how to get stm32-v3set with Stm32CubeProgrammer to program STM32L041?
PC connected to STM32-V3SET via USB. PC COM3 sees the STLINK.STLINK is using CN7 UART TX and Rx lines to L041 USART2 configured pins PA2 & PA3. GND too.L041 has BOOT0 pin on a wire, to allow high or low level at reset.L041 has SWD-loaded program i...
Resolved! I am designing a high-performance line-following robot, and I would like to know if my schematic is correct?
I am designing a line-following robot that also avoids various obstacles (two digital infrared (IR) sensors), but I am a bit confused with my schematic since I am a beginner in electronics, and that is why I would like to know if my schematic is corr...
Misprint in UM2407 (Rev 2). In table 20 (CN9 pinout) pin 15, the STM32H7 pin should be PE9 (it appers PE0).
I don't really know where to inform this.Thank.
Resolved! Conflict between SMPS and LDO regulator during startup on STM32H7 microcontrollers.
I am working on a PCB design with a STM32H735IG uC, and I would like to use the integrated SMPS to provide VCORE directly, without the LDO. This corresponds to figure 19.2 of RM0468 (the reference manual). In this configuration the VFBSMPS is connect...
What is the specific part number used as the pin headers for nucleo 144 boards?
I want to stuff the extra connectors so that I can plug the nucleo onto a backboard, but I want to make sure that they are the same length.. I have been unable to find what appear to be compatible connectors in stock anywhere?. This has to be a fre...
Resolved! [RESOLVED] Why IAR EWARM debugger resets STM32F7 in a weird way
Apologize for IAR specific question, hope someone here can shed some light on my problem. I've tried to ask IAR support, but looks like they have a long weekend or whatever.I have a bootloader at 0x08000000 and main app at 0x08008000.The bootloader ...
Good morning all, I have a board to test with n.4 L9026 in daisy chain, driven with a microcontroller STM32G0V1ET. Unfortunately there are no examples on ST website and I am not able to switch on outputs. Any idea?
// Init L9026 // 00 CHIP_ID, default // 01 CFG0, output high side // W=1,ADD=1,DATA=00111111,P=0,FR=0 HAL_Delay(2); // Set CS lo on L9026 GPIOD->ODR&=(~0x02); // PD1 = 0 data16=0b1000010011111100; SPI_Out_Buffer[0]=SPI_Out_Buffer[2]=SPI_Out_Buffer...
