Resolved! looking for STM32F437IIH6 , 500000pcs. where can i find?
Hi all, looking for new original STM32F437IIH6 TR , 500000pcs. how and where can i purchase them ?
Hi, We have implemented USB bootloader for our project(Using STM32F7). We are using ST HAL libraries for our bootloader implementation. It was working fine fine with V1.2.7 and we are facing issue after migrating to new HAL i.eV1.2.8.
After completion of below checks, control is expected to enter into usbAppcallback function with via HAL_HCD_IRQHandler(). Interrupt is occuring but it is failing to enter usbAPPcallback function which changes the device state.
Resolved! Usable ADC5 inputs on STM32G473: Alternative functions of PortD in datasheet incomplete?
We are trying to make our first large project with an STM32G473VE MCU in an LQFP-100 package, but there seems to be a discrepancy between the number of accessible ADC input pins for ADC5 between the datasheet (rev 3, last version) and what I can sele...
Resolved! Swappable Tx/Rx pin configuration ?
The STM32F777 has a bullet under Section 2.25 [U(S)ART] :Swappable Tx/Rx pin configurationWhere can I find more detailed information on Swapping the Tx/Rx pin configuration for a UART ?
How to relocate Interrupt vector table from Flash to the internal SRAM for STM32L071CZ
Hi,I'm facing a problem with remapping of the vector table to the internal SRAM from Flash. I am working with the STM32L071CZ (Cortex M0+)(using the IAR Workbench and CubeMX ) .My __vector_table is presently at internal Flash @0x08000000Presentl...
STM32F401 low temperature problem
Hi, I am using STM32F401CCU6 on my circuit and it working well at room temperature. When I was testing the circuit in low-temperature below -10 degrees the RX of UART1 lost messages, when I came back to 0 degrees the circuit is coming back to normal ...
Programming Erorr
Dears I'm using board "STEVAL SPIN3202" to drive a BLDC Motor. To program the microcontroller , I'm using STM32 Motor Control Workbench software. The mode of driving is sure FOC since I'm using this software. The problem, However, happens when I acti...
Resolved! gpio let down 5 V pull-up
I use stm32f401's PB4 (NJTRST) pin. I attached 5 V pull-up resistor (5.1k) to PB4. While MCU is in reset mode the voltage on PB4 is 4.26 V. Only after starting the system, the voltage increases to 5 V. In my program I configure PB4 as input without p...
How to make NUCLEO-H745ZI-Q do anything?
I've been trying to make LED blink. GPIO PE1. So i wrote this code:HAL_GPIO_TogglePin(GPIOE, GPIO_PIN_1);HAL_Delay(200);When i'm creating procject for this board it creates two procject for each core CM7 and CM4 each with it's main.c. I can debug eac...
