Resolved! TFT 16bit connections
Hello Everyone I want connect stm32F LCd controller to TFT lcd but 16 bit because I have lack of pins . how should I connect the RGB pins of STM32 to RGB pins of the LCD ? In case I use the LTDC contrller in 16bits , Can I use the unused pins RGB...
Resolved! STM32 Debugging not available
I am using STM32G031J6M6 and using NRST pin as GPIO.I have been unable to connect to STM32CubeIDE, CubeProgrammer and ST-Link Utility since then, probably because I executed __WFI() in the program.CubeProgrammer error codeSTM32 target not found! If y...
Resolved! Difficulty controlling character case on LCD display of STM32U083C
Forgive this short , pedestrian inquiry. I am using the STM32U083C-DK and the ST Micro provided BSP code and examples to write to the LCD display that is meant to be used with the DK. All works well, except the case of string buffer I give to the LC...
Display output does not appear when the start address is in SDRAM
I conducted an experiment with the following settings and results: LTDC - 0x20020000 (Internal RAM), Display - 0x20020000 (SDRAM): Display output is visible.LTDC - 0xC0000000 (SDRAM), Display - 0xC0000000 (SDRAM): No display output.LTDC - 0xC0000000 ...
Connecting a debugger probe to a chip in standby mode: L0 vs F103
Hello, I was testing f103 in a standby mode and wiring a nRESET line was enough to connect to the chip with a Segger debug probe in a connect under reset mode. But apparently L0 chips also require pulling BOOT0 pin high. I am guessing that is beca...
STM32G491 FDCAN: Issue with error counters
I have been simulating errors on the bus by removing the other node (a motor controller). As expected I see a number of failed transmissions. I can see that the FDCAN peripheral signals an Active Error on the bus (presumably as a result of not gettin...

Hello -Board - STM32 NUCLEO-L476GPeripheral board ADXL313 (16 byte data registers)Interface - SPII can perform single byte read, combine the 2, 8 bit values and the data is correct. Yet, when I try to perform a 2 byte SPI read, it's garbage. This wo...
Resolved! Debug Blue Pill with Stlink-V3minie
HI!I recently purchased some ST products, attempting to program and debug.I initially purchased a STM32 Blue Pill (STM32f103) along with a Mini St-Link V2 (Clone). Then I purchased an STM32F3VE board.I was able to program both boards using ST-LINKV2 ...
Resolved! STM32F401CCU6 takes 5 seconds longer to restart without backup battery
Hi everyone,I started a project a few weeks ago, which for reasons of urgency I had to use a black pill board as an initial prototype, using STM32F401CCU6 (of uncertain origin). The project continued to develop almost completely until we assembled th...
