diode
HelIo,I connected the anode from a diode to the operating voltage and the cathode to a pinx. I need ground to make the diode glow. How can this be implemented?

Resolved! Synchronous mode for DMAMUX - Trigger via EXTI
Hello community!I set up a dmamux channel, which is working perfectly in unconditional mode(direct mux). Now I want to use synchronous mode, where the EXTI0 line Interrupt is the trigger(or latch), so it initiates the DMA request transactions. I get ...
GRBL firmware for STM32 nucleo-F401RE
I want to install and run GRBL firmware in STM32 nucleo-F401RE board to make CNC machine where stepper motors would be driven by CNC shield.
Resolved! Stm32f042f6 - 'funny' problem with programming
Hi! Just as a comment, did anyone had that kind of problem?uC is not found or easily losing connection while erase/program.Everything is properly designed and soldered (even programmer pins are temp. soldered to board).Every connection was checked an...
Resolved! STM32H747 fails to generate PWM using some timers
I have an Arduino Giga (STM32H7), and I'm trying to generate PWM's. I succeeded using alternate function AF9 of PA7 (digital pin 5), which uses TIM14_CH1. Now, using the exact same code (as far as I can see) but using PA2/PA3 (digital pins 3 and 2) a...
Resolved! SB16 and SB17 solder bridge on a nucleo-f207zg within ethernet circuit stage
When you look at your Nucleo-f207zg board, ethernet stage, you can see: 1. (CN14) RJ45 connector.2. (U11) magnetic-transformer.3. (U10) TVS diodes for diff pair signals.4. (U9) LAN-PHY device. First appreciation:Then you can see that not connected RJ...
Resolved! Can we use NUCLEO-G070RB board for the development purpose of STM32G0B1 controller
We are currently using STM32G0B1VE. But we are having NUCLEO-G070RB evaluation board. Can we use the NUCLEO-G070RB board for developing the code before the actual board arrives?
NUCLEO H743, troubles with ADC and LWIP
Hello,I am currently working on a project involving transferring data acquired with an ADC through ethernet.Im am using the STM32H743 MCU.I have been building small projects using LWIP, and was able to connect to the board, ping and transmit some arr...
Resolved! Custom STM32 Nucleo 64 PCB without CN2
I am in the process of designing a custom PCB board that uses the CN4 ST-link pins to flash to the processor (rather than the standard USB Micro-B connector). Through testing with a multimeter, I have confirmed that the CN4 line is connected to the ...
Synchron driving with 2 STM Boards using external trigger signal
Hello guys. I got two STMF411RE Nucleo Boards and i want to start 10KHz pwm signals on each one of them with 25 microseconds delay between them and i MUST use an external trigger signal (Main synchronization computer) to trigger those STM's to create...
