Using the HAL I2C library, is there any way to generate a continuous stream of scl and sda without a stop bit after the chip address acknowledge and data acknowledge. Otherwise I am planning to use a i2C bitbang library any recommendations? The targe...
Have twin STM32H7B3I Eval systems.Had I2C between the two working perfectly, using HAL_I2C_***_IT functions, callback on transmit or receive complete calling osEventFlagsSet to notify waiting thread that transmit or receive is complete, no problem.Al...
I'm using the STM32 Io T discovery board (B-L475E-IOT01A1) to learn micro-ROS since this is a supported board with a demo use case.To flash the firmware on the board, the JP4 connector was set to 5V_ST_LINK pin and flashing was successful.The board a...
Hi!I wrote a program to write a .bmp file to SD card using FATFS. I am using STM32CubeIDE and its generated code. I converted my .bmp file to a byte array online and then copied the array to my program.If i write the whole data at once, everything i...
I am porting X-CUBE-CELLULAR to a new modem and host MCU. I am stuck at the initial modem initialization of the AT command channel when sending the cmd "AT" to the modem. The modem is Nimbelink TC4NAG and host MCU is Nucleo 144 F429. Flow control is...
All 'G0 except 'G06x/07x - i.e. including 'G0x0 - are in AN2606 described as Pattern 11; and Pattern 11 combinations involve BOOT_LOCK(bit).However, I see no BOOT_LOCK in the option bits in RM0454 rev.6.ST, please clarify.JW
Hi!I'm using STM32H747 MCU on STM32H747I-DISCO board and CubeIDE with a project template for 2-core parts. M7 core processing TouchGFX and all UI-related stuff. I'm trying to run a USB HS peripheral on a M4 core.Selected context for USB_OTG_HS is M4 ...
Have twin STM32H7B3I EVAL systems, connected to each other both by I2C and SPI2.For test purposes, implemented code in one system to act as SPI2 master for bootloader operation, and implemented code in the other system to act as SPI2 slave for bootlo...
Hello,I am using a Nucleo-L552ZE-Q board and I want to flash a hex file using another microcontroller such as Arduino Mega or Uno or Any. I Found AN3155 but not able to figure out so can I find an example or source code for STM32 bootloader IAP AN31...
