ...
How to start scanning available BLE beacons around me using B-L475E-IOT01A
I am using the B-L475E-IOT01A kit, but I am not able to find any BLE scanning example. I want to detect beacons around me and their details as well i.e RSSI, etc.Can anyone help me regarding this?
